Abstract

An energy supply system for supplying electrical energy to a building, comprising a meter socket adapter, a principal switching device, an electrical backup device, and an appliance disconnector. The meter socket adapter is placed between a service panel socket and a standard utility meter, allowing the principal switching device to disconnect the building from the power grid. The appliance disconnector is then activated to implement an emergency power prioritization.

a principal switching device connected to said grid side connections and said load side connections, wherein said principal switching device is constructed to, when activated, electrically disconnect one, two or more of said load side connections from the corresponding grid side connections;

an electrical backup device constructed to supply electrical power to said electrical appliances in said building when said principal switching device is activated;

an appliance disconnector electrically placed between said backup device and an appliance of the building and constructed to, when activated, stop electrical power flow from said backup device to said appliance; and

a control device constructed to control said principal switching device and said appliance disconnector such that when said principal switching device is activated, electrical power flow from said backup device to said appliance is stopped, while at least a further appliance receives electrical power from said electrical backup device.

2. The energy supply system according to claim 1, wherein said meter socket adapter comprises on its meter side socket jaws arranged to receive jaw blades of said utility power meter and on its panel side jaws arranged to fit into socket jaws of said service panel socket.

3. The energy supply system according to claim 1, wherein said meter socket adapter comprises an enclosure having a meter side flange on its meter side and a panel side flange on its panel side for retainers to secure said body to said utility power meter and said service panel.

4. The energy supply system according to claim 3, wherein said principal switching device is placed inside said enclosure of the meter socket adapter.

5. The energy supply system according to claim 1, wherein said appliance disconnector is placed inside said service panel or inside a distribution board of said building.

6. The energy supply system according to claim 1, wherein said appliance disconnector is placed at or inside said appliance.

7. The energy supply system according to claim 1, wherein said appliance disconnector is controlled remotely by said control device.

8. The energy supply system according to claim 1, wherein said control device is constructed to activate said appliance disconnector in dependence of a state of charge or a power level of said backup device.

9. The energy supply system according to claim 1, further comprising a grid power monitoring device for monitoring the voltage level at said grid side connections.

10. The energy supply system according to claim 9, whereby said control device is constructed to control said principal switching device in dependence of the result of the monitoring of said voltage level.

11. The energy supply system according to claim 10, wherein said control device is constructed to, depending on the voltage level of said electrical grid or depending on a power level of the backup device, either activate the principal switching device and allow only the backup device to supply the grid side connections with electrical power or to maintain a connection of said backup device with said electrical grid.

12. A method for supplying electrical energy to a building, comprising the following steps:

activating a principal switching device, which is connected to grid side connections, for receiving power from the electrical grid, and load side connections, for supplying the received power to electrical appliances in said building, of an energy supply system for supplying electrical energy to said building, thereby electrically disconnecting one, two or more of said load side connections from the corresponding grid side connections;

providing electrical power by an electrical backup device for said electrical appliances in said building;

activating an appliance disconnector, which is electrically placed between said backup device and an appliance of said building, thereby stopping electrical power flow from said backup device to said appliance; and

supplying at least a further appliance with electrical power from said electrical backup device.

13. The method according to claim 12, wherein activating said principal switching device electrically disconnects one, two or more of said load side connections, which are located inside a meter socket adapter, from the corresponding grid side connections, which are located inside said meter socket adapter, wherein said meter socket adapter is engaged on a meter side to a standard utility power meter and on a panel side to a service panel socket, which is constructed to engage with said utility power meter.
