I have heard that one can use external Intelligent charger to charge inverter batteries faster. How true is its effectiveness to REDUCE charging time and are there DISADVANTAGES to its use? I have a friend who uses a 5kv inverter and 8 batts but his area only gets 2-3hrs of Nepa daily which is not enough to charge his eight 200ah batteries fully and he needs my advice. Though he has a big generator which can charge the batts but at a higher cost(diesel), hence the thought for this ext charger. Users and gurus in the house pls advise.

Please could anyone advise if a PRAG GED GEL BATTERY 12v 200ah is a good battery like e.g. Zenith battery?

@excell all good but prefernce on exprnc & fund zenith, rita, sukam. pls note adequate charging contrbute to batr lifespan

@specco extnal charger are normly used. if it s me in this situatn i wl think of solar. it is all about cost & value for money. charge low, too high & fast, loss batr. is d setup 48v or 96v?

Pls house, where can i get a sound inverter technician dat can help me repair a 50kva inverter dat does not do automatic switch wen there is a power cut? Urgent, pls.

Pls guys i want to know
-if 800va inverter can charge 100/200 ah battery using smallest tiger generator.
-at a constant 150watts load will new 200ah battery charge and discharge using 800va in-built charger
thanks.

Hello house, I have been using a 1000w modified sine wave inverter(ST) and a 200ah battery to power my old CRT Television set but now I want to upgrade to an LED 32'' television set. I want to know if the same MODIFIED sine wave inverter can power the LED tv without problems or must I get a pure sine wave inverter for it? Please I need advice on this before I buy the flatscreen set.

Sure you can.You only need pure sine wave for highly sensitive equipments like medical and diagnostic stuff.

Unless you have a lot to throw around, LED technology LCD work well on modifine sine wave, and it save energy well well

Smallest tiger generator charge your battries at a snail speed, but if you have a good charger, you will be surprise that the same Tiger. Generator can still deliver 15amp. But on a normal day with inverter charger you get around 5amp which is too small

Yea, thanks Omotoda and femiolorun. I was only being cautious because I have heard some unconfirmed stories about the danger of using modified sine wave inverter to power some electronics. I thank you for your answer as I look forward to more confirmations from other users. Thanks

If you can afford the sine wave, I advise you to change to it. I have an uninvestigated report from one of my clients about his LED TV which kept blowing up after he replaced his LCD. The LCD never had issue all the while.

hope he is not using it with generator if is mercury

JUO: hope he is not using it with generator if is mercury

Could you expalin this further?I use a mercury 2.4kva inverter and use generator with it.

try it with 1200w and get back to me.
N.B i don't think mercury has any 2.4kva inverter. that thing is label

I thank all the contributors to my request for advice and from the responses I think I can now make an informed decision.

If you have a point to explain I think you should just educate us.DoI have to go buy a mercury inverter 1200watts just to understand ur point?

And mercury has a 2.4kva(1440watts) inverter which I use to power my fridge and freezer at the same time.

you probably discovered is 1440watts

JUO: try it with 1200w and get back to me.

what was your experience with d 1200w mercury and generator? I would really like to know, thanks

@femi thanks my guy. I appreciate.

Wonderfull thread. I had a little issue.
I use 3.5KVA with four batteries in my 3 bedroom flat. I barely use generator as we have over 12-hour electricity daily.
I use only NEPA to charge my batteries.
Recently I noticed that whenever i change to inverter it will trip off unless i reduce loads drastically.
I then observed my batteries and i noticed that one of them is bad, It has a kind of a cut on top and it leaks acid little.
MY QUESTION IS?
1.Can I disconnect the spoilt battery and connect only 3 batteries to the inverter(at the interim)?
2. Do i need to change the whole batteries or only the spoilt one?
3. What could be the cause of this anomaly? The batteriess are just about 3 months old(the seller advised me to buy used 'belgium' batteries that there are so many fake new batteries)

@ife analysis of d setup necessary. brand of inverter? d broken batr need change and others chkd. you cant connect 3batr setup lkly 48v

any shortcut in inverter/solar setup alway hv its conseqcs. this s d challenge n d north. early this yr my friend nearly got his house burnt frm cheaper alternatv

How long have you been using the batteries? If they are over a year I suggest you just change all Four.You can however have them tested. But it is alwatys best practice to change all batteries once one is bad to prevent imbalance in ampere distribution.

The batteries are just 4 months old

It is most likely you bought fake batteries.Have you used the inverter with other batteries prior to changing to the present set.If it is your initial set up then most likely the batteries are fake. A lot of dubious people by weak deep cycle batteries open dem up neatly, fill them with acidn close them up and sell them as new.

It is advisable you have all four batteries changed with reputable one, preferably trusted brands.
