Morningstar SunKeeper 12A PWM Charge Controller

The Morningstar SunKeeper SK-12 is a 12A PWM solar charge controller designed for 12V battery systems, mounting directly to the module junction box for a compact, weatherproof install. It uses series PWM 3-stage charging (bulk, PWM, float) with 14.1V regulation and 13.7V float at 25°C. The IP65 epoxy UV-resistant enclosure withstands -40°F to 158°F and 100% humidity, and it can even charge a zero-voltage battery.

Key Features:

• 12A PWM charge controller, 12V system
• Series PWM 3-stage: bulk, PWM, float
• Regulation 14.1V / float 13.7V at 25°C
• Max PV input voltage 30 VDC
• Voltage accuracy ±150 mV, charges 0V battery
• Self-consumption 7 mA charging, 2 mA night
• IP65 epoxy UV-resistant enclosure, -40°F to 158°F
• Reverse polarity, short circuit and surge protection
• Class 1, Division 2, Groups A-D hazardous locations
• CE, CSA C22.2 No. 213, UL 121201, 5-year warranty

Ideal for remote 12V solar applications where a rugged, junction-box-mounted controller is needed, including hazardous Class 1, Division 2 locations. It suits telecom, monitoring and off-grid loads, complies with the U.S. National Electric Code, and accepts #14 AWG wiring with #8 fork connectors.
