Dual Battery

A dual battery solar charge controller (or regulator) charges two batteries from one solar setup, so you don’t need a separate solar system for each. It suits setups with two batteries, such as a house battery and a starter battery. Our 10A 12V/24V dual battery controller handles up to 120W of panels on 12V or 270W on 24V.
