Let’s explore why reverse flow protection is essential for grid-tied solar systems. Reverse power flow can destabilize the grid, especially in areas with high solar penetration. If too much power flows back into the grid at once, it can cause voltage fluctuations and pose a risk to other users.
What Is the Reverse Flow Protection of Photovoltaic Inverters? Reverse flow protection is a critical feature of photovoltaic (PV) inverters that ensures solar energy flows in the correct direction—away from the inverter to the home or grid, but never the other way around.
Inverters are designed to disconnect from the grid if reverse power flow is detected. This can happen if the grid experiences a power outage or if the solar power generation exceeds the consumption at the household level, pushing excess energy back into the grid. Learn more about grid disconnect features here 1.
#1 Use RPR (relay power relay) to isolate the PV plant from the grid by means of tripping the breaker or releasing the contactor if there is any reverse power detected. #2 Use an Export limiter to limit the power generation of the grid-tie solar inverter concerning the power required by the load. #3 Use of PLC as an export limiter.
This mismatch has not been a problem until now. Inverters have assumed that the grid is strong and will provide a stable and clean voltage and that they are able to inject real power into the grid without undue impact on its operation. The electric power grid is in transition.
