Morningstar SunKeeper SK-12 12 Amp 12VDC PWM Charge Controller

Morningstar SunKeeper SK-12 12 Amp 12VDC PWM Charge Controller

Manufacturer Part#: SK-12

Morningstar’s SunKeeper SK-12 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.

To withstand the high temperatures at the solar module, the SK-12 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 oil/gas applications.

Features:

• High Reliability & Longer Battery Life - Rated to 70°C to operate in high temperatures at the solar module. More reliable than controllers mounted inside of the junction box. Uses very low on-resistance power MOSFET's. No need to re-rate. Series PWM with 3 stage charging: Bulk, PWM Regulation, & 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.
• Extensive Protections & Outdoor Rated - Fully protected against reverse polarity, short circuit, overcurrent, lightning and transient surges, high temperature and reverse current at night. ETL approved for outdoor use without additional enclosures. Rugged IP65 and UV resistant case. Epoxy encapsulated printed circuit board and watertight connection to the module junction box.
• Hazard Ready & Easy to Install - Specifically designed for solar power systems in the oil/gas industry. Approved for use in Class 1, Division 2, Groups A,B,C,D. Fits standard half inch conduit knock out (PG 13.5, M20) in module junction box. Quickly fastens with included locknut. Wires have fork connectors for easy connection to solar module terminals.
