I have a 300 watt power inverter and will install it permanently in the car. Now my question is: Does it have to be switched off when starting the car? The instructions say so, but I would prefer to switch is off only when the car is in the garage, because I also have a UPS and it would be slightly inconvinient to have to switch the both off when starting the car?
Has anyone done this, and what were the results?
P.S. I prefer to switch them both off each time than having a fried inverter
