Very very good for 2 bhk house. And backup is also great. Totally soundless. I like the overload fuse. If we by mistake connect a heavy load on it then the fuse blow. This is good, the inverter saves itself from damaging. Nice one.
Very good product at this price range, I got it for Rs.2630. I am using this inverter with Exide 150ah battery. Working effectively. Thing you should kept in mind is mentioned below, 1: it's a square wave inverter so it's making humming noise while using fan during power cut.
2: It's 600VA inverter that means you can connect upto 580Watt of load. For example You can use 4 fans and 4 CFL bulbs 1 Led Tv.
3: For the above mentioned Devices we can use each battery as follows.
