On my Xantrex charger, I have had to do a hard reset a couple of times to get rid of internal fault codes. That is disconnecting the charger from both 1220v input and also the 12V DC output to battery banks. For disconnecting from 12V DC, I have found that just unhooking the ground is sufficient. Need to give it a couple of minutes unhooked for codes to evaporate from memory. Then reconnect and restart the unit. You may have to reprogram the parameters. Mine is just a charger, not charger/inverter. So not sure if this will work for you. I had 3 brand new Xantrex chargers that were faulty. All 3 had same lot number. Finally got them to give me one from a different lot and all has been good other than having to do a couple of hard resets in that last 2-3 years.
