Solar Boost 50 is a 12/24 volt photovoltaic (PV) charge controller capable of delivering up to 50 amps of output current. Patent pending maximum power point tracking (MPPT) technology allows Solar Boost 50 to extract more power from the PV array, resulting in a charge current increase of up to 30% or more. Controllers without this technology simply can't deliver the current provided by Solar Boost 50. Don't waste money by throwing PV power away! Get the power you paid for with Solar Boost 50.

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 power production 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 panel current, output charge current, charge mode and state of charge. It can be provided in the controller as pictured above, 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 temperature conpensation curves support both lead-acid and NiCd battery chemistries.
