The low power suply in the nation are forcing many out of business today. many that their businesses need steady power suply are having rethink on whether to change business will be the best alternative. recently i was reading on paper were coolroom operators were crying for lost. one of the owner of this coolroom said he is spending more than five hendred thousand naira {#500,000} monthly on diesel and fuel to keepup with business. this amount is alarming.

you don't need to spend such amount on diesel or fuel. we have solution to you power problem.
it is unfortunite that quite a few number of people know about this modern technology in the market. {INVERTER and SOLAR PANEL}. Inverter is a power generator that uses battery instead of fuel or diesel. when acquired you don't need additional cost to run it.

we build, sale and install inverter. we also are cuurently running bonaza on youth empowerment pragrammne which is aiming to empower our youth on how to be independent.

we have the following range of inverter depending on what you want to use it for: 1000w{1KVA} for #25,000, 2000w{2KVA} for #35,000, 5000w{5KVA} #90,000. 10KVA for #200,000. etc.

we can as well get solar panel for you. we sale our product with one year gurrantee.

with solar panel empowered by inverter you can say bye bye to PHCH, as you are sure of 24hrs steady light.

call us for inquiring on our current promo on training or order for your inverter today.

contact us on: 08063396935, 08027298469

stop waisting money on ful and diesel.

bro can we know the servicing times and pertern before we are bamboos again

My inverter runs down quickly after charging (less than 2hr) even though its lights show its fully charged. Can you help? What could be wrong?

1000W is not the same thing as 1KVA
2000W is not the same thing as 2KVA
5000W is not the same thing as 5KVA

My inverter runs down quickly after charging (less than 2hr) even though its lights show its fully charged. Can you help? What could be wrong?

The battery charger (usually integrated in the inverter box) could be the problem.

The battery itself could be the problem.

Increased load could also be the problem.

Get in touch with the supplier or builder of your inverter.

The most difficult problem to sort out is the battery because if the battery has gone back or is dying you will have to buy another one. Getting deep cycle batteries to a large extent helps in the battery issue as they last longer than the regular wet cell (trailer battery) or even the SMF batteries.

Inverters are sold at ilabouchi. 1KVAs are very common.

The truth is "non-technical" people are usually misinformed about this inverter stuff.
I build and run inverters for personal use actually.
The most important part of the inverter like any other Electricity machine is the fuel which in this case is the battery tank. The next is the load. People are most likely to put all their hope on the inverter after they have spent so much on it considering the fact that electricity is such a failure in many parts of naija.
But this is where the disappointment comes in. And most people finally push the inverter aside and return to generators.

Inverters like generators are not meant for full time running because they require charging. So in Nigeria you actually need a generator or good supply of Nepa light (reasonable hours) to run an inverter successfully. else your inverter run time will keep reducing cos of low charging until its no longer reasonable. It may not mean your battery is bad if your run time is not as good as the first time , just that you are not putting back the power in the battery enough. Like filling your petrol tank in your generator.

The costs usually displayed by dealers in most cases are of the inverter alone. You will have to worry about isolated electrical lines if you want to have a fixed load not variable load on your inverter. The right kind of batteries (Deep cycle) and reasonable battery tank if you want to worry about extended hours of running, and this is usually not supported by the built in chargers in the inverter as they might be designed to charge at most 2 batteries in about 4 to 6hrs.
The solution to the charging problem and hence the run time is the solar panels which is no joke really. to make it efficient you need to collect a few of them, and considering the cost through some time.

Actually inverters are more economical in the long term if you inverst in about a 5kva or 10 to 20kva inverter, solar panels and a sizey battery tank. Periodic maintenance will be a total replacement of your battery tank in say 2yrs or so when your runtime reduces significantly and this is usually cheaper then the cost of petrol or diesel for an equivalent generator capacity, in the same period.
But trust me the cost will exceed N600,000.00 if you want it to make sense. No monthly servicing, no noise, no frequent trips to filling stations is what you will enjoy.
I will advise anyone willing to go into inverters as an option as a consumer to review options very well before starting to spend money. I will also advise that you build you battery tank in batches so you also replace them in batches this will reduce your periodic cost.
I will recommend small inverters about 1KVA for people running boutiques who only use mostly small fancy or fluorescent lighting and no need to power huge stuff if you can do without ACs. DVD shops, bookshops, electronics technicians who only test systems and use soldering irons.
Inverter for cold room use will be HUGE i guess.

