Inverter are the basics need of our modern cities. We can not afford single hour without electricity. That’s why we use inverter. I have an apc inverter in starting month this inverter works well. But after that the capacity of apc inverter is decrease. Tge chase or stand of inverter is very week. Whe battery life in very average. My apc inverter last only one to two hour max. And that’s not ok. Others inverters in market last minimum 6 to 7 hr. Apc inverter is little bit cheaper but still not value money.
