1 GENERAL

Fronius Smart Meters (single phase or 3-phase) are energy meters that work in conjunction with the Fronius

Datamanager V2. The Smart Meter must be connected to the Fronius Datamanager V2 which comes built-in to

all Fronius SnapINverters (Galvo, Primo, Symo and Eco), and can be retrofitted into all other Fronius inverters.

Using a ModBus RTU / RS 485 connection protocol, the smart meter can be utilised to monitor consumption

data or in order to limit the export of a PV system. They can measure current/voltage/energy/reactive

power/apparent power in total or per line.

Once a battery is added to an installation a Smart Meter is mandatory. If the installation is single or dual phase

a 3-phase Smart Meter can be used.

This document describes how to do install and setup the Fronius Smart Meter.

1.1 Requirements

/ Important! The Fronius Smart Meter cannot be used in combination with the Fronius Datamanager Version 1.

/ The Fronius Datamanager V2 needs to have a software version of V3.3.6-13 or greater. (For details how to

upgrade the firmware see chapter 1.3 Software update of Fronius Datamanager).

/ The Datamanager needs to be set up before executing the meter settings. For information on how to set up

the Fronius Datamanager please see the Fronius inverter or the Fronius Datamanager manual (for Fronius

Galvo/Symo/Primo/Eco):

1.2 Where to put the Fronius Smart Meter

Due to the setup of installations in Australia, in most cases the meter will be put into the feed-in path (diagram

1). If the PV system is connected to a sub board it’s most likely to achieve the load measurement by having the

meter in the feed-in path. In rare occasion it can be put into the consumption path (diagram 2).

/ Feed-in point

In this setting the solar generation passes through the meter as well as the site load.

The meter in this scenario does not measure the solar production, only the consumption.

1.3 Software update for Fronius Datamanager

The easiest way to update the Fronius Datamanager is to use the Datamanager’s web interface. To update

your software access the web interface follow the steps below:

/ Activate the Wi-Fi hotspot on the Datamanager card (inverter) or Datamanager Box V2

/ Connect your computer/tablet/smart phone to the Datamanager’s WLAN hotspot

/ Open a web browser and go to http://192.168.250.181 or http://datamanager/

Alternatively you can use Fronius SolarWeb App for tablet or smart phone and go to ‘Settings’ and click

‘PV Inverter Homepage’

/ Select Firmware update The Datamanager web interface (PV Inverter Homepage)

Go to ‘Firmware update’’

2 INSTALLATION AND SETUP OF THE FRONIUS SMART METER

2.1 Schematics and Wiring

Diagram 3 shows the system configuration

(Diagram 3)

Please note:

/ Wiring between meter and inverter should use CAT5 or CAT6 cable (LAN cable)

/ Connection is a data line for Modbus RTU / RS485 using screw terminals on the meter

/ Maximum distance: 300 m (980 feet)

Meter connection on the Datamanager V2

The meter needs to be connected to the Datamanager’s binary output, as shown in diagram 4.

Modbus termination switch on the Datamanager

The internal bus termination 120-Ohm resistance (for Modbus RTU) needs to

be switched to ON to be activated.

Please Note:

The termination resistance must be activated for the first and last device in an

RS-485 bus.

* The 120 Ohm terminating

resistor comes with the meter

*** Please note that the

connections 33, 34, 35 on the

Fronius Smart Meter are in

reverse order to those shown

in diagram 6!

* The 120 Ohm terminating

resistor comes with the

meter

** It is important to connect

the Neutral.

2.2 Activate the meter on the Fronius Datamanager web interface

The dynamic power reduction can be set on the web interface of the Fronius Datamanager as shown below.

/ On the Datamanager web interface select Settings

/ Before it is possible to enter the METER settings a service password is required. If no service password has

been set, it needs to be created first!

Go to ‘METER’ to do the

relevant settings.

Important! If no service

password has been set:

Choose a service password

under PASSWORDS.

Go to ‘Settings’.

/ Choose the type of meter.

/ Choose the installation location.

For further explanations on feed-in path and consumption path see chapter 1.2 Where to put the Fronius Smart

Meter

/ The meter is activated once you get the following message. Click OK!

Done!
