Hi! I have a remote cottage and recently put in an electric boat lift. 1 Hp motor runs on 120v. It’s all great, until we had a 2 day power outage and I could not get the boat down off the lift and couldn’t leave.
I don’t want to have to purchase a dedicated gas generator to have down at the dock for these rare occasions, but from a safety aspect, I am thinking I should have something.
Would perhaps a 12 volt battery (or series of batteries) with an inverter be enough to start the lift motor. It only needs to run for about 3-4 minutes to get the boat down. I think it is just getting enough power to get the motor started that is the big draw on amps or watts (not sure the electrical terminology)
