Runtime = usable energy ÷ average draw. We count 85% of the rated 1,548 Wh as usable (1,316 Wh) to cover inverter and DC conversion losses. Fridges and freezers are averaged over their compressor cycle. An appliance runs only if its running watts fit the 1,500 W inverter and its start-up surge fits the 3,000 W surge rating. Wattages come from our appliance wattage table; try your own mix in the runtime calculator.

Recharge time is from empty with one panel in full sun: 1,548 Wh ÷ the lower of75% of the panel's rating or the station's solar input limit. A panel rated above the input limit is safe as long as its Voc fits, because the station only draws what it can take. MC4 panels need a standard MC4 adapter cable, which many stations include. Wiring two panels in series doubles the Voc, so check the total against the voltage window. Try any pairing in the solar panel matcher.
