4 FAQs about What does negative inverter power mean

What happens if a power factor is negative?

In this case, if the reactive part of the consuming power is more capacitive than inductive. The negative Power Factor causes the terminal voltage across the load to rise above its open circuit value. This may damage the voltage-sensitive load. A negative power factor can damage the power-generating devices such as solar panels, generators, etc.

Why is my PV inverter generating negative power at night?

This will generally result in negative power or a very low power factor. In some cases, you may see negative power readings from a PV inverter at night. See Non-Zero Nighttime PV Power Generation for more information. Reverse the CT on the wire being monitored. Swap the white and black wires at the WattNode.

Why does my PV inverter have a low power factor?

For example, suppose the CTs are shifted by one phase, so that instead of monitoring phases A, B, and C (in that order), the CTs are on B, C, and A. This will generally result in negative power or a very low power factor. In some cases, you may see negative power readings from a PV inverter at night.

Is solar power a positive or negative source?

For example, in most buildings, power from the grid, is considered "import" (positive), and power that is pushed to the grid is "export" (negative). However, in a solar inverter application, the inverter may be considered the source, and it is desirable for its power delivered to be considered positive.
