11 GreenWay™ installation & operation manual 0410 MKTG-IM-GREEN-002
Q: Does aiSUN™ have a timeclock inside?
A: No, aiSUN™ does not have a “timeclock”, instead it uses the regular sun rise and sun set it detects to
determine when night is occurring and for how long. By averaging 10 nights of sunrise and sunset data the
CPU accurately determines length of night and when sunrise and sunset occur.
Q: What happens during daylight savings time?
A: Since aiSUN™ performs all of its timing based on sunrise and sunset daylight savings time has no impact
on the CPU. Daylight savings time is a clock change to accommodate having daylight hours align with
certain times of the day, despite what the clock says, when the sun set aiSUN™ turns on the solar light.
Q: Can I reprogram aiSUN™ to work a different way?
A: While it is possible to have aiSUN™ reprogrammed, it is important to consult with SOL Inc about what
operating modes are available. Solar lights can sometimes run longer or brighter, however this typically
requires a larger solar panel and more battery reserve to provide more light, longer. These types of changes
are costly but are possible, contact SOL Inc.
Q: What does aiSUN™ stand for?
A: ai stands for adaptive intelligence, SUN indicates that aiSUN™ is for solar charging.
