4.5 Zero-injection Smart Meter (Optional)
Step 1
Smart meter is an intelligent control equipment which is used for on-grid
inverters. Its main function is to measure the forward and reverse power on
the grid-connected side, and transmit data to the inverter through RS485
communication to ensure that the power of the inverter is less than or equal
to the user's home load, and no current flows into the grid.
Note:
please follow below pin order
RS485B (Pin 1/2) to three-phase meter (Pin 25)
RS485A (Pin 3/4) to three-phase meter (Pin 24)
