Anyone heard of this problem?
I’ve got a stable 24v supply in the cab of a unimog. This is from a pair of 12v automotive batteries which enough charge to turn over the engine. And to a known good ground point on the chassis.
When I connect a Victron 24v-12v isolated dc converter it drags the voltage down to 11v. It then creeps back up to 15v over about 30 seconds, at which point the Victron undervoltage deactivates, I get a brief power flash on the Victron, and it drops the voltage to 11v again and undervoltage triggerw. It then repeats.
Disconnecting the Victron returns the voltage to a steady 24v.
This is with no load on the dc-dc convertor and the same occurs weither the remote is shorted or open.
