Hello friends, I bought this inviter for 3 month ago. This inverter I bought for my home. When I bought this inverter, the dealer assured me 1 year. 3 month ago inverter got worse, I called the dealer that the inverter got worse. The inverter battery got worse. The dealer gave the old battery saddle a new battery. There was a problem of the battery again in ten days. The inverter is bad. According to me If you want to buy an inverter, buy a good company. My opinion is bad with this inverter.
