| This is the screen on the charge controller, which is the unit that regulates the battery charging from the power of the solar array. It shows input from the solar array at 93.8V and 25.9A. This MPPT (maximum power point tracking) charge controller translates this input to 58V and 40.3A for charging the battery. The battery bank has a nominal voltage of 48V. |
