I have an motorhome with 4x 250 watt solar panels (1000 watts total) in parallel feeding a victron 50 amp (700 watt) mppt controller to charge the lithium house batteries. Since I potentially have an extra 300 watts, I was thinking of adding another 10 or 15 amps mppt charge contoller to the same solar array to charge the lead acid starting batteries. Would there be any problem doing so?
EDIT: Hi @johnwbeem, as pointed out by astute others, I misread your post in my original response - I thought you were adding a second controller with a second set of panels, which would be fine - a second controller to the same set of panels, however, will not work. Sorry for the confusion!
Really? It was my understanding you can't connect 2 MPPT's to the same array of panels.
Good catch, both, I did indeed misread the original post. Too many simultaneous support conversations going on at the same time. Edited to reflect, thanks for catching my error!
