## Description

Morningstar Sunlight Pulse Width Modulation (PWM) solar charge controller with 20A charge rating for off-grid solar systems. It regulates power from the solar array to the battery bank. This controller features an integrated microcontroller for advanced automatic lighting control. It offers 10 customizable lighting options and includes an accurate on-board timer. With a user-adjustable rotary digital switch, you can set the lights to remain ON for 2 to 10 hours or for all-night operation. The unique ON/OFF/ON settings conserve energy by turning the lights on 1-2 hours before sunrise. The timer ensures accuracy within 2 seconds. Easy to set-up, with a convenient test-button feature and LED indicator. The test button allows you to verify correct installation by turning the lights on during the day, while the LED indicates selected lighting option. Its rugged design is made to withstand harsh conditions including seaside environments. This controller uses series PWM with three-stage charging: bulk, absoption, and float. It includes temperature compensation at the controller or at the battery with an optional remote sensor.
