I’m on a liveaboard in the reading region with Whisper Genverter W-GV4 that is supposed to be feeding into a Victron multiplus 12 3000 120. But it isn’t. The multiplus is rejecting the feed. It accepts the feed from the main engine alternator. I stopped using the generator in the spring and now need it for the winter. The multiplus used to accept the GV4. Also, and I don’t know it this is related, the GV4 is supposed to idle at 2500 RPM to synchronise with the multiplus, but half the time when it starts it steadies itself at 2230 RPM which is too slow to give a stable output. Strange. Any ideas? Anyone?
