A bidirectional DC/AC conversion unit (33) converts DC power stored in a storage battery (15) into AC power, and outputs the AC power to each of the loads.

The resonant circuit (10) induces an alternating power, which is in accordance with the ON-times of the switching elements, in the primary coil through the switchings of the switching elements.

The resonant circuit (10) induces an alternating power, which is in accordance with the resistance value of the resonant circuit (10), in the primary coil through the switchings of the switching elements.

Solar energy panels require additional equipment (solar inverters) to convert direct electricity (DC) to alternating electricity (AC) in order to be used on the power network.

2 × (MWh(electricity)) / [2 × MWh(electricity) + MWh(heat)]

2 × (MWh(electricity))/[2 × MWh(electricity) + MWh(heat)]
