We have different consumers connected to AC1 and AC2 output on our multiplus 12/3000/120 installed in a van. We do have a BMV712 and a Digital Multi Contol connected on the VE.Bus limiting the input current and controlling the battery.
When input is connected to grid, AC1 (with power assist) and AC2 are working fine with input current limit set on multi control.
When we use a generator (Honda 22E Inverter) as input, the multiplus disconencts after some time completely from input even with very low load on AC1/AC2 (far beond power delivery of the generator). AC2 gets offline and does only recover for some short period afte 2 minutes. AC2 alternates on and off.
The multiplus is connected to ground on van chasiss as well as the PEN of input is connected to van chassis. During operation van chassis is grounded by grounding rod.
What is wrong with the configuration? Grounding issue? Specific generator issue?
