I am using it since past 2 years. No issues yet.
Where I live there is very much of tension of load shutting.
The inverter must here. From last two years, we don’t have any problem of load shutting becoz of my inverter which give us maximum of 6 hrs backup with 3 tube lights 4 cfl and 3 fans. Sometimes my pc also.Just we care sometimes for water of battery otherwise its great inverter.
