Hello everyone, I would like to purchase a UPS to operate a large garage door motor on a multi-unit building. The motor is a 120V AC 370 w load. I am told that 2 things need to be considered: the motor requires a pure sine wave and the in-rush current of the motor must be dealt with while on battery operation. I believe one can purchase a pure sine wave output UPS and if I could estimate the motor in-rush current then I could buy a UPS big enough say 2200 KVA to handle the in-rush current, is my reasoning correct?
2. How can I estimate the in-rush current?
Thanks,
Jacques
