Compatibility depends on the power station's supported solar input voltage, current, connector type, and maximum solar charging wattage. The PM400 PLUS specifications list 39.6V ±5% maximum power voltage and 47.52V ±5% open-circuit voltage. Confirm that the receiving device supports these electrical characteristics before connecting the panel.

Can the OSCAL PM400 PLUS provide backup power during an outage?

It can contribute to a compatible solar backup system, but the panel alone cannot power appliances directly as a complete backup solution. A suitable power station or other compatible equipment may be needed to regulate, store, or convert the electricity. The size of the overall system should reflect the appliances you want to operate and how long you need to run them.

What does the panel's 22.7% conversion efficiency mean?

The stated conversion efficiency of at least 22.7% describes the proportion of incident solar energy converted into electrical energy under the relevant test conditions. It is useful when comparing panels, but it does not mean the panel will continuously operate at 22.7% of its rated output in every environment. Real-world output varies with sunlight and operating conditions.

What is the difference between maximum power voltage and open-circuit voltage?

Maximum power voltage, listed as 39.6V ±5%, is the voltage associated with the panel's rated maximum-power operating point. Open-circuit voltage, listed as 47.52V ±5%, is measured when the panel is not connected to a load. Both figures matter when checking compatibility with a solar power station or charge controller.

 What do maximum power current and short-circuit current mean?

The supplied specifications list maximum power current at 10.1A ±5% and short-circuit current at 11.11A ±5%.
