I have a Multiplus II GX that refuse to charge my battery. It was running fine until it suddenly says "HUB-3" and passthru on the small display. I use it as standby for power failure only, no ESS activated.
I have connected another Victron Easysolar II GX to the battery and everything works fine, so the problem is inside the Multiplus. It shows no error codes, but refuse to charge the battery regardless of what I try). I have updated firmware and checked all settings in VE Config, including using the "reset to default" but this does not help. Is there anything else I can try to reset this unit or do I need to send it in for repairs?
What is HUB-3 mode anyway? I can't find any information online on this (only mode 1, 2 and 4).
