Patented Maximum Power Point Tracking (MPPT) technology allows Solar Boost 50 and
Solar Boost 3048 to increase charge current up to 30% or more compared to conventional
charge controllers. Don’t waste money by throwing PV power away! Get the power you
paid for with a Solar Boost charge controller.
Solar Boost controllers also provide 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-
