Sunkeeper SK-6 and SK-12
Junction Box Mounted Solar Controller
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.
The SunKeeper is available in a 6 amp or 12 amp version
(both at 12 volts DC). To withstand the high temperatures at the solar module,
the controller has been designed using extremely efficient power electronics
and is rated to 70°C. The SunKeeper is also certified for use in Class 1,
Division 2 hazardous locations, making it an ideal controller for solar powered
Key Features and Benefits:
- High Reliability -
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 - 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.
- 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
- Rated for Hazardous Locations - Specifically
designed for solar power systems in the oil/gas industry. Approved for use
in Class 1, Division 2, Groups A,B,C,D.
- 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.
