Hey guys, i intend getting a solar system soon and i intend to start small and then upgrade cos if i wait to start BIG i might never get the inverter.

My Calculated WAT usage on the appliances i intend to use is just 280W. I don't intend to start with Solar Panel yet but will upgrade later.

My question is: On NEPA light or Generator (I use a 2.8Kva gen), How long will it take to fully charge one 12V 200AH battery with Electricity or Generator with a good Inverter.

I will be very grateful for your answers.

I don't know

It depends on the charging current of the inverter, most Indian inverter do 13amps for their charging current, if u deplete the ba3, lets say u use 70% worth of juice. It could take u abt 10 to 12hrs to charge fully.
Best thing is to get a smart external charger alongside it, so u can charge full in abt 4 to 5hrs.

Call/whatapp 08117398294 for purchase of ur inverter, agm batteries, solar panels and installation.

More answers to my questions please

To be honest with you, you can't use a 280 watts load on a single 200ah ,12v battery for long ,that battery will quickly RIP. Being on solar and inverter system for longevity of battery life would mean : a so
at TV ( 15-20 watt) ,solar standing or ceiling fan 15(watts), cfl or led bulbs (10-20 watts) , solar freezer ( last I saw was 250k), solar iron 6.5k,radio (around 15 watts). Even ,I'd advise you to use a smaller laptop or tablet( less than 40 watts). Don't be deceived by anybody telling you otherwise because they want to sell their products. Unless you are buoyant enough ,I'd advise a separate wiring for for your inverter to inverter powered devices in your place. Don't buy car or trailer battery ,they can't last you more than 3-4 months on heavy cycle use. I also started small with a single battery ,but minimal power loading 2013. Also, check "solar as a complement to FTA on nairaland". Now back to your question, how long to charge a 200ah,12v battery, it all depends on the charger you're using and to which voltage you last consumed your battery. Try not to consume your battery below 12.4 volts often for longevity of battery life.For a 20 amp charger , to charge from like say 12.2 v to 13.1 or so volts should safely be 12 to 14or 15 hours for a good battery. Check those guys I mentioned on nairaland and ask questions there. Goodluck!

Hi bro.. So, I have a smart TV with 75W, a laptop of 65W. I will surely need a a fan but will be looking for solar fan not the ones I'm using now.

So, with these I mentioned above, I can't use 200ah battery?

With a UPS 650WATTS you can hookup an external 12V fan and a 200amps inverter battery to run the load you proposed for straight 8 hours.
I do this on a daily with the lowest budget you can think of.
