Introduction
Up to 4 Steca Solarix PI 550(-L60) / PI 600(-L60) / PI 1100(-L60) / PI 1200(-L60) stand-
alone inverters can be operated in parallel with the PAx4 parallel switch box on
115 V or 230 V (see table below). One inverter works as a master, the others as
slaves. The PAx4 has 2 outputs.
The PAx4 serves as a communication interface between inverters and a
Tarom
or Power Tarom type charge controller. This enables the PV system to be SOC
1)
controlled.
