Hello friend, I’m Shivam. Today I want to share my personal experience about this product. So basically I will give you guys an honest opinion regarding about this inverter, actually I have been using this inverter for an year ago, and its happen to week day by day its not beacause of the ups, it is because of the battery but the current paas through UPS. So I will blame both in my case because I had a hard time with this product and the place where I am living in its very inregural to be honest and when lights are gone it only stays for just 20 or 30 minutes and shuts down. So in my opinion buy some other inverters or battery.
