Off grid RV with 50 amp service. Multiplus II 12/3000 2x120v. Won’t charge batteries with generator running, 125 volts are detected on line 1 and line 2, but 0 amps (And only 0 amps, it‘s not like it starts to charge and then quits. Multiplus lights are “Mains On” and “Float” (some times Absorption instead of float). No other warnings/errors. Generator is a Cummins/Onan P4500i inverter generator.
I‘ve gone through all of the settings changes as outlined in the Victron generator faq to no avail.
The generator is attached to the Victron through a 30 amp to 50 amp dogbone adaptor.
I have a theory that the issue may be related to the fact the generator has a floating neutral. Does this make sense?
I’m thing of bonding the neutral and ground at the generator and seeing if that helps. Thought it best to seek others expertise so that I don’t let the magic smoke out of anything.
Anything else to try not already covered in the FAQ?
I have access to a second portable generator, also with floating neutral, but different brand. I’ll give that a try for sh*ts and giggles, but am expecting the same issue.
