Note
The 25000xi - 33000xi Kaco inverter models are shown as 3 independent inverters in the Solar-Log™. If,
for example, such inverters are available, give them addresses 1 and 2. In the Solar-Log™ the inverters
will be shown internally as 1.1 / 1.2 - 2.1 / 2.2 etc.
Note
A maximum of 32 inverters can be connected per RS485 bus.
