Abstract

A power management system for selectively providing power to one or more electrical loads using a standby generator includes a meter mounted transfer switch, a power management module, and a controller. The meter mounted transfer switch is configured to receive electrical power from a utility source. The power management module is configured to receive electrical power from each of the standby generator and the utility source. The controller is in communication with the standby generator and the power management module, and monitors a load on the standby generator and communicates to the power management module to selectively disconnect at least one of the one or more electrical loads based on the monitored load.

First claim

What is claimed is:

1. A power management system for selectively providing power to one or more electrical loads using a battery, the power management system comprising:
a meter mounted transfer switch, the meter mounted transfer switch configured to receive electrical power from a utility source, wherein the meter mounted transfer switch further comprises a plurality of contacts extending from a housing of the meter mounted transfer switch to be received by a meter socket;
a power management module configured to receive electrical power from each of the battery and the utility source; and
a controller in communication with the battery and the power management module, wherein the controller monitors a load on the battery and communicates to the power management module to selectively disconnect at least one of the one or more electrical loads based on the monitored load.

2. The power management system of claim 1 , wherein the power management module is installed at a lead of an appliance, wherein the appliance is one of the one or more electrical loads.

3. The power management system of claim 1 , wherein the controller is positioned within the housing.

4. The power management system of claim 3 , wherein the controller is configured to monitor the utility source and couple the battery to the power management module in response to detecting an interruption in power supply from the utility source.

5. The power management system of claim 4 , wherein the controller is configured to disconnect the power management module from the utility source and connect the power management module to the battery by adjusting a position of a transfer switch within the meter mounted transfer switch.

6. The power management system of claim 1 , wherein the power management module receives instructions from the controller via a wireless gateway.

7. The power management system of claim 6 , wherein the wireless gateway uses a combination of WiFi and Zigbee protocols.

8. The power management system of claim 1 , wherein the power management module comprises a module housing, one or more contacts extending from the module housing to be received within a socket, and one or more contact jaws structured to receive one of the one or more electrical loads.

9. The power management system of claim 1 , wherein the meter mounted transfer switch further comprises two fuses to provide overcurrent protection to circuitry in the meter mounted transfer switch.

10. A battery backup system that is configured to be coupled to a power management module to provide electrical power to one or more electrical loads, the battery backup system comprising:
a housing; and
a controller received within the housing, the controller being configured to selectively disconnect at least one of the one or more electrical loads by communicating to a transfer switch of the power management module to move between first and second positions for connecting the battery backup system to the one or more electrical loads;
wherein the controller monitors a load on a battery and communicates to the power management module to selectively disconnect at least one of the one or more electrical loads based on the monitored load.

11. The battery backup system of claim 10 , wherein the controller communicates instructions to disconnect at least one of the one or more electrical loads to the power management module via a wireless gateway.

12. The battery backup system of claim 11 , wherein the wireless gateway uses a combination of WiFi and Zigbee protocols.

13. The battery backup system of claim 11 , wherein the wireless gateway is hard-wired to the controller.

14. The battery backup system of claim 10 , wherein the controller is further configured to connect the battery to at least one of the one or more electrical loads after detecting a loss of power from a utility power supply.

15. The battery backup system of claim 10 , wherein the controller is located within a control compartment, and further comprising a removable cover for the control compartment to provide access to the controller.

16. A power management system for selectively connecting a primary power supply or a secondary power supply to a plurality of electrical loads, comprising:
a meter mounted transfer switch comprising:
a first housing; and
at least one transfer switch contained within the first housing and movable between a first position and a second position, wherein the transfer switch changes from the first position to the second position to selectively disconnect at least one of the plurality of electrical loads from the primary or secondary power supply; and

a controller within a second housing of the secondary power supply configured to monitor a load on the secondary power supply, and wherein the controller communicates to the at least one transfer switch to change positions to selectively disconnect one of the plurality of electrical loads from the secondary power supply based upon the monitored load.

17. The power management system of claim 16 , wherein the meter mounted transfer switch further comprises two fuses to provide overcurrent protection to circuitry in the meter mounted transfer switch.

18. The power management system of claim 16 , wherein the controller instructs the at least one transfer switch to change positions in response to detecting no power on load sides of any latching relays of the meter mounted transfer switch.

19. The power management system of claim 16 , wherein the secondary power supply is a battery.
