Will check that, as coupled with being able to pair with the inverter it gives a bit more confidence but would ideally like to see some power coming through them.

The inverter datasheet gives a max input of 500vdc, a nominal input of 350vdc but no minimum. The optimisers output is max 60vdc, so way short of 350 and I guess thats the reason for needing a minimum of 8 on a string. Just trying to see if theres another way to test without buying another 7 panels.

Hi. Has anyone any experience of optimiser testing? Ive picked up 10 unused but "shop soiled" P350s off ebay and want to check they are all good before installing on the roof. Ive got a 4kw solar edge inverter and a single 245w solar panel. I can get individual optimisers to pair with the inverter when the panel is connected and powering the optimiser but I dont see any generation after pairing. The data sheet says each string should have a minimum of 8 optimisers so I assume this is the problem. I dont have access to 8 panels at the moment so am wondering if theres any other way to fully test them??
