mecussey:

AFAM, 2500 is 2.5kva that is 2500va. and 200 is the assumed load, and 2500/200 is not 20 but something above 20. But considering losses, like heat, eddy current, histerises and resistance you will have like 20. Therefore, if you buy 2.5kva inverter, what you actually bought is 2KVA. Let me know if you don't understand

you are missing the point. the inverter is probably 3kva and the manufacturers have designated it as 2.5 kva because of the losses. its unscrupulous nigerians who are unconcerned about creating a brand name who would go about labelling an inverter with 2.0 kva output as 2.5 kva.

I should let you know if I don't understand abi? Ok

1. 2500/200 is not something above 20, it is 12.5

2. A 2.5kva is not 2.0kva, only God knows where you got this idea from

3. Losses do not increase backup time but decreases it.

My dear, be careful how you mislead Nigerians on issues like this, better still take time to understand how these things work.

We build inverters from scratch, my office has never used a generator for more than 3 years now and we have offices and homes with up to 4 days backup in place.

AFAM, you are correct, 2500/200 is 12.5 it was a mistake therefore you will have a run time of about 10hrs, but u are wrong, a 2.5kva inverter must result to something less than that on load, probably 2KVA. Research

Why do you prefer to show the world that you are not up to speed on this inverter stuff.

I should research abi? You are always asking people to do what you should have done which will make life easier for you.

There is something called efficiency maybe that is what you have not been able to relate with your positions.

imatejammer,

Please can I have the name and the number of the chap who instal the indicator on yr inverter battery. U can reach me on 08033538717, 7632113 or muyioye@yahoo.com.

thanks

Folks,
How much power is needed to sufficiently handle 3 AC's, 1 refrigerator, 1 deep freezer 3 desktop computers, lighting fans and other household appliances( Pressing iron,microwave) etc using an inverter?

In other words, what KW rating on an inverter should I buy for a 3 bedroom bungalow with the aforementioned load?

Thanks for your responses.

Inverter back up systems are not cost effective for scenarios like this one trust me.

Backup is backup and not a replacement so unless you have unlimited source of cash and you don't mind spending a lot of money removing the 3 AC's will be a good place to start from if you really need an inverter backup system.

hello Afam, but the cost of Inverters are too much. What can be causing that??

The components used in building them especially for companies that will offer serious warranties for their inverters.

we have one in our office and its expensive.so can one get cheap ones for homes ?? like less than 1Kva ??

Mr Matthias,

I want to believe that we have exchanged quite a number of emails on this issue so asking me questions that have been previously answered isn't right or proper.

YES I AM VERY INTERESTED TO BE ONE OF YOUR DISTRIBUTORS. THOUGH, I BASED IN COMPUTER VILLAGE IKEJA AND I HAVE ANOTHER BRANCH IN ABUJA. FRANKLY, I HAVE SOME CUSTOMERS THAT ARE ALWAYS ASKING ABOUT INVERTERS BOTH HERE IN LAGOS AND ABUJA. SO I WANT TO KNOW WHAT IT TAKES TO BECOME YOUR DISTRIBUTOR. YOU CAN CALL ME AT 08033924627, VICTOR. ANAYO.
THANKS.

I manage a cybercafe and I'm having problems with regular UPS. Which of your inverters will you recommend for a Cafe with about 15 computers, 1 laserjet printer, 1 deskjet printer, 2 ceiling fans.

I plan to get an inverter in a few days to power, LCD, Dstv,Laptop and about 6 energy bulbs. I was recommended to a chap who said I should get 1.5Kva and his price, 170K it includes installation, 2 batteries, stabilizers.

Do I go ahead, and is there a brand name i should look out for.

Thanks all

Strat that is too much men, 170k? why not go for solar, any way 6 energy bulbs will consume nothing less than 2kva, therefore, with ur electronics, u need 3kva inverter which is about N33,000 but Simba said he will give u 23000. Two 200AH batteries connected in parallell, which is about 50,000, total should be arround 90-100k with labour, and u will have a runtime of about 7-10hrs. Pretty good.

Any warranty on any imported inverter is useless because if something goes wrong the cost of shipping to the manufacturer and returning same to the user even within the warranty period in some cases will be more than the cost of the inverter.

Look for inverters with support you can rely upon should something go wrong.

1.5kva 24VDC system can handle the loads.

You do not need a 3 kva inverter.

N170,000.00 is on the high side but again price is really not the most important factor in inverter backup systems.

Afam
i'm looking to upgrade my existing inverter installation, and i have a question

currently, i use a 1.4kva inverter and two 100ah wet cell batteries
is it a problem if i augument with two more 150/200 ah wet cells?

or must all batteries used have the same amperage?

can one combone dry cell and wet cell?

thanks in advance

It is not a good idea to mix batteries of different age.

