In one embodiment there is provided a power management system for managing the power from solar panels and rechargeable batteries to power a system that includes DC loads and AC loads. The power management system includes a DC-DC converter in communication with the solar panels, a first switch positioned to control power from the DC-DC converter, to and from the rechargeable batteries, and to the DC loads and AC loads, and when in response to a power requirement from the system being equal to or less than a solar panel power provided by the solar panels, the first switch automatically set, by the power management system, to supply the system with only the solar panel power, and wherein any excess solar panel power not consumed by the system is at the same time automatically directed to recharge the rechargeable battery.
