The present disclosure relates to a scalable electric provisioning system comprising a housing, a high voltage direct current (DC) backplane, a communication bus, at least one provisioning module and a control unit. The housing defines a plurality of slots. The high voltage direct current (DC) backplane is located within the housing and is electrically accessible through each one of the plurality of slots. The communication bus is accessible to each one of the plurality of slots. The at least one provisioning module is inserted into one of the slots. The at least one provisioning module comprises two sub-units selected from any of the following: a DC/DC converter, a DC/DC bidirectional converter, an electric inverter, and a bidirectional electric inverter. The control unit controls operation of the at least one provisioning unit.
