Solar freezer
Steca PF 166
Solar freezer
The Steca PF166 is the most energy saving DC fridge and
freezer combination for all DC and solar applications, also
for medical clinics and medicine cooling. The device can
be used either as a fridge or as a freezer. The user can al-
so fully programme the unit and adjust the temperature
inside the cooling compartment individually.
Due to the latest A++ cooling technology in combinati-
on with optimised electronic regulation and compressor
speed control Steca provides optimal use of energy. This
leads to cost savings as the size of the necessary PV off-
grid system can be reduced in comparison to other DC
fridges.
User friendliness, highest quality, reliability and mainte-
nance free long life time are important characteristics of
this innovative product. The device can either run with 12 V
or 24 V input voltage.

Steca fuel cells
Efoy 600, 1200, 1600
The Efoy fuel cells are direct methanol fuel cells
(DMFC), which can run in combination with a battery.
The fuel cells can be fully integrated into a Steca hybrid
system as a reserve generator. In case of extra energy de-
mand, the fuel cell is automatically started and the batte-
ry is charged. The cell is delivered together with the fuel
tank, and can be connected directly to a 12 V battery. It
is designed for small systems which require their energy
supply to be extremely reliable.
Functions
Easy to integrate into a Steca hybrid system
Plug & play solution
Liquid tank for methanol allows fuel to be managed
easily
Display
LEDs to display system status
Displays the Ah fault messages and the charging
process
