The Steca Solsum-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 bat-

tery status. Various connections make it possible to connect easily to solar

panels, battery and load. The Steca Solsum works on PWM as a low loss

series controller.
