    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.

    Current Booster Module

    The Current Booster Module (CBM) is an optically isolated high current MOSFET switch. The CBM can be used to greatly increase the load switching capability of Solar Boost charge controllers with load control outputs. The charge controller load control output serves as the input control signal to the CBM and the CBM provides all high current switching for the load.

    The CBM output turns on when a 3 – 32VDC signal is present on it’s input terminals. Input to output optical isolation allows the output to serve as either a low side switch or high side switch.The CBM can also serve as a PWM power driver for the Solar Boost 3024 DUO-Option wind/hydroelectric diversion charge control system. Up to 70 amps can be switched in a DC on/o application or up to 40 amps in a 3024 DUO-Option PWM diversion application.
