Abstract: A behind-the-meter system for controlled distribution of solar power to units in a multi-unit building connected to an electric power grid. The system includes a grid-tied inverter connectable between a solar power generator and the electric power grid sensors for measuring instantaneously power demand and solar power consumption of the units and solar power generation and switches for connecting and disconnecting the units from the solar power generator. A controller, connected to the sensors and the switches determines relative values of power demand and solar power consumption of the units based on the instantaneous measurements of the power demand and the solar power consumption, and controls the switches to distribute solar power from the solar power generator.

Abstract: An AC power sharing system for connecting an AC power source to at least two loads, the system comprising: power distribution board, the power distribution board having at least one input for receiving AC power from the AC power source; and, the power distribution board further comprising at least two relays, each relay for connecting the distribution board to a load, each switch having an OPEN/CLOSED configuration, wherein in the CLOSED configuration the relay is configured to connect the AC power source to a load to provide power from the AC power source to the load; wherein the relays comprise two IGBTs or MOSFETs arranged with their load side terminals connected in anti-series.

Abstract: A behind-the-meter system for controlled distribution of solar power to units in a multi-unit building connected to an electric power grid, the system comprising: a grid-tied inverter connectable between a solar power generator and the electric power grid; sensors configured to measure instantaneously: power demand and solar power consumption of the units; and solar power generation; switches configured to selectively connect and disconnect the units from the solar power generator; and at least one controller, connected to the sensors and the switches, configured to: determine relative values of power demand and solar power consumption of the units based on the instantaneous measurements of the power demand and the solar power consumption of the units; and selectively and individually control the switches to distribute solar power from the solar power generator between the units based on the relative values of the power demand and the solar power consumption of the units.
