Wrenches - I've got an Eaton HFD3090 90A breaker protecting a Solectria 50TL that's tripped twice in the past 5 days, after having no issues during the first 8 months of system production (including throughout the summer). Monitoring (inverter-direct and RG CTs) shows nothing unusual (all 3 phases <57A) and nothing to indicate a brief edge-of-cloud effect. I'm heading out today to IR the AC connections and expect to see a some color, but being as the site is somewhat remote wanted to check with the group on any other recommendations before leaving. I don't have a logging current meter but might pick up a spare breaker to swap in if all connections check out. Any other suggestions? Anyone ever had nuisance tripping issues with Eaton Series C breakers?
