7.2 Expansion possibilities
Up to 4 Steca PI inverters can be connected in parallel via a parallel switch box
when the system is extended or when additional consumer devices are connected.
The parallel switch box also allows communication with Steca Tarom 4545(-48)
or Steca Tarom MPPT 6000-M charge controllers (software update required). This
allows the PV system to be controlled depending on SOC (State of Charge).
Please refer to the separate PA Link1 operating instructions for more informa-
tion.
