If there are many such power generating sources to transmit electricity to the power grid, the power quality of the power grid will be seriously degraded. Therefore, this type of photovoltaic power generation system must be equipped with anti-reverse flow equipment to prevent the occurrence of reverse power.
When reverse current is detected, the meter communicates the backflow data to the inverter via RS485 communication. The inverter responds within seconds, reducing its output power to ensure the current flow into the grid is nearly zero. Anti-Backflow Solutions Different configurations are available to meet various scenarios:
The photovoltaic system with anti-backflow is that the electricity generated by the photovoltaic is only used by the local load and cannot be sent to the grid. When the PV inverter converts the DC point generated by the PV modules into AC power, there will be DC components and harmonics, three-phase current imbalance, and output power uncertainty.
Anti-reverse current working principle: Install an anti-reverse current meter or current sensor at the grid connection point. When it detects that there is current flowing to the grid, a signal is sent to the inverter through 485 communication, and the inverter reduces the output power until the reverse output current is zero.
Our standardized photovoltaic container and energy storage products are engineered for reliability, safety, and easy deployment. All systems include comprehensive monitoring and control systems with remote management capabilities.
The inverter AC output terminal wiring is directly introduced into the meter, and then connected to the grid connection point after coming out of the meter to achieve anti-reverse flow.
