Hello, we do have a 630Ah AGM Lifeline Bank and we charge it with two mppt controller. 1 x 75/15 and 1x100/50
Whlie the mppt chargers have the exact same settings the 75/15 always goes in absorption/float very fast... shouldn’t go the two controllers in parallel in the different modes ?
Do the two controller need different settings ?
As lifeline advices us to charge with different voltages we adjusted the abs. and float voltage accordingly For the two controller.
