Regulator Steca Solsum 8.8 F

The Regulator Steca Solsum 8.8 F It continues with the great success of one of the most used load regulators in the domestic solar energy systems. It is especially suitable for the application of systems with a power of up to 240 W with a power range of up to 10 a and with an automatic switching of 12 V or 24 V.

Regulator STECA SOLSUM F 6.6 F, 8.8 F, 10.10 F

  • Extremely intuitive load Controller
  • LED indicator
  • Automatic Battery voltage detection
  • Professional load Monitoring
  • Low consumption

The printed circuit board is completely electronically protected and the LED display allows you to read the battery status easily. The connectors allow a simple connection with the solar panels, the battery and the load. The Steca Solsum F functions as a series regulator by modulating the duration of efficient energy pulses.