Thanks for your contribution.

While I agree that some of your comments and advice made sense I think I disagree with the following comments as they would more than likely lead to misinformation and perhaps confusion.

Proper design of any backup application will take care of the appropriate charging algorithm for the battery bank. Only mass produced inverters with built in chargers have these problems as any inverter builder can build the charge to handle the battery bank.

You don't need 5KVA or 10 KVA to 20KVA for you to enjoy inverter backup systems. Solar panels must not be used either. Good deep cycle batteries can last for 5 years or more. At about N54,000.00 per 12V 200Ah deep cycle battery I do not think that replacing them every 2 years make sense as you will have to factor in the cost of disposal, purchases and installation each time you do that and these also cost money.

I have not used a generator in my office for over 5 years here in Lagos and I use 1.5KVA inverter. The last set of batteries I bought has seen over 2 years now and no drop in performance. Even though the state of power supply has really gone down in the last few months I still believe that a properly designed backup system would provide reasonable backup for most homes in Nigeria.

iukpe:

But trust me the cost will exceed N600,000.00 if you want it to make sense. No monthly servicing, no noise, no frequent trips to filling stations is what you will enjoy.

N600,000.00 seems high for the average Nigerian or even the average Nigerian that would want to embrace inverter backup. I have clients that don't mind spending more than N1M but these clients are very far in between.

N150,000.00 to under N400,000.00 is typical and with a good energy efficiency program you can see backup up to 2 days.

iukpe:

I will advise anyone willing to go into inverters as an option as a consumer to review options very well before starting to spend money. I will also advise that you build you battery tank in batches so you also replace them in batches this will reduce your periodic cost.

As stated earlier a good set of deep cycle batteries should last for up to 5 years before talking about replacements and this is based on proper battery bank sizing.

Many thanks for your time.

@ Afam,
Please can you advise me on which inverter to buy. I need one for home use and it will power a deep freezer, one LCD TV, two standing fan, one ceiling fan, one desktop computer and 3 laptops. Some of these appliance can be disconnected occasionally, to reduce the load on the inverter. I don't mind buying the 5KVA inverter to enjoy long hours of power. Please, i need to know the exact amount it will cost to purchase the inverter, battery and other required accessories, plus installation. Thanks for your time.

A 5kva inverter is capable of handling the appliances listed without any problems.

What about lighting points? They usually cannot be left out of the equation and don't under rate them.

You can get your inverter from any dealer that can offer you a reasonable warranty because basic maintenance or end user mistake may require repairs.

We build inverters locally for customers and have been doing so for over 5 years now and we offer 1 year full warranty.

The last time I used a generator in my office on Allen Avenue Ikeja was over 5 years ago.

You may see www.justalternativepower.com for more information

i have to say, u sound very conversant with most of these terms. i'm currently working on a minor project in the energy sector. I'd crave your assistance, cos lal i have is rudimentary knowledge. any input would be greatly appreciated.

Guys, even N150, 000 - N400, 000 is not a chicken change to the average Nigerian. How many Nigerians can afford N150,000 talk less of N 600,000.  The solutions you guys are talking about are for a selected few who have very deep pockets and that's not the solution to our needs as a country. We need to come up with pocket friendly alternatives to the epileptic power situation. If anyone can come up with cheaper solar based products that can take the place of PHCN and still allow people to keep some money in their pockets, then such investors or innovators would smile to their banks.

I am presently working on some of such research projects in collaboration with some foreign and local NGO's and you'll be amazed at the kind of products and projects we have been able to come up with. These are very simple and pocket friendly products.

We are presently looking forward to passing these skills which are a result of our research to small scale investors interested in effecting change and putting PHCN out of business while they smile to their banks.

