F46AC output mode setting is different.Fault
Description

Fault: AC output mode setting is different.

Cause

Inconsistent AC output mode (program 28) settings across paralleled inverters.

Recommended fix

1. Switch off the inverter and check LCD setting program 28. 2. For parallel system in single phase, make sure no 3P1, 3P2 or 3P3 is set on program 28. For supporting three-phase system, make sure no "PAL" is set on program 28. 3. if the problem remains, please contact your installer.
