Abstract: The present disclosure is directed to a padmount transformer. The padmount transformer includes an electrical distribution transformer housed in a cabinet that can be mounted on a ground level platform or pad. High/medium voltage connectors of the electrical distribution transformer can connect to high/medium voltage terminals of a power supply network. Low voltage connectors of the electrical distribution transformer are configured to connect to low voltage terminals of one or more loads coupled to respective renewable energy sources. The high/medium voltage connectors and the low voltage connectors are housed in the cabinet. An energy storage apparatus is housed in the cabinet and is connected with the low voltage connectors for supplying power to the loads. Power can be supplied to the energy storage apparatus by the renewable energy sources. An inverter is operable for commanding the power supply direction at the energy storage apparatus and a control unit is configured to control the inverter.