Wet cell batteries don't last because they are not built with thick plates so they cannot without frequent charging and discharging cycles, get deep cycle batteries.

Doubling your battery bank without paying attention to the charging algorithm may not increase your backup time as your battery bank may never be fully charged from the day you hook everything up.

Who can explain the difference between a UPS and a DC inverter, 600VA inverter costs more than 600VA UPS even without batteries. For me, I don't see any difference between these two equipment, just that people don't understand it. UPS is sine wave like wise some inverters so what made the difference. Lately Simba have started selling 1.4kva inverter for 10000 Naira only, looking good, I know in future it will even be less than that. It is as simple as to construct a 50HZ ossillator and amplify. The major cost of these inverters are the transformer, transistor and battery. By the time china will go into mass production, I think we will get it as cheep as stabilizers

@mecussey,

Can you do us a favor by not saying things you don't understand?

1. There is a huge difference between inverter and UPS

2. UPS in most cases are modified sine wave, very few are true sine wave

3. The battery is not a component of inverter

4. UPS come with integrated batteries, you don't get UPS without the battery inside

AFAM, why do u like to attack without any point

you said UPS is modified sine wave, only few are true sine wave. Therefore we have modified and true sinewave in ups, so what are inverters. Inverters also have modified sine true and square wave, depending on what you have. So what is the difference

You said Battery is not a component of an inverter, I agree, but 600va ups come with it at the cost of 6000 to 10000, now tell me where u will see that kind of inverter

I posted, "Who can explain the difference between a UPS and a DC inverter, 600VA inverter costs more than 600VA UPS even without batteries

You said, "UPS in most cases are modified sine wave, very few are true sine wave". Yes, likewise inverters, so what is the difference

You also said," UPS come with integrated batteries, you don't get UPS without the battery inside"

From ur answers, what is ur line of argument because u didnt answer my question

@Steroid101,

I presume you are mecussey, were you banned?

You made a post on the webmaster section about not making money online and wondering if you have wasted money browsing the internet and I did post a reply advising that you must be ready to provide correct and relevant information before anyone can trust you with his/her money online.

UPS and inverters are different.

UPS involves a 3 stage conversion process and cost more because basically all the components are working all the time.

Inverters can be manual type or automatic and even with the automatic all the components don't work all the time, when you have regular power the inverter unit simply transfers the regular power to the loads but with UPS the loads never see the regular power.

Now, your inability to understand the differences I pointed out in the post before this one is certainly your own wahala not mine that is why I have not bothered to revisit your comments on them.

I only provided further information on the difference between the 2.

Good night.

Afam, thanks a lot your contribution has enlightened me a great deal, however I would not like to go to the market to pick up inverter, battery, stabilizer and look for someone to install and then after sales service, I have had enough of that with my generator.

I need a company that can do all this and just bill be and the only price have gotten is 170K, can I get the same package for less? if so help me send the contact ASAP.

We build inverters and offer 1 year full warranty. We recommend batteries or get them at N2,000.00 extra per battery.

We install inverters for clients especially automatic ones.

However, we cannot take any orders until the first week of April due to the high number of demands and we don't want to fail on scheduled deliveries.

Afam baba, you're the man.
Thanks for contributing so much to the thread. I intead buying an inverter soon but am sure the after sale services is more important that just buying so i intend buying from you guys at JAP but i ned you to clarify someting. Is your dry cell batteries the same as deep cycle. Cos i hear deep cycle are the best. Please reply as soon as possible, i will like you to help out with some calculations My email is cdude65@yahoo.com

Dry cell batteries may or may not be deep cycle batteries.

Deep cycle batteries are manufactured with thick plates and they can withstand frequent charging and discharging cycles without harming the batteries.

We don't sell batteries, however the best (based on availability) that I can recommend now is from Asia (www.sunnyway-battery.com). The importer sells for N45k but if I am to get it for you I will charge you N48k due to the cost of transportation from his base (Ojo) to my office at Ikeja.

12V 200Ah batteries with 10years design life that means you will use the batteries for quite a while before having any problems whatsoever.

Just to help you out. If a battery is rated at say 12V, 200AH, it means that if you have a load that takes 200 amps, the battery will last 1hour or After 1hr, the charge of the battery will drop to about 90% which is the recommended lowest voltage for a normal batteries.

Deep Cycle Batteries can be drained to 50% of the maximum voltage (in this case 12V) without any damages to the battery.

If you are using a Deep cycle battery, you have a chance to drain your batteries deeper without any problem. You may have an advantage if you if you have an inverter that has an adjustable low cut-off.
