    • SunKeeper™ solar controller provides a low cost regulated output directly from the solar module to maximize battery life in small solar power applications. The SunKeeper is epoxy encapsulated and rated for outdoor use. By mounting directly to the module junction box and wiring through the junction box knockout, the connection is weather-proof. This eliminates the need for an additional housing for the controller.

    “This is a great little unit…an outstanding charge controller”

    How to Buy

    Key features and benefits

    • High Temperature Rated
      Rated to 70°C to operate in high temperatures at the solar module.
      More reliable than controllers mounted inside the junction box. Uses
      very low on-resistance power MOSFET’s. No need to re-rate.
    • Outdoor Rated Rugged Design
      ETL approved for outdoor use without an additional enclosure. Rugged
      IP65, UV resistant case. Epoxy encapsulated printed circuit board and watertight connection to the module junction box.
    • Ideal for Oil/Gas Applications
      Specifically designed for solar power systems in the oil/gas industry.
      Approved for use in Class 1, Division 2, Groups A,B,C,D.
    • Extensive Electronic Protections
      Fully protected against reverse polarity, short circuit, overcurrent, lightning and transient surges, high temperature and reverse current at night.
    • Longer Battery Life
      Series PWM with 3 stage charging: bulk, PWM regulation and float.
      Includes temperature compensation at the controller or alternatively at
      the battery when using optional remote temperature sensor. Able to
      charge a zero voltage battery.
    • More Information
      Bi-color LED is easy to read from the ground when the solar module
      is pole-mounted. Indicates solar charging, regulation, normal nighttime operation and any controller or system faults.
    • Easy to Install
      Fits standard half inch conduit knockout (PG 13.5, M20) in module
      junction box. Quickly fastens with included locknut. Wires have fork
      connectors for easy connection to solar module terminals.
