My new multuplus C 12/1600/70 is occasionally shutting off during charge, going to a red LED. After a short while it resumes charging.
I noticed this so I connected the usb device and loaded Victron Connect. After a short while it happened again and I got this-
Meanwhile the battery shows this, with no over voltage, undervoltage errors or any BMS-induced battery shut off-
The AC output cable of the inverter is mostly disconnected while I'm testing or with a small load- behaviour either way is the same. There is nothing else in the DC circuit:- just the multiplus with its factory cables, (-) straight to battery, (+) into a 200A breaker, then 50mm2 cable for 20cm to battery.
Any idea what these errors / shut downs could mean?
