Product Description
The Steca Solsum-F generation is one of the most successful and most frequently used charge controllers in solar home systems.
With load currents of up to 10 A with automatic switching of 12 V or 24 V, it is optimally suited for devices with an output of up to 240 W.
The circuit board is completely electronically protected and the LED user interface allows easy reading of the battery status at any time.
Large connectors allow easy connection of solar panels, battery and load.
The Steca Solsum F operates as an energy-efficient series controller based on PWM.
