Sungrow Zero Export Device
On-gird solar power (PV) plant generates excess power when the connected load is lesser than the power generated by the solar power plant (Power generation > Power required).
This excess power is synchronized with grid power hence it can revere the power flow.
In simple words, power will flow from the PV plant owner’s home to the connected grid [when Solar power generation > Power required by connected load].
