1. GENERAL
Fronius Smart Meters are Energy Meters which can be used to measure
consumption data of a site or for export limitation of a PV system with the
Fronius SnapINverter or GEN24 inverters.
The meter measures the energy flow to the loads or to the grid and feeds
the information to the Fronius inverter via ModBus RTU/RS485. On the
SnapINverter, this communication interface is the Datamanager 2.0 which
is installed as standard in Fronius Galvo, Primo, Symo and Eco
SnapINverter. Light versions are an exception. Datamanager 2.0 can also
be retrofitted to all older Fronius inverters. In the GEN24 inverters, the necessary communication interface is
always built in as standard (there is no light version).
This document describes how to install and set up only the 63A-1 single phase or 63A-3 3phase Fronius Smart Meter range. Please use the below links if using a different model of
Fronius Smart Meter.

1.1 Location of the Fronius Smart Meter
With the Fronius Smart Meter there are 2 possible energy paths/ locations where it can be installed.
In almost all cases, the Fronius Smart Meter will be installed in the feed-in path. This is also the default setting
in the Datamanager’s METER section.

2. INSTALLING AND ACTIVATING A FRONIUS SMART METER
2.1 Schematics and Wiring Requirements
/ Wiring between Fronius Smart meter and inverter should use a CAT5 or CAT6 cable.
Important: To be compliant with the AS3000 standards, it is recommended to have the CAT5/CAT6 cable
in a heat shrink tubing (probably 10mm) when it enters the switchboard part or alternatively use a 240V
rated CAT5/CAT6 cable (e.g. Clipsal CBUS cable).
/ Connection is a data line for Modbus RTU / RS485 using screw terminals on the meter
/ Maximum distance: 300 m (980 feet)
/ Use a single core per terminal connection between Fronius Smart Meter and the inverter. For D+ and D- use
the single cores from the same colour (e.g. D+ is orange/white, D- is orange)
Meter connection on the Datamanager 2.0
The meter needs to be connected to the Datamanager’s terminal block using terminals D+, D- and -.

Modbus termination switch on the Datamanager 2.0 and the GEN24 inverter:
The internal bus termination 120-Ohm resistance (for Modbus RTU) needs to
be switched to ON. This switch is set to ON by default.
Please Note:
The termination resistance must be activated for the first and last device in an RS485 bus.

3. FRONIUS SMART METER TROUBLESHOOTING
4.1 – Timeout, meter not detected
If the Fronius Smart Meter is not being detected in the Technician wizard or PV Inverter Homepage try the
following steps in order. After each step try to activate the meter again
1) Restart the inverter, shutdown both AC and DC to the inverter to switch it off and then power it back up.
Reconnect to the wifi access point and attempt to activate the meter again.
2) Check that the 120 Ω resistor is installed correctly across the meter terminals as per the wiring
diagrams in Section 2.1.
3) Confirm that the cable used between smart meter terminals and inverter terminal block are properly
terminated.
4) Confirm that the RS485 wiring between meter terminals and inverter terminal block are correct as per
the wiring diagrams in Section 2.2.
5) If cable is short enough complete a continuity test on the cores used to ensure no breaks in the cable
6) Update the GEN24 inverter/Datamanager 2.0 software. After software update restart the GEN24
inverter/Datamanager 2.0 as per Step 1 of this section. Refer to our update guide for more information:
https://www.fronius.com/~/downloads/Solar%20Energy/Technical%20Articles/SE_TEA_Quick_guide_H
ow_to_update_Fronius_Datamanager_firmware_EN_AU.pdf
4.2 – Data is not accurate in Solar.web
1) Meter is set in the incorrect path compared to actual installation. Refer to Section 1.1 of this guide and
correct as per the above set up steps in 2.2.1 and 2.2.2.
2) Meter is installed in the wrong location in the switchboard. It must be installed after the Normal Supply
Main switch and before the rest of the site loads including the Solar Supply Main Switch for feed in
path. Refer to the single line diagrams in Section 1.1
3) If getting minimal load consumption values the meter may be in parallel with the Normal Supply Main
Switch. Ensure they are in series or the meter will be mostly bypassed.
