Solarix Sinus
550 I, 550 RI, 900 I, 900 RI
The Solarix series of sine wave inverters has proved it self
in over 10,000 applications. These devices have been
used throughout the world. With its compact construc-
tion and optionally integrated solar charge controller, this
‘plug & play’ solution is easy to install. A switch on the
front of the device enables the user to choose between
automatic load detection mode, continuous operation or
sleep mode, therefore considerably reducing the standby
consumption. This is particularly important for stand-alo-
ne systems.

Communication with Tarom charge controllers
A further Solarix PI innovation is the communication with
the solar charge controllers from the Steca Tarom and Po-
werTarom series. A data connection to the charge con-
troller can be created via the PAx4.
In this case, the inverter connected directly to the battery
communicates the amount of energy that has been with-
drawn to the solar charge controller. The controller is thus
able to calculate the correct state of charge (SOC). This
means that these systems no longer need to be switched
to voltage-controlled operation or an additional current
shunt.
If the switch-off threshold of 30 % SOC is reached, the
Solarix PI receives a signal from the solar charge control-
ler and subsequently switches itself off in order to protect
the battery from deep discharge. It turns itself back on
again once the SOC has reached the 50 % mark.
