afam4eva:Are you aware that your website is offline and that it is reported that your domain name has expired? |
baby4u2:You may send an email to afam@justwebservices.com and I will advice accordingly. Basically, there is not business process or idea that you want to turn into software or online application that I cannot do. All that is required is for you to be clear on the requirements, features and functionality. |
chidichris:Who indicted Bode George? EFCC under Ribadu or Farida? It seems you are not at home with facts anything you make crazy comments on this forum. |
Jakumo:No wahala. Enjoy! |
Jakumo:Hi Jakumo, Thanks for your post. 1. The inverter technology is pretty a mature technology with different topologies and implementations hence the variety you see out there. The main problem is with the battery chargers where the charging rates are usually either too high (kills the battery bank faster) or too low (cheaper to produce but still kills the battery bank at a slower rate). This means that the battery charging amps must be designed to charge a given battery voltage and amps properly. This would also mean that the manufacturer must have information about the typical battery Ah that will be used with any capacity inverter (with an integrated charger) instead of the one size fits all scenario we have today with mass produced inverters. 2. Another problem is that some design assumptions made by inverter manufacturers outside Nigeria work well in their countries while they don't here because they don't have the type of embarrassing power problem we have down here. That is where some inverters come with very small charging amps with the basic assumption that these inverters are used for say emergencies and should have more than enough time and power to recharge the battery bank when depleted. You know that in Nigeria here you can barely guarantee 8 hrs in a day. 3. Then the components matter. The same way the average Nigerian wire is termed the most reliable and expensive in the market is the same way the transformer coils that are assessed locally are more reliable than most imported transformers with aluminium rather than copper as the choice. The choice of transistors again has a huge impact as some transistors perform better in certain scenarios based on what features you prefer. Management of any heat generated is another issue that if not handled properly can damage the components. So, there are a lot of issues why you have a varying degree of reliability of inverters out there. We build modified sine wave inverters and you can't use these inverters for any sensitive medical equipment, laser copiers, laser printers but works ok with over 95% of electrical or electronic appliances out there. True or pure sine wave inverters are the best in terms of wave output but generally cost more. Now to the questions 1. It is difficult to state the best inverter because I have not tried many, in fact I have been able to install just one imported true sine wave inverter in about 6 years and after that experience I decided not to do so again because in the cause of diagnosing the problem that came up in the 11th month of usage I found out that the charger was just 6 amps for a 5KVA 180VDC inverter that provided more than 4 days backup until the problem came to the fore. Obviously, the battery bank had never seen full charge since installation date and was able to hold out for that long because the batteries used were the best I have seen and used myself. Power safe brand of Enersys batteries is the brand. But these batteries are really expensive. To give you an idea of how expensive it is, a typical good 12V 200Ah deep cycle battery hovers around N50,000.00 but the landing cost of the Power safe brand with the same 12V 200Ah comes to about N125,000.00. Batteries from USA or Europe generally are more reliable because they use virgin lead in the battery manufacturing process whereas in Asia the use of recycled lead is common and basically an acceptable standard. You still need to beware of American battery makers that have manufacturing plants in Asia because the plants in Asia may as well build these batteries with recycled lead and probably ship them to Africa or other countries that don't pay attention to standards or insist on certain standards. So, when it comes to installing inverters the only ones I can guarantee the workability and offer 1 year warranty where repairs or outright replacements are done at zero cost to the owner are the ones we build ourselves because we have 100% control in the building process from the components selection to the setup even though the building process is not automated so cannot produce them in large quantities and only do so based on orders. 