Technical FAQs 4

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.

How does a reverse current meter work?

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:

How does a 485 inverter work?

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. Thereby, the anti-reverse flow function is realized.

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.
