Current feedback into the
inverter is detected
1. Restart the inverter.
2. Check if L/N cables are not connected inversely in all inverters.
3. For parallel systems in single phase, make sure the share
current cables are connected between all inverters.
For three-phase systems, make sure the share current cables
are connected between all units on the same phase, and not
connected to any units on the other phases.
4. If the problem remains, contact your installer
71
The firmware version of
each inverter is not the
same
1. Check the version of each inverter via LCD setting and make
sure the CPU versions are the same. If they differ, update all
inverter firmware to the same version (contact your instraller).
2. If the problem persists after updating, contact your installer
