Purkey’s Fleet Electric has released the new Solar Bolt charge controller, a new charging option that utilizes patent-pending technology designed to work in conjunction with the electrical system on a vehicle or trailer. The module’s technology allows the Solar Bolt to provide power to the liftgate batteries when the vehicle is off or on. Users can choose the wattage used by the charge controller. According to the company, this is the only solar charging system that works while the vehicle is on reducing the electrical load on the alternator, which in turn reduces the mechanical load on the engine, resulting in fuel savings.
