Hello, new small off-grid solar setup in progress. Have 4 100 watt panels mounted and wired in parallel, just checked voltage from the leads that will go into the charge controller and am getting a little over 20 volts, like about 20.3.
I have a 30A Wanderer charge controller and just want to make sure i'm not doing something wrong
There's 2 Renogy panels I bought new and 2 Sungoldpower panels I got from a friend moving away, here are the specs:
SUNGOLDPOWER SG-100WM PANELS:
Production tolerance: ±3%
Maximum Power Current (Imp): 5.24A
Maximum Power Voltage (Vmp): 19.1V
Short Circuit Current (Isc): 5.57A
Open Circuit Voltage (Voc): 22.1V
Maximum System Voltage: 800V
RENOGY PANELS:
Maximum Power at STC: 100W
Open-Circuit Voltage (Voc): 24.3V
Short-Circuit Current (Isc): 5.21A
Optimum Operating Voltage (Vmp): 20.4V
Optimum Operating Current (Imp): 4.91A
Maximum System Voltage: 600V DC
Was just wondering if this is normal, I guess I was expecting only 12v. Thanks!
