My Orion TR 30-30 non-isolated did not load the batteries during my last drive. After investigating the issue I found that apparently the firmware was stuck/ crashed. The input voltage was displayed as being 12,4V while it actually was 12,7V.
Resetting the setting to factory defaults did not solve the problem. I had to disconnect input and output for a few minutes until Bluetooth connection was no longer possible. Then it worked again and is also charging again
Did anyone have this issue as well? Is there a way to fix it except physically disconnecting the ports?
