We have a Multiplus Compact 12/2000 with a Digital Multicontrol.
When we start the generator the AC output of the inverter briefly goes to "bulk charge" and then quick back to "inverter" mode.
When setting the switch to “charge only” it briefly switches for a few seconds to “bulk charge” where after it goes right back to “inverter” as well. It keeps repeating this.
I checked the inverter ACinput voltage / frequency: 125VAC and 60.2 HZ, well within spec.
The dipswicthes are set as follow:
All: off except for 4
Any idea what this could be?
