I replaced a non-adjustable 2 stage solar controller (14.4v, 13.5 @ 90%), with a single stage adjustable voltage type. This is on my supplemental 140w system...The 300w main system uses a MPPT 14.4v single stage.
Lesson learned, mixing different type of charge controllers is not an efficient idea. Previously, at 90% charge the 2 stage controller would drop to 13.5v and cause the 2 panel 140w system to drop out. Like-kind controllers will now work in concert (140w + 300w) to enhance my race against the setting sun!
