I have 10 used panels from San Tan Solar with VOC 36.7. Right now I have them split into 2s2p(73.4v) into one inverter and 2s3p(73.4v) into the other. The max pv voltage logged so far has been 65v. The Growatts have a max VDC of 145. My question is, should I raise the voltage by reconfiguring it to 3s2p(110.1v) into one inverter and 4s(150.4v) into the other. It would raise the VOC slightly above the rated VDC on the 4s side but the way the panels are mounted on both sides of a well shed/shop roof and are not pointed at the sun it would have no chance of overvoltage. So far the panels run at 65% max. Would re-wiring the panels raise the efficiency?
