    Blue Sky Energy Solar Boost Charge Controllers

    The Blue Sky Solar Boost charge controllers feature Maximum Power Point Tracking (MPPT), reverse-polarity protection, selectable charge voltage set points, and an equalize function. 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' away, or both. Optional temperature sensor provides for compensation of charge voltage to further improve charge controller and battery performance. Solar Boost controllers are available with or without the digital display and optional remote display. 5-year limited warranty.

    Solar Boost 3024iL

    The SB3024iL is designed to charge 12 and 24 DC battery systems from a 24 VDC array (maximum open-circuit voltage is 57 VDC). Maximum charge current is 40 A output at 12 VDC and 30 A at 24 VDC. It has an auxiliary output that can serve as a 20 A load controller or as a 2 A battery charger. The SB3024DiL version adds a front-mounted digital display.

    The DUO-Option software upgrade converts the auxiliary output into a 20 A diversion type PWM charge controller. The DUO-Option upgrade allows a 3024 to provide charge control for hydroelectric, wind or similar DC generators requiring diversion type charge control while at the same time providing MPPT type PV charge control. The MPPT PV power controller and the diversion power controller operate as a single coordinated charge control system fed by multiple power sources. Operation is similar to the coordinated operation of multiple 3024’s on Blue Sky Energy’s IPN Network. This coordinated approach provides better battery charge control for hybrid systems compared to using a separate diversion charge controller. For dump load applications exceeding 20 A, the Current Booster Module CBM4070 will support dump loads up to 40 A. The CBM4070 is driven by the auxiliary output of a DUO-Option equipped 3024.

  • 40 amp 12V or 30 amp 24V rating supports a wide range of aplications
  • Auxiliary output serves as 20 amp load controller or 2 amp battery charger'Load controller provides fully adjustable dusk to dawn lighting control
  • IPN network interface coordinates multiple controllers & ahares optional battery temperature sensor & display.
  • Optional IPN-ProRemote display provides complete charge control & battery system monitoring eliminating the need for a seprate battery monitor device.
  • 3-stage charge control with filtered PWM output & auto/manual equalization improves battery perfomance & life.
  • MPPOT power converter can charge 12 volt batteries from 24 volt PV modules
  • Durable Power converter coat finish & conformal caoted electronics resist corrosion
  • Full 5 Year limited warranty.
  • Battery temprature sensor input.

    Dual 30/40A rating delivers up to 30 A in 24V systems, or up to 40 A in 12V systems. An automatic or manual equalize function is provided to periodically condition flooded lead-acid batteries. A user configurable auxiliary output & IPN interface included
