Blue Sky Energy Solar Boost

Blue Sky solar boost 50L charge controllerThe Blue Sky Solar Boost 50L MPPT Charge Controller uses Maximum Power Point Tracking technology to improve charge current up to 30% or more.

The Solar Boost 50L charge controller uses patented Maximum Power Point Tracking (MPPT) technology. MPPT allows the Solar Boost 50L to increase charge current up to 30% or more compared to conventional solar charge controllers. Don’t waste money by throwing PV power away! Get the power you paid for with a Solar Boost 50L charge controller.

The Solar Boost 50L controller also provides 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. 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. Optional temperature compensation of charge voltage is also available to further improve charge control and battery performance.
