9 units of 40AH batteries would mean 108Volts/360AH.

Can you tell me how much you purchased the inverter, how long it takes to charge from empty to fully charged and how long it lasts at full load from fully charged to completely discharged?

I need all these info in order to make a good decision on what to buy.

@Area, I'll give u a call by morning.

@coola: That's a nice one.

You are using 9 batteries for your inverter? Wow, that must carry ALL the load in your house.

I started using an inverter in 2002, though a small one(0.5KVA) with a 200 AH trailer battery. It powers my lights(energy saving bulbs), electronics(21" TV and medium sized home theatre) and 1 fan. Can power these for 24 hours before battery fully discharges. Normally use between 6pm and 11:45pm, so can go 4 days. Battery lifespan is 18 months because of over charging.
Had to abandon inverter about a year ago when NEPA went AWOL, so there was rarely power to even charge the battery.

I heard there are some that use solar panels to charge the inverter all day long, which eliminates the need for NEPA.
@brym, how much does that kind of ur inverter cost now?

Not necessarily. Most inverters operate on either 12 or 24 volts. So if Coola is using 9units of 12v batteries, then the batteries are connected in parallel so the output voltage will be 12volts/360AH

@mamba: The guy who assembled mine no longer makes 0.5kva models but models from 1kva to 5kva. The price starts from 30k for the 1kva. I bought mine for about 12k in 2002.

@Mamba... lucky you! Everything you need for an inverter on one page.

See Areafada's picture for the kind inverter I have (Made in China! Too )
See Bryms last two posts on what I use my inverter for and approximate price.
See Amby's post on how I connected my 9 batteries (in parallel, so the capacity is greatly expanded and the voltage remains 12v).

The fellow I bought mine for sells 500w for 10k and 1kw for 20k.

Theoretically, it takes 12 hours to fully charge. But if you get 4-6hours of NEPA daily, your batteries may never run down.

Two men, one American and an Indian were sitting in a bar drinking shot after shot.

The Indian man said to the American, "You know my parents are forcing me to get married to this so called homely girl from a village whom I haven't even met once." We call this arranged marriage in my country.

I don't want to marry a woman whom I don't love... I told them that openly
and now have a hell lot of family problems."
The American said, talking about love and marriages...
I'll tell you my interesting story.
I married a widow whom I deeply loved and dated for 3 years. "After a couple of years, my father fell in love with my step-daughter and so my father became my son-in-law and I became my father's father-in-law.
Legally now my step-daughter is my mother and my wife my grandmother. More
problems occurred when I had a son. My son is my father's brother and so he
is my uncle. Situations turned worse when my father had a son. Now my
father's son i.e. my brother is my grandson.
Ultimately, I have become my own grand father and I am my own grandson.
And you say you have family problems? The Indian man fainted... . . .

Has anyone else tried video calling with his/her spouse? Or tried it just for fun? If I recall correctly, only one person has done it. I find it surprising. So I wonder... WHY?
A] Spouse/Friends have no 3G phone?
B] Problem with the settings?
C] High tariffs?
D] No interest?

A] Spouse/Friends have no 3G phone? My wife is on another network zain is it possible to make video call to her? She uses N95.

B] Problem with the settings? I don't have problem with that, I've gotten my video call settings correct.

C] High tariffs? It's might b expensive, but most of my calls r business calls n i don't need to see the person's face, i just need answers to question like, has to product arrived? have u brought the stuff? please pay the money into the account? i'll deliver the stuffs, etc


D] No interest? I'm interested, i want to even see 3G video call at work. what i'm using 3G for in my case, on mtn platform is high speed browsing.
