The Steca Solsum F-Line continues the huge success of one of the most used SHS controllers. With a power range of up to 10A at automatically recognized 12V or 24V it fits to a system sizes of maximum 240W. The circuit board is completely electronically protected and with the LED user interface it is easy to check the battery state of charge at any time. Large terminals guarantee a simple connection of solar panels, battery and load. The Steca Solsum F works on PWM as a low loss series controller.
