SINE WAVE INVERTERS
Steca Solarix PI
500-12, 550-24, 1100-24, 1500-48
The new generation of sine wave inverters, Steca Solarix PI,
demonstrates robustness. Existing safety features have also been
made more customer-friendly and robust. The new generation of the
Steca Solarix PI possess different technical properties to predecessor
models and may not be suitable to replace these.
___In developing the Solarix PI sine wave inverter, Steca has brought
about some innovations. In particular these include the ability to
connect all Steca Solarix PI models in parallel, the innovative
operating concept using a single rotary switch and the electronic
fuse. Furthermore, many years of experience have come into play for
deploying these inverters specifically in photovoltaic systems. This
comes through, for instance, in the way that a most diverse range of
appliances is provided with a low operating consumption and a
stable energy supply.
___The power of the new generation Steca Solarix PIs is only
extensible with the new parallel connection box Steca PA Link1.
Mixing older generation Steca Solarix PIs and new generation Steca
Solarix PIs is not possible.
