    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 SB3024iL/DUO

    Solar Boost 3024i and 3024iL MPPT charge controllers include a 20 amp load control output. e DUO-Option soware upgrade converts the auxiliary output into a 20 amp Diversion type PWM charge controller. 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. MPPT PV Power Controller and the new 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. is coordinated approach provides superior battery charge control for hybrid systems compared to using a separate diversion charge controller.

    Optimizes Diversion Power Control
    A diversion charge controller regulates battery voltage by diverting a portion of the available charge current to a resistive dump load supplied by the user. With the DUO-Option the user may select either a Min-Power mode to provide minimum dump load heating, or a Max-Power mode where maximum power is delivered to the dump load. Min-Power mode is typically selected when diversion is used for charge control only and dump load power is not directed towards a useful purpose. Max-Power mode is typically selected when dump load power is directed towards a useful purpose such as heating water. e Max-Power mode may also be used with PV power alone if the user wishes to divert available PV power which is not required for battery charging to a useful purpose. For dump load applications exceeding 20 amps current booster module CBM4070 will support dump loads up to 40 amps. CBM4070 is driven by the auxiliary output of a DUO-Option equipped 3024.

  • Converts Sb3024il(l) Auxiliary Output into 20Amp diversion PWm Charge Controller For Wind or Hydroelectric Generators
  • Provides both MPPT PV Charge in the same unit
  • Simple Plug-in Upgrade
  • Avilable Current Booster module increases diversion Current in 40 amp Increments
  • Full 5 year limited warranty

    A 12/24V MPPT type PV battery charge controller with an auxiliary output which can serve as a 20A load controller. The DUO-Option Diversion Control upgrade converts the 3024’s 20A auxiliary output into a separate 20A diversion type charge controller.
