Totally wastage of money.i think its not good to by this inverter.it has not good bettery life and not good to take up the power of electricity if the electricity usually goes very frequently.so its not good for those who facing problems of frequent power cuts or load shedding.not recommendable.its not easy to maintain this inverter and its problamatic issues. so I don’t think it is benifitial to buy it.because of its poor performance.
