One of Steca’s bestsellers are the photovoltaic controllers of the Solsum C series which are used in small solar home systems with a 5 to 10 Amp solar charging and load current capacity (up to 240Wp). The Solsum C series was launched in 2004 as a redesign of the Solsum X series. The C series advantages are large connection terminals, fully covered PCB and a easy to understand display. The electronic board uses automized through hole technology for easy local maintenance.
The Steca PR Night is designed for operating automatic night light systems and is suitable for solar systems of up to 300 Wp module
output. This controller is thus especially suitable for streetlights, bus stops, advertising lighting and other similar applications. The charge controller determines the actual solar time via the solar module. This integrated clock can be used to define how long after sunset, or before sunrise, the light is to be switched on or off.
