MPPT intermittent charging

e417591f-0bc0-4a7e-8d4d-55b95dcdae1c.pnge6b45965-98df-4054-8e3e-b77c4eb52804.pngI have a bank of four Victron solar panels connected to a 150/70 MPPT.

Sometimes it charges fine then a few minutes later it stops but still shows voltage

By switching off the main breaker between panels and MPPT and back on again the panels start charging, 30A+ but then stop again after a while. Is there a setting I’m missing somewhere?

Many thanks

Alex
