Smart Meter Manual

Multi meter sys-
tem - Fronius
SnapINverter
If several Fronius Smart Meters are installed, a separate address must be set for each
one (see Set the address of the Fronius Smart Meter on page 15). The primary meter
always receives the address 1. All other meters are numbered consecutively in the
address range from 2 to 14. Different Fronius Smart Meter power categories can be used
together.
IMPORTANT!
Use no more than 3 secondary meters in the system. To avoid interference, it is recom-
mended to install the terminating resistors according to the chapter Terminating Resist-
ors on page 16.
Position of the primary meter in the consumption branch. *Termination resistance R 120 Ohm
Position of the primary meter at the feed-in point. *Termination resistance R 120 Ohm
The following must be observed in a multi meter system:
- Each Modbus address is assigned only once.
- Place the terminating resistors individually for each channel.
Modbus parti-
cipant - Fronius
GEN24
The inputs M0 and M1 can be freely selected. A maximum of 4 Modbus participants can
be connected to the Modbus terminal on the inputs M0 and M1.
IMPORTANT!
Only one primary meter, one battery and one Ohmpilot can be connected per inverter.
Due to the high data transfer of the battery, the battery occupies 2 subscribers.
