SOLAR BOOST™ 50 & 3048

• The Ultimate Photovoltaic Charge Controllers... Increase Charge Current Up To 30% Or More!

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-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.

*- Nominal PV module voltage must be greater than or equal to nominal battery voltage. PV VOC rating at STC should not exceed maximum controller rating ÷1.25. See Technical Bulletins 100214 & 100210. Typical 12V nominal PV module provides VMP≈17V & VOC≈21V at STC. ** - Approximate maximum PV power handling capability after applying NEC 1.25 current derating. See Technical Bulletins 100214
