Hi - I have a Speck BADU Smart Solar pool pump, 72V 750W running off 2 x 550W panels. I want to use the Utility fallback incase of bad weather. I can find an AC 220V to DC 72V 10A converter but need a DC Auto changeover switch. Has anyone done this that can give me direction?
Utility 220v converted to 72V.
72V from panels and 72V from utility into Auto Changeover???
