Steca PR Night
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
Certificates
- approved for Worldbank funded projects in Laos
- Made in Germany
- manufactured in a
- DIN EN ISO 9001:2000 and
- DIN EN ISO 14001 facility
Features
- PWM shunt battery charging
