SunLight™
Charge Controller

Morningstar's SunLight is the world's leading solar
lighting controller. We have combined all the advantages of our SunSaver
charge controller with some unique lighting control features.
- 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).
