Steca PR Night

PR 0606N, PR 1010N


The Steca PR Night is designed to operate automatic lighting at night and is suitable for solar systems with up to 300 Wp module output.

That makes this controller particularly suitable for street lamps, bus stops, display lighting and similar applications. The charge controller recognises real solar time via the solar module. This integrated clock can be used to set how long after dusk or how many hours before sunrise the light is switched on or off.
