This is a pretty good inverter. It can connect two batteries at a same time. I have this inverter in my house from nearly 5 years and don't face any problem till date and working suoerfine. I it have smart charging. It also have low battery indicator which make us easy to know about the battery level which protect from any failure. It also have overload as well as low power indicator which also helps to protect any failure.
I think if you want good inverter then you should go for this. This will provide good value for money.
