I got some used SolarWorld (SW 235 Poly) panels last weekend. Finally got them out to test. Tested them with a DMM. The current rated/measured is 8.35/7.57, and the VOC is 37.0/35.5. The other panel is very close to these numbers as well.
I was expecting at least some diminished performance, say down around 80%, but they are not eve activating my Victron 100/20 controller. I can switch over to one of the new Harbor Freight 100W panels and I'm getting 89W from them, charging to the battery.
The polarity is fine. Is there a setting I'm missing? The controller is connected to a "half depleted" Dakota 12V 54ah LiFePO4 battery.
Edit: Bad Connector. Fixed it. Power is only about 150 right now, but at least it's charging the system. Clouds rolling over occasionally so there's that. The Houston area is a little iffy sometimes.