2. Any generator system that runs during the day can support a reliable inverter backup system at night, in fact this hybrid system will be more reliable than a typical PHCN/Inverter system because PHCN does not provide power everyday. However, unless the items in questions are listed (with their power ratings) no one can give you any reasonable information as regards the inverter capacity, number of battery banks required and their associated costs. Doing so would amount to going into a war with a blindfold. Even at that an energy efficiency program may be implemented to crash the loads. It is always cheaper to replace some items and build a reliable inverter backup system than it is to build an inverter backup system to support any current load that are not energy efficient. For example, an inverter backup system that will provide 24 hrs backup for a desktop computer would provide between 72 hrs and 96 hrs for a laptop computer. Same with other loads with more energy efficient alternatives. Sorry for the long post but needed to clear up some issues that have been misleading or misunderstood in the power inverter area. You may read more articles @ justalternativepower.com/articles.php Please, address me as Afam, just Afam. Enjoy the rest of the weekend. |
AjanleKoko:Yes, I build web applications and develop custom software when I am not designing and installing reliable inverter backup systems and I am very proud of what I do. However, I served in the same Mobil Producing Nigeria 2 years before you attempted the interview as a youth corper and failed woefully. Just limiting this to one issue at a time. As you bring up more issues I will respond accordingly and trust me by the time you are done you would have realized that in terms of work experience and value of projects handled you may never be able to come close regardless of your many claims to work in a GSM company. |
Enjoy the rest of the day. |
Vavavoom:Thank God you have summoned the courage to ask the question. I have no business with your capability as regards being able to afford anything because as long as you cannot offer to pay hundreds of millions that I roundly rejected based on professional integrity what you think you have as regards money remains minute. However, I will not be providing you with the answer you desperately need until you learn to ask questions like a normal human being. |
Vavavoom:It seems you have what I call a comprehension limited problem? Who is suggesting a solution to you? Keep deluding yourself unless of course the total value of your items is N10.00 as used in the example. You should be capable of understanding basic issues instead of hiding under the banner of the example does not apply to you because I have made it clear that I am not interesting in providing the answers you are desperate to get. Thanks for raising other issues now that common sense has prevailed on issues you have been confusing yourself with. However, I won't be responding to them considering the fact that you don't deserve to know the answers. |
I made it clear then that the law makers handling the power probe were playing to the gallery as they did not understand what EPC contracts entails. Anyone that understands the nature of these contracts would know that it is possible to spend 70% of both time and money for the project without seeing anything on ground as they were screaming then. And these are the people responsible for making laws for us. |
Beaf:What I have come to realize is that the average Nigerian does not know his rights and majority of those that even know their rights are never ready to enforce those rights out of fear. Some engage in the same corruption they criticize without any shame. Working together would be great but as they say - would two people work together unless they agree? The rate at which people are ready to go to war instead of admitting mistakes worries me a great deal and this is even common with the educated ones that should know better. I try to sanitize my own space by insisting on what is right at all times, saying NO to corruption at all times and encouraging others to do same. You don't pray at night for God to protect you from armed robbers and then leave all the doors and windows open. So, we should not expect the government to change overnight as most powerful and rich people in Nigeria today can only thrive in the current corruption ridden system. That is why they are ready to do everything possible to get into power and once they get in they are ready to do anything to remain there. |
Vavavoom:Who is talking of ridding one's self from PHCN? Did I ever make a statement like that? It seems you have finally gone round the bend and you keep manufacturing one lie after another. The same way someone who buys a bag of pure water will spend less when compared to another that buys the same number of sachets that you have in a bag one at a time. Don't go far with your manufacturing of lies, stick to the facts stated. I develop software and bought the same small generator (I pass my neighbor) for N13,500.00 in 2003 and after one year I did an estimate of the cost of running that generator and it came to about N125,000.00 and this is even an office. In 5 years, I would have spent about N1M because the cost of fuel has changed from what it used to be in 2003 now. However, I chose to go the alternative energy route and even though I had to start with a regular trailer battery (because I didn't have enough information on the suitability or otherwise in backup systems) the total cost of the inverter and the new battery bank is still less than N200,000.00. This comes to about N40,000.00 per year and could go to about just N20,000.00 per year if the battery bank remains ok in the coming years. You cannot eat you cake and have it. Of course, buying a N13,500.00 generator seems cheaper to any inverter let alone the battery but I am a practical person. I am not interested in sentiments as I have respect for facts, hard facts. You may raise the issue of the banks financing anything with banks as I don't own nor run any. |
