Overpaneling Solar Charge Controller: A Comprehensive Guide
Voc * 1.25 = Max input voltage. For example, three solar panels have a Voc of 22V each. 22V * 1.25 * 3 panels = 82.5V. If you have a charge controller with a maximum input of 100VDC, you can only use three solar panels in series with a Voc of 22V. You can add more solar panels in parallel to expand your solar array. Input Current
Solar regulators often short the solar panel input when regulating. This does not damage the solar panel, but it does mean that the solar regulator must be sized to handle 125% of the solar panel''s rated short circuit current. Example: A BP Solar 80W solar panel has a rated output current of 4.55 Amps and a rated short circuit current of 4.8 ...
