Steca Solsum F
6.6F, 8.8F, 10.10F
The Steca Solsum F-Line continues the huge success of one of the
most used SHS controllers. With a power range of up to 10 A at
automatically recognized 12 V or 24 V it fits to a system sizes of
maximum 240 W.
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.
