    Detailed Description:

    Morningstar's SunGuard SG-4 is the world's leading single module controller.
    We have combined all the advantages of our SunSaver charging circuit with less expensive packaging to provide an economical controller for small PV systems.
    Morningstar’s SunGuard is the most advanced small, economical solar charge controller on the market today.

    The MorningStar SunGuard is a fully epoxy encapsulated outdoor rated 4.5A "ice cube" sized 12V PWM charge controller.
    It has built-in temperature compensation, lightning protection and easy 4-wire hookup.
    The SunGuard's regulation voltage is set at 14.1 (best for sealed or gel batteries) and is not adjustable for battery type like MorningStar's other controllers.
    It's dimensions are 2.5" x 2.0" x 1.5" and it weighs just 3 oz.

    INSTALLATION


    1. MorningStar SunGuard can be mounted in any position. It is best to mount to a vertical surface and allow space for air flow through the controller.


    2. First connect the Battery BLACK wire (negative) to the battery. Use either black wire since they are connected together inside the controller.


    3. Connect the RED Battery positive wire to the battery.


    4. Connect the Solar array using the other BLACK wire and the YELLOW Solar positive wire. Be very careful not to short circuit the solar array, or the controller will be damaged.


    5. SunGuard prevents reverse current leakage at night, so a blocking diode is not required in the system.


    6. A negative earth ground at the battery is recommended for most effective lightning protection.


    7. SunGuard can be mounted outdoors. Do not expose to ambient temperatures above 60°C. Make sure that water will drain from inside the case.
