3.4.4 Addressing
Every inverter must be assigned its own unique address for the communication
between the inverters and the StecaGrid Vision to function correctly. The factory
setting for the address is
1
. This must be changed if the system has more than one
inverter. The following applies:
• The address is set via two rotary switches on the inverter interface card (see
figure below):
–
Left rotary switch: tens
–
Right rotary switch: units (see also the labels next to the rotary switches on
the circuit board)
• Only the following addresses may be set:
–
StecaGrid Vision: addresses 1 – 20
–
Solar-Log: addresses 1 – 99 (maximum, depending on device type)
–
WEB’log: addresses 1 – 31
• We recommend assigning addresses using an incrementing sequence from
the first to the last inverter. This makes the relevant inverter easy to iden-
tify when reading messages from the StecaGrid Vision that contain address
numbers.
• The inverter addresses are entered into the StecaGrid Vision the first time it is
switched on; see the StecaGrid Vision manual.
