Solar Boost 50 does much more than increase charge current. It offers an advanced fully automatic three stage charge control system to ensure the battery is properly and fully charged, resulting in enhanced battery performance with less battery maintenance. Reliable high efficiency power conversion is achieved using the latest generation power MOSFET transistors, with output power delivered via a series pass Pulse Width Modulation (PWM) control scheme. An electronic current limit feature prevents output current from exceeding 50 amps. Output current limit eliminates worry about overload or nuisance fuse blow when PV output is unexpectedly high. An equalize function is also included to periodically condition liquid electrolyte lead-acid batteries.

An optional user friendly digital display is available to monitor PV charge performance. The display shows battery voltage, solar current, charge current, charge mode and state of charge. It can be provided in the controller, as a remote panel installed up to 300' away, or both. Optional temperature compensation of charge voltage is also available to further improve charge control and battery performance. Selectable compensation curves support lead-acid and NiCd battery chemistries.
