I setup this ups and inverter for my village home. Some disadvantages are come with this brand.This has a major disadvantage of no auto restart.
This occur most of the appliances. It is quite common to have some machines like mixer grinders on ups.
But if you change the mode than this solve for high voltage.When overloaded, it gets reset. even after removal of load, the inverter doesn’t get power up automatically. This means everytime reset this manually. It is an irritating process. It doesn’t appear like generating pure sign wave since the fans makes humming noise. This happen nearly every time. After an year the product started giving constant problems. The service is so pathetic that even after several requests, he could not get the new board. The inverter doesn’t have self protection from socks. It gets spoiled on every lighting and also it spoils all electronic equipment at home. Overall, this is the worst product and service.
