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 happens if solar power input is reversed?
If the solar power input is reversed, the power will form a short circuit through the anti-parallel diode. According to the characteristics of the solar module, the voltage of the solar power supply When pulled down, the voltage value is only the sum of the forward voltage drop of the two diodes, which will not damage the electrolytic capacitor.
