The Sunlight Solar Lighting Controller, or SLC, is a solar panel charge regulator for 12V PV systems.   Rated at 20A (240W), it's a bit more powerful than the 10A unit (which we also stock). 

This charger controller has a digital rotary switch for selecting 10 different lighting options. It uses the voltage input to calculate day & night (as well as charge your battery). It can then switch on lighting one or two hours before sunrise and a set number of hours after sunset.  Alternatively, lights can be kept off or on all night.

Perfect for street lights, bus stops and signs. 

    * low voltage disconnect facility  
    * Test button confirms selected lighting option & tests the lights for 5 minutes.
    * battery selection (flooded or sealed)
    * LED indicators for battery charge & startup/load disconnect/control selection
    * reverse polarity protection
    * large screw terminals for simplified connectivity
    * very corrosion resistant
    * dimensions: 168 x 55 x 34mm; 320g.
    * rated solar input of 20A
    * 5-year warranty
    * calculates night length automatically   
    * Wall-mountable   
    * can operate in parallel configuration with other Morningstar Controllers   
    * prevents battery discharge at night. No need for blocking diode.

These controllers provide pulse width modulation (PWM) charging, which can double the life of a battery compared with On-Off charging. This typically sends 30% more solar energy into the battery per day. Average battery State-of-Charge is 90-95% compared to 55-60% for On-Off regulators.
