Ouch. Then it sounds like you need to get a Victon-knowledgeable specialist involved. In the Victron configuration utility (for which you need a special dongle and software), there is a tick box to be ticked if you want the unit to provide UPS (uninterruptable power supply) funtionality. The scenario you describe makes me wonder if this is ticked "on" (it should be on). But again, if you don't have the software or the dongle, you need to call a Victron specialist to come have a look.
