Im confused on the wiring for the mppt. To work at maximum efficiency do all the interior lights and fridge have to be wired to the DC LOAD terminals on the controller? Or can they be wired to the batteries?
If someone has an inverter that gets wired to the batteries. So it seems like the DC LOAD terminals could be left empty? Barely learning but i think the mppt controller looks at the battery voltage and DC Load separately and reacts for max efficiency. Which makes me think i want to use the DC Load terminals. My current PWM controller does not have any DC Load terminals and of course no corresponding wires.
