Check the 22.2V Voc and 22.9A Isc against the controller's PV-input limits, then confirm its permitted array wattage and expected battery-side charging current for your battery voltage. The controller must also have the correct charge profile for lithium LiFePO4, AGM, gel or your specific battery chemistry.\u003c\/p\u003e \u003cp\u003eFor portable power stations, verify the unit's solar-input voltage, current, connector and polarity limits before connecting.

Runtime depends on fridge consumption, battery capacity, other loads, weather and total solar harvested each day.\u003c\/p\u003e \u003ch3\u003eCan I use an MPPT controller instead of PWM?\u003c\/h3\u003e \u003cp\u003eA compatible MPPT controller can be used when its PV-input and battery-output limits suit this panel and battery bank.
