Principle of Anti-Reverse Current of Photovoltaic Inverter
For household low-power grid-connected inverters, the output current is small, generally less than 80A current models (within 50KW), you can directly use a DC anti-reverse current meter,
4 FAQs about What is an anti-reverse flow grid-connected inverter
What is a photovoltaic system with anti-backflow?
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.
Why should photovoltaic power generation system be equipped with anti-reverse flow equipment?
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.
How does an anti-reverse current meter work?
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.
What is the difference between forward power and reverse power?
In the grid-connected two-way meter, the forward power is the power provided by the grid to the load, and the reverse power is the power delivered by the photovoltaic to the grid. 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.