nex:In fact, na for internet I even see information about the man even though I don dey use Zain since I never get any information about the man from either Zain, Celtel, Econet etc. Let the law makers concentrate on making laws that will make Nigeria better as that is what they are supposed to be doing. |
Beaf:Maybe, for the wrong reasons sha. Maybe when they cannot cheat them at will without any consequences. One good thing that will come out of difficult times is innovation. When there is no free money to spend (from the government to the individual) then we begin to question our spending habits, the quality of products and services, projects that may not be viable etc. I can understand difficulty due to things outside our control but for corruption induced difficulties only execution would do to help in that regard. Development cannot be about personal wealth because a rich man in the midst of poor people is inherently poor because the problems of the poor by extension becomes your problems too when they have to come to you for help. Security nko? You get to build a house that looks like a prison yard, spend money installing security gadgets and hiring armed body guards and police men. So, in my opinion collective development is 100% better than personal wealth. |
Vavavoom:As predicted the guilty will always go down the same route - initiate insults and when responded to in kind begin to complain. This is one claim that no one can dispute about my comments and disagreements with people. Why would I turn to insults when I have things to say to back up my positions? Only those that run out of ideas resort to insults when losing out in any argument. However, the right to respond to any insult in kind is a fundamental right which I intend to exercise till tomorrow so that idiots like you who think you can insult people just to hide your ignorance would be put where they belong. |
Keep shifting the goal post. From no cost effective solution to solar panels and the inability of Nigerians to pay for the inverter system even though you agree it is cheaper than running generator. Learn to be consistent. I never talked about solar panel so it may be you that is not at home with reality. I have never used a generator in my office for over 5 years - this is practical, not buzzword or marketing gimmick or even false claims. I hardly use a generator at home - this is practical. I provide information to people and write articles to push the same information out anything I get too many questions on any issue concerning alternative energy. So, I don't have any problems providing answers at all but not to people who would label your comments as nonsense and yet expect you to help them provide answers they desperately need. It is rather disturbing that you fail to understand what cost effectiveness means, for the benefit of others I will delve into it so as to get you out of your ignorance. If you have N10.00 worth of items and need N90.00 to provide power using generator for say 5 years then your total cost will be put at N100.00. If you have to spend N20.00 to replace your items that would crash your energy need which in turn would require a must lower capacity generator or inverter backup for say N40.00 then in the same amount of time you would have spent N60.00 as against N100.00 and that represents at least 40% reduction in cost. I still maintain that the average educated Nigeria lacks what it takes to analyze issues without unnecessary sentiments. Add intellectual stubbornness to the equation and you get complete disaster. Handle your inconsistencies and leave the other guy alone because he has enough on his hands as his confusion is coming to the fore for all to see. Not that I expect you to understand anyway. |
AjanleKoko:1. The insider angle you are harping on remains one out of many reasons for the ATM card fraud so no need repeating the obvious. I stated that much in the article so don't make it sound like you are bringing up something new. 2. You are desperate to shift all the blame to the banks and none to the current technology and implementation of the technology. This is embarrassing for an engineer who should always challenge technology and make it better, safer and cost effective. It seems we are on 2 parallel lines here as it is obvious you don't understand my position due to your own mindset. 3. I am currently doing some email correspondences with a client and the bank handling the payment gateway implementation. Basic programming knowledge is lacking on the part of both the bank and the payment gateway provider and I have been able to demonstrate (with proof and evidence) where the problem is just because they are finding it difficult to change a return parameter to something the program wants instead of generating new transaction ids as regards the default implementation. So, don't even go there as I have my hands full on implementation of technologies from software programming to e-commerce solutions with 100% flexibility in the codes and features requested. I have had to discuss with and help develop security based software for people that were even FBI trained so while I don't intend to give you my CV I must tell you that I never dabble into what I don't have a good understanding about. |
