I'm trying to set up a back-up power supply for our sump pump and had a quick question about the configuration. I have a deep cycle battery, trickle charger, inverter & relay. I'm confident the electrical tolerances are correct, but I wanted to confirm I had the connection order correct?
Outlet=> relay => trickle charger => deep cycle battery => inverter => sump pump.
Any help would be greatly appreciated... Thank you!
