SOLAR CHARGE CONTROLLERS

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.

___Full circuit board protection with LED display for simple

recognition of battery status. Various connections make it possible

to connect easily to solar panels, battery and load. The Steca Solsum

F works on PWM as a low loss series controller.
