my new 160w solar does not charge the BB battery

[waninae39]

i have a 2nd mmpt for a 2nd set of panels i wanted to install. As the panels are different make/model/size , i cant add them to the first mppt unless i put them all in series

i will swap out the 1st mppt with the 2nd mmpt and see if the fault continues
ill do that tonight or on the weekend; work gets in the way );