If you're interested in joining us on this crusade, just send your enquiries to solarbizness@gmail.com

When it comes to generating electricity or storing electricity to be used as back up the technologies involved are not hidden, they are well known so talking about a research that could be pocket friendly as you put it and still replace PHCN may not really make sense.

Looking for cheap products and/or components that are usually mass produced based on design assumptions that may not hold water here in Nigeria is one thing, doing research on how to generate electricity is yet another.

Backup systems are usually cheaper than generating systems for the same loads.

Good batteries cost money, reliable inverters cost money, installation is usually not free. These are for typical backup systems.

For systems where you have to generate your own electricity you will still set aside money for what I have listed above apart from the core generating modules like solar panels and wind turbines.

Again, wanting to power everything in the house will not cost you the same as someone wanting to power essential loads as this will be usually cheaper.

I would like to warn anyone who will listen to carefully consider before believing sweetalkers who only want to get your money. I am an electronics engineer and have been using inverters for about 2 years. The points I make below should help you make your descisions:

1. Making use of inverters without at least 10hrs of PHCN is not worth it.
2. Inverters will not totally eliminate your need for generators.
3. If you must buy an inverter, buy an american spec. China / India products are mostly junk. Tripplitte is a good american brand.
4. Never use wetcell batteries, they die out within 3 months. Deep cycle batteries are the best but expensive, about N250 per AH
5. Solar panel are of 2 varieties mono and polycrystalline. The monocrystalline give a higher power output throughout the light spectrum.
6. Solar panel is still very expensive for now $3 per watt. You need at least N5m to power a 3 bedroom flat. A 180W panel costs about N140k
7. Before investing in inverter and solar panels, get an electrical engineer who knows what he is doin to help you with ur load sizing and cost.
8. With proper sizing and PHCN hours, you will get ur money's worth. With no PHCN please stick to your generators.
9. The bad news is that solar system is still very expnsive.
10. The good news is that there is rapid development in solar cell technologies. Thin film solar panel promises to cut cost to as low as 90cents/W

Good luck all

Please, make categorical statements on what you are sure of. Generalization don't make sense.

Granted, a lot of people have had bad stories to tell and I really don't pity most of them because when you present information that is factual some people ignore the information and go with what sounds the sweetest to the ears and when they have bad experiences they begin to generalize.

This is the same problem in the web development industry where people are constantly being ripped off by people who tell you want you want to hear as against what you should hear.


Now, to some of the points the poster stated that I disagree with

1. Making use of inverters without at least 10hrs of PHCN is not worth it.

--- This is a blanket statement that does not hold water in certain scenarios even though it does in some.

If I design a backup for say 3 days or 4 days and I require 8 - 10hrs of charging to recharge the battery bank assuming the battery bank is depleted then it means that the battery bank can do with less than 3 hours a day or 8 hours in the first day and 0 hours in the next 2 days before seeing another 3 - 8 hours on the next day.

My point is this - scenarios must be addressed as they come up. There is no "one size fits all" solution when it comes to inverter backup systems.

2. Inverters will not totally eliminate your need for generators.

--- Again, just like the 10 hrs issue it depends on so many things. My office is on Allen Avenue and the last time I used a generator in my officer was over 5 years ago and I cannot work in the office unless there is electricity because I am a software developer and must use the pc for me to be able to work.

So, my being able to work without a generator but with an inverter backup I setup is based on doing the right thing and correct analysis of the problem.

3. If you must buy an inverter, buy an american spec. China / India products are mostly junk. Tripplitte is a good american brand.

--- I disagree with you on this again for the following reasons

a) I have installed an imported inverter for a client just once in my about 6 years of building inverters locally and after that experience I refused to do so for anyone unless the person will sign that he will sort out any warranty issues with the original inverter manufacturer as I can only offer warranty for what I build as I know what is inside.

b) Majority of the problems come from improper charging algorithms because inverter technology itself (the changing of DC to AC) is a mature technology. We have had to open up imported inverters belonging to clients (not originally supplied by us), disconnected the in built charger, built our own charger and integrated it into the system and we have some of them working for over 3 years now.

c) The charging problem comes from basic design assumptions made in the respective countries you referenced and are usually mass produced based on common parameters that may not hold water down here in Nigeria.

