So I have a multiplus compact 24v 2000 that a friend pulled out of service and asked me to look at because it started to act strange. Intermittently it will invert but will shortly stop doing anything. If mains power is applied to the input the unit will not close it’s contactors and bridge the input to the output.
The alarm light will flash every now and then but nothing substantial to note of it, like a blink code or anything.
I have a MK3 USB cable that I have hooked up to the inverter to see what errors there are using the VEConfig software but I don’t see anything amiss. Is there a way in the VEConfig software to see the errors of the device as they occur or is that only possible with the CCGX display?
