[QUOTE="binky, post: 519079, member: 490"] I would try one other thing first, when it gets upto the 80% mark, try putting on the washing machine and tumble dryer and see how it behaves then. I'm interested if having a load on the system stops string 2 from shutting down whilst still charging the battery? I'm thinking if this is the case, then it's a power control function of the inverter. The trouble with PV is checking continuity of a cct, which would show a dodgy joint, isn't very feasible as we don't have any info on the resistance of the panels - it's bugged me for years as this is a basic check for electrical ccts. The only thing I can suggest is powering down that string and a physical inspection of each connection ie disconnect them all and check for any signs of thermal damage on the connector pins, also look to see if the pins are fully located in place and not slightly short of the joining ends of the connectors. Also check the cable nuts are fully done up. Obviously be very careful when doing this as all pins are live so no poking fingers in the ends. [/QUOTE]