MrCrackles:I am really sorry for this but one thing I will always do is respond to posts in kind. The idea of ignoring people who throw insults or try to question other peoples credibility don't seem the best to me as failure to address issues may lead to misunderstandings. I have never insulted anyone and will not do so but when and if insulted just because I hold a different view by anyone I will always respond in kind and on time too. |
Vavavoom:It seems I touched on something that hurt you real bad. You are confused - You agreed with my take on inverter backup (as being cheaper than running generator) but claimed the initial capital outlay is high and yet you want us to believe that there is no cost effective solution for your items. You are a hypocrite - You replaced your bulbs with energy saving bulbs (according to you) but claim that talk about energy efficiency program is nonsense. You have ego problem - You want me to help advice on energy efficient alternatives for your items and inverter backup but pride would not allow you ask as any reasonable person would. Conclusion - You are simply too daft for me to engage you in any issue based on technology. |
AjanleKoko:It is obvious you are definitely not understanding the issue. When in doubt ask questions. You believe the insiders in the banks are responsible for ATM card fraud and you believe phishing sites are the second problem. This may be convenient to you because you are interested in limiting what you know to what you were presented or asked to work on. I am talking about how to mitigate against the sharp practices. If you could pay attention to details then you would understand why address verification for online transactions will reduce the incidence of ATM card fraud. There are documented instances of web based withdrawals running into over N500,000.00. I know of one so this is not about may be. Would the person have been able to do this is all he had were card number, pin number and expiry date if the system required address verification? I am not surprised at your take because you come across as someone who is intellectually stubborn and believes he understands everything. Yes, I normally check comments of people I disagree with so as to understand the level of intelligence and comprehension. You don't expect me to argue issues with everyone that comes around as doing so may be a waste of time if the person cannot comprehend basic issues. The content below was from your posts and I am happy other intelligent people told you to your face what your problems were. 539 Forums / Career / Re: Engineering Vs Medicine "which Is More Challenging?" on: February 17, 2009, 10:44 PMAnd yet you claim to have 11 years experience even when you sat for a basic corpers interview in 1998 and claimed to have abandoned youth service to get a job somewhere? In an organised setting you won't even have to opportunity to wear any organisation's ID card. I don't have patience for people who do not know and would not be bold enough to accept such fact. |
The 2 problems you listed I believe were mentioned in the article and unless you are hell bent on twisting issues they are very clear. I don't need to work with the banks or the payment gateway providers to understand what it takes to build a secure transaction channel because I go beyond what is usually obvious as I am well aware of the guiding principles, standards and protocols guiding e-commerce including credit card payments. By the way being an "insider" (as claimed by you) should give you better understanding of the working of the ATM and allow you to accept criticisms that are logical which is supposed to enable you provide better services for the customers. I will ignore the part about listing the e-commerce websites I have setup as I am not allowed to do so based on non disclosure agreements so you won't be getting any names from me. This is the typical problem with Nigerians, you punch your keyboards without thinking through just because you are in a hurry to criticize. For all the noise and claims you made you ended up listing 2 out of the problems I listed and you insist that they are the only problems while leaving it the area you may have been involved in - typical Nigerian, blames every other person but himself/herself. The content below was written by you barely 3 months ago. Why would a well implemented card payment system be in place and even mastercards and visa cards domiciled in Nigeria can't be used outside? Nigeria is in a sorry state because people like you want to think for others instead of providing factual information and letting the reading public comprehend the facts provided. 119 Forums / Career / Re: Welcome To My Office on: August 10, 2009, 05:11 PMYou should be bold enough to accept responsibility of what you know and what you don't know. There is an on-going Class suit based on ATM card frauds. Nigerians are losing their money everyday without understanding why. Cards are being cloned and used to access accounts and you tell me there is nothing unsafe about that? I implore you to understand the technology and see how easy it is to mitigate against the current problems instead of trying to defend the indefensible. By the way I am not upset. I have come across people who brag like you even when they may never know as much as they claim to know in reality. |
