Multiplus 24/2000 , latest firmware. All connections triple checked.
I’m off grid so in winter I occasionally have to supplement PV with a generator. I haven’t had to do this since I swapped to lithium batteries earlier this year, so my multiplus was happy with the generator input last year, but not now.
Voltage at the multiplus AC IN terminal shows 226v with a multimeter. However Victron Connect says it is 89v.
All connections checked and confirmed with my dealer.
All settings at defaults except lithium toggle and slight tweaks to charge voltages
The inverter works fine.
My dealer has never seen this before. I’m out of warranty so I’m trying to understand how this could happen.
I may have to disconnect the multiplus and battery and lug them to where there is mains electricity to see if that works. If there’s any troubleshooting I could do before straining my back, I’m very open to ideas!
