Press the appropriate power button to reset the circuit. Let the fans run a few minutes, then reduce the load and try again.8
High TemperatureThe battery has become too warm and the overheating alarm icon appears on the panel.Remove the load and let the unit cool down, or use it in a cooler environment if possible. Press the appropriate power button to reset the circuit. Let the fans run a few minutes, then reduce the load and try again.11
OverloadToo much power is being drawn from the power station. It cuts off power to protect itself and the battery, and the overload alarm icon appears on the display.Disconnect the load and press the appropriate power button on the panel to reset the circuit.11

FAQ

How long will the WEN PP300i run a refrigerator?

About 5 hours for a typical 120 W refrigerator that runs 35 % of the time, after inverter and depth-of-discharge losses.

Can the WEN PP300i start a sump pump or well pump?

Starting surge matters more than running watts: this unit is rated 600 W peak. That is below a typical 1/2 HP sump pump start (about 2150 W); check your pump label. Use the calculator with your exact pump.
