One of my sites is a 3 phase system with 3 multiplus 5kVA and Fronius Symo 12.5. Last week the system stopped accepting the 3 phase generator which was working fine two days before. No physical electrical changes have been made.
Would a 3 phase multiplus system ever reconfigure itself to cause a phase rotation issue? The system is set up to accept a "dirty power" generator which was working fine on tuesday, then yesterday the system rejected the generator completely. No-one changed any wiring. Today I rotated 2 phases then the system accepted the generator again.
Is there any possibility at all that the Victron system can change its own phase rotation configuration? A notable event is that yesterday the L1 phase from grid dropped off, L2 and L3 remained on.
Any one with experience on this?
