The new 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 new designed 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 brand new Solsum works on PWM
as a low loss serial controller.