MrCrackles:It seems you have forgotten that Nigerians prefer rumors, gossips and conspiracy theories to facts and truth. |
AjanleKoko:I believe card technology, ATMs and e-commerce are supposed to work together to make buying and selling easy regardless of any physical boundaries. Any combination of these that make the processes unsafe for even people who do not care about e-commerce but still have to see their funds withdrawn from their bank accounts without their consents does not make sense. Elementary knowledge of anything based on facts that cannot be disputed is 100% better than what you think you know that you may want to discuss with people you may want to rip off. In any case, I know a lot about card technology, how cards are programmed, how card readers work, how ATMs are just computers with note counters and printers and what e-commerce entails because I develop e-commerce websites from scratch and implement custom coupon based payment gateways that are not only safe but running flawlessly as I write this. Do not question my elementary knowledge, question the facts provided and counter them with logic, facts, relevant knowledge and common sense if any. I am sick and tired of people who do nothing but criticize others even when they will not state any reasonable thing on the issue at stake. People who have never used the internet to make payments with their ATM cards or given out their card details to anyone are losing their money without any end in sight and all you do is brag about filling different shipping addresses while card processors decline some of them and you still claim you were not doing anything illegal (read the post that was flagged off as spam). |
Vavavoom:I am not a sales man and I don't run after clients. I choose them and provide reliable backup solutions for those that are serious. I do not believe that the customer is always right and I have written an article on this. So, when you refer to comments as nonsense and in the same post ask for answers to questions you clearly do not have answers to I see it as a non starter and trust me I have rejected projects running into hundreds of millions by banks based on professional integrity. I have designed and implemented up to 1 week back up for people including 1HP A/C just as I have installed systems for ISPs that have minimum of 3 days backup for all essential components of their business. However, I will opt to allow you to continue wallowing in your ignorance not because I don't have the right answers to your questions but because you don't deserve the right to know based on your own attitude. I provide information freely to Nigerians that will benefit from them and I don't believe I know everything but for those things I know trust me I owe no one any apology for knowing them. Keep going round and round in cycles. Maybe, people around you tolerate your attitude but I am not under any obligation to do the same, sorry. |
Bishopking:This is the "Can do" spirit we need to imbibe. I don't believe in buying technology if you don't understand it. This is the very reason why a lot of Nigerians are losing their money in different banks due to poor implementation of ATMs by the banks and the payment gateway providers. Did a piece on this some days ago - http://www.technologytimesng.com/post/the-real-problems-with-atm-card-fraud-in-nigeria |
Vavavoom:Maybe you get information from people with your rhetorics but trust me I walk people like you out of my office because you find it difficult to even accept responsibility of what you don't know. Good enough you are using energy saving bulbs but do not know about energy saving alternatives for the items you listed and I believe you want someone to advice you accordingly yet you term energy efficiency "baldderdash" even when you implemented same based on your limited knowledge. Is this not unadulterated hypocrisy? You can be on this all day but I would rather you continued to wallow in clearly avoidable ignorance. |
Vavavoom:I would want to assume you are educated enough to learn more on issues you want to learn more about especially as regards the energy efficiency program which by the way is common sense and not buzz word considering the fact that 15 nos 60W incandescent bulbs would take about 900W every hour whereas 15 nos 5W energy saving bulbs would take just 75W every hour. This is a reduction in energy requirement of 12:1 which means you get to pay 12 times more to PHCN if you are using the old bulbs, spent a lot more to get a generator, burn more fuel to get the power out and if considering a backup system you will definitely spent a whole lot more. It is not my duty to point you to all the available alternatives in the market especially when you see the comments as "baldderdash". Why seek for information on something you consider "baldderdash"? |
