If repeated: measure grid, adjust parameter, then contact service.

review note: support check: partial - The inverter detects unbalanced three-phase voltage, but 'grid voltage measurement' appears only as a manual troubleshooting step, not the detection method.

c5 drafted · lead Utility company consultation

c6 drafted · lead Inverter parameter adjustment

Only when phase difference is within utility-permitted range.
