So when i look at this manual it says "-" instead of 1 or 2 max for 60 cell Voc<38v (24v) under Tracer2206AN. Does that mean; dont even try connecting a 60 cell 24v + panel?
I probably overstated it as "not as effectively," but the MPPT may not perform as well as it would with a 72 cell panel. This would occur as the battery hits peak voltage and starts reducing power anyway.
