The Blue Sky Solar Boost features reverse-polarity protection, MPP tracking and selectable-charge voltage for flooded and gel lead-acid batteries. An equalize function periodically conditions 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 and charge mode, either in the controller, as a remote panel installed up to 300 feet away, or both. Optional temperature compensation of charge voltage is also available to further improve charge controller and battery performance. Solar Boost controllers available with or without digital display and optional remote display. 3-year limited warranty.

     SB3024i is designed to charge 12- and 24-volt battery systems from a 24-volt array (maximum open circuit voltage is 57). Maximum charge current is 30 amps output at 12 or 24 VDC. The new IPN network interface coordinates multiple controllers and shares temperature sensors and display. This is the front cover with digital display for model SB3024i.
