Compact “point of use” design that mounts directly to the solar
module junction box or module frame, eliminating the need for an
additional controller housing. SunKeeper is the ideal solution for
economically providing regulated output directly from the solar
module, to maximize battery life in small solar power applications.
It’s especially well-suited for oil & gas applications, approved for use
in hazardous locations: Class 1 Division 2, Groups A-D.
SunKeeper is epoxy encapsulated and sealed in an IP65 rated
UV-resistant case and approved for outdoor use with no additional
enclosure required. By mounting directly to the module junction
box and wiring through the junction box knockout, the connection
remains weather-proof. To withstand the high temperatures at the
solar module, the controller incorporates extremely efcient power
• Rugged design—approved for outdoor use without an additional
enclosure. IP65 rated with UV-resistant case; epoxy encapsulated
electronics and watertight connection to junction box
• High temperature rated—to 70C for operation in high temperatures
at the solar module; no need to de-rate
• Ideal for Oil/Gas applications. Approved for use in hazardous
locations: Class 1, Division 2, Groups A-D
• Available in both 6 Amp and 12 Amp versions (both at 12 volts DC)

SUNKEEPER™ JUNCTION
BOX-MOUNTED SOLAR
CONTROLLER
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 cur-
rent at night.
• Longer Battery Life
Series PWM with 3 stage charging: bulk, PWM regulation and
oat. Includes temperature compensation at the controller or al-
ternatively at the battery when using optional remote temperature
sensor. Able to charge a zero voltage battery.
• Rated for Hazardous Locations
Specically designed for solar power systems in the oil/gas industry.
Approved for use in Class 1, Division 2, Groups A-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 night-
time 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
“This is a great little unit…an outstanding
charge controller”
