I have this inverter in home from past 4 years.so I can share a proper review on it.
Initially when dy gt it home I found it was very bulgy and huge.v had to make a separate place for it.
Whn v started using it.it just gave amazing results.it charges thee battery whn power is on and once power goes off.it provides the electricity supply to wherever the connection is given.during summer v have huge power cuts in my place for about weeks vt nly 1 hr power a day.dt time it really helps a lot.once charged it lasts for about 2 days.including turn lights fans, tv and computer .
It is highly durable and not damaged evn a bit until now.and it very easy to use.u shud gv the connection during installation it automatically does wrk whn power goes off.
Yes, the liquid inside finishes off once in 2 years u need to refill it.it is nothng but distilled water which is so affordable and cheap.
So I suggest u all to try this inverter .
