May 17, 20224 yr Hi all Has anyone had this issue before? I have 2 strings of panels, PV1 & PV2, 3 days ago PV1 stopped producing power. I.e 1-7W yet the voltage stays up around 400-450v PV2 is working as normal. I have check all setting on inverter and restarted etc but PV1 refuses to produce W's despite the voltage being fine. They are brand new JA solar panels. All connections checked etc. Any ideas?
May 17, 20224 yr You didn't say what model inverter you have. Is 450 V perhaps right on the absolute maximum limit of allowable PV voltage? If it actually exceeded your inverter's safe limit, that might have damaged the Solar Charge Controller.
May 18, 20224 yr Author Hi Its an Infinisolar 10.5Kva - the string is 11x 455W panels at abt 540V max. The min V the inverter requires is 300V so the voltage is well in range. It has been working just fineuntil a few days ago when they just stopped producing Wattage...
