SunKeeper

The SunKeeper™ is a compact PWM charge controller designed to deliver reliable battery charging for small off-grid solar systems. By regulating the power delivered from the solar module, it helps maximize battery life while providing dependable performance in remote applications.
Its weather-resistant, epoxy-encapsulated design mounts directly to a solar module junction box for simplified installation and long-term durability in outdoor environments.

Key Features
- 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.
