Morningstar SunKeeper SK-6 PWM Charge Controller

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 efficient power electronics for thermal management and is rated to 70°C/158°F ambient operating temperature .

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
• 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
