DRM port
DRM is used to connect the DRM controlling device.
When the COM. port set to DRM port, the PIN7 and PIN8 of inverter’s RJ45 plug cannot connect
wires. The PIN7 and PIN8 of external DRM adapter’s RJ45 plug must be short connected together.
RS485 communication port
RS485 communication port is used to communicate with smart meter to achieve anti-countercurrent.
The connection between smart meter and inverter and grid is as shown in Figure3-42

When using the anti-countercurrent function, the following setting must be done:
− Set the anti-countercurrent enable in "System Setting-General Setting-I/O set" to open;
− Set the anti-countercurrent power in "System Setting-General Setting-Engineer set" according
to the actual use (the setting value of anti-countercurrent power is percentage, it is corrected
