Victron Energy RV power converter fault codes
RV converters/chargers turn shore or generator AC into 12V DC and charge the battery. Most show charge-mode LED indicators rather than numeric codes; "faults" are usually no-output conditions.
How to read the code
Read the charge LED colour/blink pattern and check the DC fuses. No 12V output most often means a blown fuse or a tripped thermal/reverse-polarity protection.
Models covered: every code below applies to the Victron Energy Orion XS 12/12-50A DC-DC charger.
