Hello,
I have a few of these units in parallel (was told it was okay from communication with victron staff). Anyways, today I'm getting an fault #27 on one of the chargers. When I did a search, I see that some of devices firmware were updated due to a false-positive fault #27. I don't see any short. I have a 2ft 8 awg cable from the charger to the busbar. Any ideas?
