Colin Walker got a reaction from ahmed677 in Grid Phase Wrong AlarmI have the latest firmware and installed two three phase 12kw in parallel.
checked all the wiring on the DB , did continuity tests and swapped incoming white and blue around ( anti-clockwise on main council board).
The Sunsynk technician said switch off all the loads ( drop main breaker in the house) then change grid setting to 0/120/240 ( clockwise - checked with meter). When Inverter alarms W03 turn off and then start again. This should sort it out.
Unfortunately I have not been successful.
What he told me though was if you don’t have 3 phase devices then this setting doesn’t really matter ( as nothing will run backwards) as it does not effect the inverter.
what breaks the inverter is trying to change this when running a full load .
