100/30 MPPT intermittent fault

f157a151-4fc8-4bf6-b8f5-c1d89d3b43cb.pngG’day . Ive got a 100/30 MPPT with 3x175w mono victron panels in series. Been working flawlessly on the caravan for 5 months . Yesterday noticed the charger was off and solar voltage was around 13v . I disconnected the MPPT from solar and battery for approx 15 minutes and when reconnected it appeared to be working . Today it has done the same . See attached

You appear to have a high resistance connection in your PV array. Check all joins, connectors, fuse, breakers etc, in the array wiring.

Could also be a bad panel, check by taking 1 panel out of service at a time.
