A high voltage maximum power point tracking bidirectional charge controller for photovoltaic (PV) systems having a high voltage PV array, a battery bank and a high voltage DC load comprises a DC to DC converter electrically connectable to the high voltage PV array, the battery bank, and the high voltage DC load. The converter receives DC input from the PV array and operates in a first direction to step-down the voltage of the DC input to obtain a stepped-down DC output of appropriate voltage to charge the battery bank. The converter receives DC input from the battery bank and operates in a second direction to step-up the voltage of the DC input received from the battery bank to obtain a stepped-up DC output of appropriate voltage for the high voltage DC load.
