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.

     The 6024HDL is designed for charging 12- or 24-volt batteries from 36-, 48- or 60-volt PV arrays (maximum open circuit voltage is 140). This allows for a much smaller wire size between the array and battery in large systems. Maximum charge current is 60 amps at 12 or 24 volts. This controller comes with digital display.
