The Steca PR Night is a solar lighting controller (up to 300 Wp) for automatic lighting control in various applications such as PV powered streetlights, bus shelters or billboard lighting. The controller detects day and night using the PV array. An entirely new feature is the integrated clock that sets itself automatically based on the levels of brightness detected during a 24 hour day. There are two major options:
• the light switches on after sunset • the light switches on before sunrise
