A MPPT charge controller is rated to operate at a particular DC system voltage, maximum current and maximum voltage. MPPT charge controllers can charge the battery bank with any series and parallel configuration of modules that doesn't exceed the maximum voltage and maximum current or drop below the required charging voltage of the energy storage system. Exceeding the voltage rating of an MPPT due to cold temperatures that increase PV module voltage result in damage. Many charge controllers allow the current rating to be exceeded to a certain point without damage, just lost energy, but this depends on the charge controller. There are several important calculations that must be performed to properly size an MPPT charge controller:
