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 sta-
te of charge at any time. Large terminals guarantee a simple
connection of solar panels, battery and load. The Steca Sol-
sum F works on PWM as a low loss series controller.

Steca PR
PR 0303, PR 0505
The Steca PR 0303 and PR 0505 solar charge controllers are
optimally suited for use in small solar home systems with mo-
dule currents up to 5 A.
A 75 Wp module can be connected, which easily allows ope-
ration of lamps, radios and a small television. All loads can be
switched off using the manual load switch on the controller.
The extremely low own consumption makes the Steca PR es-
pecially suitable for professional applications in telecommu-
nications and traffic management technology. Since this is a
serial controller, it is extremely flexible in the type of power
source that can be connected. The electronic fuse makes the
controller completely maintenance-free and robust.
