Claim 17:
18. A method for controlling an electrical load in a load control system, the load control system having a plurality of load control devices for controlling a plurality of electrical loads, wherein the plurality of load control devices are configured to be coupled in parallel with each other across a DC power bus to receive a DC bus voltage from a DC power supply, the method comprising:”
receiving the DC bus voltage from the DC power bus;
controlling when an internal energy storage element charges from the DC bus voltage;
controlling a load control circuit for controlling power delivered to an electrical load using current conducted from the internal energy storage element;
sending an indication of a storage level of the internal energy storage element;
receiving an indication of a storage level of an energy storage element of another load control device; and
determining to charge the internal energy storage element from the DC bus voltage based on a comparison between the storage level of the internal energy storage element and the received storage level of the energy storage element of the other load control device.