4. Never use wetcell batteries, they die out within 3 months. Deep cycle batteries are the best but expensive, about N250 per AH

--- I agree that deep cycle batteries are well suited for inverter backup but I have heard from people using inverters with wet cell batteries that have worked for well over 1 year. The earliest inverter systems we built used wet cell batteries and most of them started having problems with the batteries from around 10 months and the problems were usually with the capacity to hold charge which directly affects the backup time.

10. The good news is that there is rapid development in solar cell technologies. Thin film solar panel promises to cut cost to as low as 90cents/W

--- I have followed the thin film solar panel trend and believe me most of the information are based on lab results that are usually unverified as quite a number of companies involved in this type of solar panel tend to treat every single information as intellectual property so we are forced to read and perhaps agree with what their engineers say which for all intent and purposes may be wrong.

The good thing about technology is that you don't hide it, if the progress being claimed is real then most of them should by coming out of production lines as we write these things here.


So, while I agree with some of the points you put down I disagree with the points I have reproduced and addressed in my post especially when statements that are not factual are used to discuss the alternative energy industry because I am involved and know the facts of the matter.

This is why I take out time to write articles to educate the end users to know more than enough to make good buying decisions when it comes to backup systems.

I have turned down many partnership proposals from inverter manufacturers in the countries you mentioned based on the fact that even their product catalogs have more than enough information to prove to them why their inverters will not perform well here in Nigeria.

If you visit www.justalternativepower.com (where I am the Chief technology Officer) you will see the difference in pricing on our inverters to the extent that we sell a 5kva 48vdc manual inverter for N220,000.00 and the automatic version for N260,000.00 even when imported 5kva inverters go for as low as N100,000.00 these days.

So, why would our locally built inverters be far more expensive than the imported counterparts when we can easily reduce the price to appear competitive and still make more money in the process? The reason is simple - We are not interested in the competition, we are only interested in building inverters that work with 1 year enforceable warranties where repairs or outright replacements are done at no cost whatsoever to the client.

However, the only problem we have is that our building process is slow and that we focus on modified sine wave inverters so you cannot use any sensitive medical equipment or laser based printers or copiers with our inverters.

Sorry for the long post but I believe I do not have any option than to correct misconceptions and wrong information as regards an industry I am doing my best to make right in spite of all the problems we have right now.

I presently do not use a generator even in my house even though I have one as I have been able to practice what I preach as regards energy efficiency which is the surest way to get a cost effective backup solution.

Any typographical errors are regretted and hopefully I will correct them when I have time to go through what I have put down on this subject.

Good points you have made Afam. The points I outlined are for the layman who is easily be ripped off. I tried as much as possible not to get into technical details

1. on the first point you suggested long PHCN hours is not necessary. Yes it is possible to charge your backup batteries within 3 hrs but check your facts fast charge limits the life span of batteries. The purpose of the system is justify cost on the long run. if you replace batteries every year its not worth it. If your inverter has 2 charge modes pls put it on the lower one to save your batteries.

2 you talked of using it in office at allen. I use it in my house where phcn is erratic. Obviously you dont use urs at night. the deeper you cycle ur battery i.e how low you deplete the charge will determine the time of recharge. The generator is always needed. Dont forget we are addressing nigeria peculiar situation.

3 I have tried india/ china products. The burn out easily and many of the are just cheap PWM circuits. Pure sine wave inverters are the best. I prefer american spec cos they pass so many standards before being approved for sale. B4 buying check the website for the approval body. I understand you are advocating ur business but it is possible to buy the right product without recourse to a repairman for upgrade and whatnots.

4 wet cell are designed for cranking e.g starting a motor car. the plate are not strong enough to withstand cycling they collapse easily wtihout frequent maintenace. Deep cycle on the other hand do not crank well. A 100AH deep cycle battery will not start ur car even if fully charged. The metal plates are very thick and and can be cycled many times over without any maintenance.


5 Thin film panel s are already in the market. The drawback is the efficiency which is still improving.

Hello Akanniade,

Thanks for your comments.

