4.4 Making changes to the system
Master and slave(s) are identical inverters. Their function in the system is deter-
mined by the connection to the parallel box:
Master: "Solarix Inverter Master" data input and "Master L/N" voltage input
Slave(s): "Solarix Inverter Slave" data input and "Slave L/N" voltage input
WARNING
Danger of explosion from sparking! Danger of electric shock!
Plugs and cables must not be disconnected when voltage is present!
X
Before pulling out plugs or disconnecting cables make sure that no loads are
connected and the inverters are disconnected from the battery.
X
The cables pre-fitted to the inverters must not be extended.
4.4.1 Replacing inverters
Proceed as follows when replacing the master or a slave:
X
Make sure that no loads are connected and the inverters are disconnected
from the battery.
X
Pull out the RJ45 plug at the relevant data input.
X
Open the cover on the parallel switch box.
X
Disconnect the input of the relevant master or slave at the parallel switch
box.
X
Connect the new master or slave, as described in Section 4.2.
4.4.2 Using a slave as the master
If the master fails, a slave can be used as the new master.
X
Make sure that no loads are connected and the inverters are disconnected
from the battery.
X
Pull off RJ45 plugs of all data inputs.
X
Open the cover on the parallel switch box.
X
Disconnect all the cables at the parallel switch box.
X
Connect the reconfigurated system as described in Section 4.2.
5 Operation
In parallel operation the power supply is regulated by the rotary switch on the
master, see the Steca Solarix PI operating instructions.
The rotary switches at the slaves do not have any function. However, they must
be in the “Off” position because otherwise the slaves may eventually become
operational unintentionally.
5.1 Rotary switch settings
Master Slave(s) Inverter state
Off Off
Master and slaves switched off
Standby Off Load-dependent response of master and slaves, where
applicable
On Off Master always switched on, slaves switched on as
required
All On Off Master and slaves always switched on
This setting is recommended for high performance
devices (at the performance limit), e.g. for operating a
washing machine
