Steca Solarix
2401, 4401
The solar charge controllers Steca Solarix 2401 and 4401 are
optimally suited for inverter systems. The controller combines
basic solar charger functions with a 40 A high-performance
charge controller. It is available as 12 V / 24 V and 48 V system.
This makes the solar charge controller very cost effective.
The load current is limited to 10 A. The charging processes
are based on the voltage level, which can be individually set
with the help of four buttons behind the front casing.
