Our RV trailer has 2, 170A Zamp solar panels on the roof run through a Zamp PWM controller to 2, 100AH Victron lithium batteries. I want to switch the controller to an MPPT Victron. Zamp reverses the polarity on their stuff. Does that mean I simply switch the negative and positive wires from the ZAMP panels to the Victron controller? I don't want expensive stuff to be damaged!
