Utl sun pack 1025 pure sine wave inverter is not a good product. My uncle purchased it in last year. He always unhappy with this inverter. Their charging capacity is worst, it takes more time to charge battery than another inverter . If you buy it you are totally wasting your money
Company says their backup time is in 6 hours but it takes more than 8 hours. Their service is also not good, if you call to customer care it will take more time to complete his service.
Please guys don't waste your money .
