CAUTION:
Make sure the AC cable is totally isolated from AC power before
connecting the Smart Meter and CT.
A Smart Meter with the CT in product box is compulsory for hybrid system installation.
It can be
used to detect the grid voltages and current directions, provide the operating
condition of the hybrid
inverter via RS485 communications.
NOTE:
1. The Smart Meter with CT is already configured ; please do not change any
settings on the Smart Meter.
2. One Smart Meter can be used with only one hybrid inverter.
NOTE:
Please note that the CT orientation must be correct,
otherwise the system will not work properly