Vavavoom:Consider an energy efficiency program first. You cannot be talking about an alternative energy system without reducing your load requirements. Sometimes, it is much cheaper to replace your energy hungry loads with energy efficient alternatives than to build a backup system that will support the energy hungry loads. You could achieve up to 50% reduction in your current load to begin with. |
Vavavoom:My emphasis is on facts. It is easy and looks cheaper to buy a generator for N13,500.00 and then spend about N150,000.00 every year to run it than to get an inverter backup for the same loads (with energy efficiency though) at say N200,000.00 or N300,000.00 that could last for at least 5 years. So, it is not about sentiments it is about facts. Facts that cannot change. Do the most conservative estimate of running generator in Nigeria year in year out and I will tell you why a well designed inverter backup system will always be cost effective. |
That is why I say that the average Nigerian finds it very difficult to analyze issues and seek ways to free himself/herself from the shackles of these corrupt Nigerians. After spending just N125,000.00 in a year to run a small generator I bought for only N13,500.00 I knew generator would certainly not be the way forward if I intend to run my business properly otherwise I will be working for the petrol station guys and their owners. This made me to look for alternatives and I ended up doing a lot of research on alternative energy, six months later I settled for a locally built inverter backup system and for over 5 years now I have not used a generator and the total amount spent on the backup including changing of the battery bank for these years is still about N200,000.00 which translates to about N40,000.00 per year and it seems I will still see another 3 or 4 years from my inverter backup system before the battery bank begins to get tired. And, I cannot work without electricity considering the fact that I am a software developer so this guarantees steady power supply even when I would have spent over N1M running generator in my office. If Nigerians seek for alternatives the cartel will not force anyone to buy generator, fuel or diesel. While I agree that the best way forward is for PHCN to generate power instead of turning typical Nigerians into alternative energy people the most cost effective solution for now remains a well designed inverter backup system. |
dababex:You can't offer unlimited bandwidth or unlimited email accounts on the cheap because bandwidth costs a lot of money. Now, as regards running a regular web hosting business in Nigeria I won't advice that since no single ISP is reliable regardless of their claims. By reliable I mean 99% not even 99.99% and the customer service support of even the most popular ISPs don't measure up. If I can get a reliable ISP I will run a successful web hosting business here in Nigeria and throw in a full 30 days inverter backup system to guarantee steady power supply. |
The level of power supply in Nigeria generally is enough to guarantee steady power supply for those who use well designed inverter backup systems. For over 5 years now I have never used a generator in my office and I can guarantee steady power for 3 1/2 days without power at all. My point is that though power supply is poor it is not a good reason to shut down businesses or refuse to make progress. The fact remains that Nigerians find it difficult to analyze issues based on facts and it is common to see people spend 20 times more on generator and diesel/fuel than they would spend on inverter backup systems for the same power provided. I call this madness. We should look at the distributed power generation and distribution model. Currently, we have a monster that is way too big to be efficient. |

Only generic theories, common sense knowledge and roadsideikoku solution. So you should know, materials on alternative energy and its applicability are prepondorant, all over the internet and at a snap. Currently have someone installing a safe-mode switch system that can shut out my ''power hungry loads''tanx for this term sha
when PHCN goes out while keeping the manageable loads afloat. My discussion with you was to see if you could profer a better option than am currently installingapparently not
. Oh by the way my batteries are German3, 180Amps. All this is possible because I can afford it, the many 75%chappies/folks below the $1 mark can't. That is the crux of the matter, the many who need it for their saloons, shops, and petty trading businesses! You can keep your N10.00 analogy now, mr facts.

an item that isn't on my list! I would accept if you need to research more instead of this energy bulb bravado you are trying to pass as on. Energy bulbs are easily replaceable and aren't capital intensive Mr. Facts man. It is not my worry as all of the bulbs in my house are energy bulbs. You will get me dancing on the floor if you can get beyond the small fries without my needing huge capital outlay.
