6 FAQs about [Photovoltaic inverter anti-backflow installation]
How does an inverter achieve anti-backflow?
Upon detecting current flow towards the grid, the inverter will reduce its output power until the countercurrent is eliminated, thereby achieving anti-backflow. It is important to note that the CT and meter themselves do not have anti-backflow capabilities; they simply collect data to enable the inverter to adjust its output accordingly.
What is reverse power relay (RPR) for solar?
Reverse power relay (RPR) for solar is used to eliminate any power reverse back to gird from an on-grid (grid-tie) PV power plant to the grid or to the generator by tripping either on-grid solar inverter or breaker or any contactor depending upon the type of power distribution and a control circuit.
How to install an inverter?

How to use a grid-tie solar inverter?
#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.
Who can use a Growatt inverter?
Persons with limited physical or mental abilities may only work installation and maintenance personnel; with the Growatt inverter following proper instruction and under 6.The use of this machine for grid-connected power generation requires constant supervision.
What happens if a partial inverter is installed?
Another opportunity for back feed to occur in such partial installs is if the inverter trips. In such a case, the voltage on the DC bus will collapse, but the SPOTs will continue to load the strings to which they are attached.
