First Claim
1. A power management system, comprising:
- a solar panel interface to one or more solar panels, the solar panel interface comprising wiring for;
(a) receiving solar panel sensing signal representative of a voltage in the solar panels and (b) conducting one or more electrical currents received from the solar panels;
an energy storage interface to one or more energy storage devices, the energy storage interface comprising wiring for;
(a) receiving an energy storage sensing signal representative of a voltage in the energy storage devices and (b) conducting one or more electrical currents received from or provided to the energy storage devices;
a charging circuit which routes the electrical currents from the solar panels to the wiring for conducting electrical currents received from or provided to the energy storage devices;
a load interface to a plurality of load devices, each load device being connected to either a primary load circuit or a secondary load circuit, the load interface comprising wiring for;
(a) receiving a load sensing signal representative of a voltage in the load devices and (b) conducting electrical currents to the primary load circuit and to the secondary load circuit;
a controller for operating the solar panel interface, the energy storage interface, the charging circuit and the load interface,a programmable controller which executes a method for waking up the one or more energy storage devices, wherein the method performs a wake-up operation on the one or more energy storage devices when an elapsed time between the wake-up operation and an immediately preceding wake-up operation exceeds a predetermined time period; and
a secondary load control circuit which routes the electrical currents from the energy storage devices to the wiring for conducting electrical signals in the load interface, the secondary load control circuit being capable of activating or deactivating the secondary load circuit independently of the primary load circuit.

Abstract
A portable solar power management system includes (i) a solar panel interface to one or more solar panels, (ii) an energy storage interface to one or more energy storage devices, (iii) a charging circuit which routes the electrical currents from the solar panels to the energy storage devices; (iv) a load interface to one or more load devices, the load devices being powered independently on primary and secondary load circuits; and (v) a controller for controlling the operations of solar panel interface, the energy storage interface, the charging circuit, and the load interface. In addition, a secondary load control circuit and a programmable controller may be provided which route the electrical currents from the energy storage devices to the load interface, wherein the programmable controller, based on the sensing signals, also activates and deactivates the secondary load circuit.