I will only try to correct some misunderstanding now you have stated your intention was not to generalize but to guide prospective inverter users.

Akanniade:

1. on the first point you suggested long PHCN hours is not necessary. Yes it is possible to charge your backup batteries within 3 hrs but check your facts fast charge limits the life span of batteries. The purpose of the system is justify cost on the long run. if you replace batteries every year its not worth it. If your inverter has 2 charge modes pls put it on the lower one to save your batteries.

I do not advocate for very fast charging. Our chargers irrespective of the size of the battery bank are built to recharge from 8 - 10hrs assuming a fully depleted battery bank because we build everything from scratch.

You may take a look at any of the articles below to know my position on charging as I have made it clear over and over again that you can kill a battery in either of two ways - slow/inadequate charging or fast/too fast charging.

Batteries just like anything that can hold charge must be charged appropriately and there is a formula for that.

Yes, I talked about my office on Allen and also talked about my house. If I have not used a generator for over 5 years in my office why would I agree with you that a generator is always needed?

It all boils down to proper planning and analysis of the inverter backup system. Unless of course an area has a problem with the transformer or that power outage runs into weeks at a time.

3 I have tried india/ china products. The burn out easily and many of the are just cheap PWM circuits. Pure sine wave inverters are the best. I prefer american spec cos they pass so many standards before being approved for sale. B4 buying check the website for the approval body. I understand you are advocating your business but it is possible to buy the right product without recourse to a repairman for upgrade and whatnots.

I understand your position about trying India/China products. I have not tried either and would not try any considering the fact that we build these inverters from scratch and provide one year full warranty. I use an inverter we built in my office so I do not have any reason to try one from any country because as stated earlier even from product catalogs and speifications I can tell a good inverter from one that will have problems along the way.

Point of correction, I am not advocating my business here but trying to make sure that Nigerians are equipped with facts on these products so they can avoid all avoidable problems.

As you can see I use my personal website on my signature because we cannot even handle the number of orders coming our way even when over 50% of them come from recommendations from people that are using them while the rest come from the web.

4 wet cell are designed for cranking e.g starting a motor car. the plate are not strong enough to withstand cycling they collapse easily wtihout frequent maintenace. Deep cycle on the other hand do not crank well. A 100AH deep cycle battery will not start your car even if fully charged. The metal plates are very thick and and can be cycled many times over without any maintenance.

Trust me my friend, I know what makes up a battery from cathode, anode to electrolytes and the different topologies. My statement or reference to wet cell batteries was to show that inspite of what we know about them some people are indeed using them and considering the cost they will continue to use them. I don't use them and I don't even agree to buy for my clients, I insist on deep cycle batteries if I must get batteries for them.

Akanniade:

5 Thin film panel s are already in the market. The drawback is the efficiency which is still improving.

Exactly, that drawback is the point I am making as it clearly shows that the promises and claims are only good enough for the labs, marketing and venture funds the companies behind them are always seeking.

Many thanks for your time. Enjoy the rest of the week.

Usually takes 7 days from payment date to build and deliver.

However, depending on the time of order we must confirm the delivery date to prospective client before payment is collected based on the work load.

The emphasis is on reliability and safety of unit, connected loads and personnel.

Hope this response answered your question.

Thanks . i will get in touch.

To get the best out of an inverter avoid the use of large transformer models, employ the use of transistorised verions usually from China. Also include an N70 Battery Chloride Exide. I usually run for 8hrs on a modified Computer UPS and car battery

Any idea where one can get genuine or original solar panels?

How much will a 10 - 20 KVA solar panel unit cost?

where can i buy 20watt solar module and it price

Hi,

For a 10kva out you will be looking @ around 7 million Naira, but my question is do you need as much as 10 kva,what are you intending to power? an energy efficiency plan can save you a lot, also by simply upgrading your appliances like Air Conditioners to energy efficient ones, you could be saving upto 50% of your energy output.

Let me know if we can be of any help, we offer a comprhensive consultancy service: Advice, supply/installation and after-care services.

Regards

I have 120watt solar panel for sale , if interested you can call me on 08035308511 or send me mail on justyinka23@yahoo.com
