Hello, I bought su-kam inverter and battery before 3 year ago and till their response is better.but I was faced problem after 2 month of the purchase date, problem is that after full charge of the battery their backup is very low means when we cut main supply inverter show battery low warning, then we complain on the shop they come my home and give me another inverter for use and my inverter is submit for repair and some day of repairing come home and set my original inverter and till date I never faced any problem with this inverter.
