• Includes all the advantages of the SunSaver charge controller. Please refer to the SunSaver product information for more details.


• Unique Lighting Control Features
• Using solar array voltage to determine day and night, the SunLight provides 10 different lighting control options.
• By measuring the length of the night, the SunLight’s ON/OFF/ON options provide the capability to turn on the light at sunset, turn off the light after 3 to 6 hours, and then turn on the light again for 1 or 2 hours before sunrise.
• The length of the night is calculated by taking a moving 4 night average, and thus automatically adjusts for seasonal changes in the length of the night.
• The test button helps the installer by blinking the red LED to confirm correct selection of lighting control option, and also turns on the light for 5 minutes to verify that the light is operating correctly.
• Timer accuracy is within 2 seconds.


• The SunLight is available in 10A or 20A, and at 12VDC or 24VDC


• For solar arrays greater than 20A, the SunLight may be used in parallel with the SunSaver controller (lighting control limited to 20A).
