Hello,
I recently purchased a Multiplus 2000. After using it for about 2 weeks it began to go to alarm randomly while it was in inverter mode. It’s wired in parallel with another smaller inverter and to 4x 100amh battle born batteries and is used to run 3 Danby fridges. At first only 1 or 2 fridges would trip the alarm but after about a week even a very small load like a cellphone charger would trip the alarm. The inverter does seem to charge the batteries while on shore power as well as power the fridges while on shore power. It will go to alarm a few minutes after switching to inverter only.
Thanks for your help.
