Abstract
An intermitently operable non-fuel-consuming power generator, such as a photovoltaic array or a wind generator, is connected through a control circuit to a battery for charging the same and supplying current to a time-wise substantially constant electrical load. An electrical generator, connected to an intermitently operable prime mover, charges the battery and supplies current to the electrical load when the prime mover is operated. A sensor circuit senses at least one electrical parameter, such as a failure of the power generator to produce current, for controlling the operation of the primer mover (i.e., starting of the prime mover). The sensor circuit also senses a second electrical parameter, such as the charge level of the battery. The prime mover is made operational only if the battery capacity is less than a predetermined threshold level when the power generator fails to produce current.
