Energy Management Function
Of Fronius Datamanager 2.0
* Included in Fronius Galvo / Primo / Symo / Eco
Version 1.0, Training and Education, PH
2016, Fronius International GmbH

1 GENERAL INFORMATION
The Energy Management Function on the Fronius Datamanager essentially allows the power produced from the
solar system to “divert” to a load instead of exporting it to the grid.
The Fronius Datamanager comes built-in in the inverter series Fronius Galvo, Primo, Symo, Eco and can be
retrofitted to Fronius IG, IG Plus, and CL. The Fronius Datamanager is available as card or box.
A key feature allows an external load to be turned ON or OFF depending on the amount of power the inverter is
producing or according to the amount of production being consumed on-site.
Using a Fronius Smart Meter (energy meter) in the installation allows the consumption to be taken into account
and therefore a load can be switched on whenever there is surplus power available that can be used on site
instead of feeding it into the grid. This increases the self-consumption ratio. Without the energy meter in the
system loads can be controlled accordingly to the output power of the inverter.
The Energy Management Function puts out one signal. It can be potentially used to switch electric hot water
heater, heat pump, pool pump, air conditioner, bore pump, etc.
This document describes how to use the functionality and setup of the Energy Management Function of the
Fronius Datamanager.
1.1 System design
1.1.1 Switching loads via external relay
The digital output signal of the Datamanager controls an external relay which switches the load. The energy
meter measures the loads in order to calculate the available surplus power.

1.1.2 Switching loads via external relay without energy meter
The digital output signal of the Datamanager controls an external relay, which switches the load. The threshold
to switch ON/OFF can be set accordingly to the output power of the inverter.
Figure 2 –Energy management function on external relay
1.2 Wiring detail
The following diagram shows a typical wiring example using an external relay and an override switch that allows
the additional, manual control of the load.
Figure 3 –Example connection diagram
This circuit consists of an override switch (1) where the load can be switched manually and the power outlet (2), which the
load can be connected to. With the external relay (3) the loads will be switched on/off controlled by the settings of the
Fronius Datamanager (4).
The output on the Datamanager is on I/O port 1 and the Minus pole (or GND on Datamanger 1.0). For further
details see next chapter.

2 FRONIUS DATAMANAGER HARDWARE
2.1 Fronius Datamanager version 2.0
Fronius Datamanager 2.0 has more functions than version 1.0. The new features include the Modbus RTU
(RS4585) communication protocol to connect a Fronius Smart Meter (energy meter) and the built-in WiFi
hotspot, which allows commissioning and adjusting the settings wirelessly.
Fronius Datamanger Version 2.0 was built-in in Fronius Galvo and Symo inverters until end of 2014. Inverters
with a serial number 25490000 and higher are equipped with version 2.0. It is built-in in all Fronius Primo and
Eco units.
Figure 4 - Datamanager 2.0 –card & plug
Switching capacity of the digital output of the Fronius Datamanager 2.0 plug-in card: 3.2 W, 10.8/12.8 V
10.8 V: Fronius IG, Fronius IG Plus, Fronius IG Plus V, Fronius CL, Fronius IG 300–500
12.8 V: Fronius Galvo, Fronius Primo, Fronius Symo, Fronius Eco
3 SOFTWARE SETUP AND CONFIGURATION
3.1 Fronius Datamanager interface
The settings can be adjusted via the Datamanager website (webserver is built-in) by following these steps:
/ Activate the Wi-Fi hotspot* on the Datamanager card (inverter) or Datamanager Box 2.0
/ Connect your computer/tablet/smartphone to the Datamanager’s WLAN hotspot*. Or connect a LAN cable to
the computer.
/ 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 on the Datamanager’s web interface (also called PV Inverter Homepage)
3.2 Energy manager settings
3.2.1 Datamanger software version 3.3.0 and higher
Before setting the thresholds to switch ON/OFF, the following points should be considered
/ Approx. base load of the site should be measured (energy meter) or calculated.
/ PV system size known
/ Power requirement of the device to be controlled with the Energy Management Function
I/O 1
–
df

To adjust the settings follow these steps:
/ Go to the Datamanager Web Interface (For instructions on how to go to the Datamanager Web interface see
chapter ‘Datamanager Web interface’ in the apendix.)
/ Go to “Settings”
/ Select the “ENERGY MANAGER” tab (see Figure 10)
1. Activate Energy Management function by selecting “Controlling: by power production”.
If a Fronius Smart Meter is included in the system, the setting “by power surplus (in case of feed-in
limits)” can be chosen. The treshholds to switch ON/OFF are then activated according to site surplus
energy.
2. Set “Thresholds on:” to level of which the relay should be switched on
3. Set “Thresholds off:” to level of which the relay should be switched off
4. Set “Minimum duration per on-signal” (if required)**
5. Set “Maximum duration per day” (if required)
6. Click “Save” for the settings to be activated
If the load needs to be switched ON every day for a certain amount of time, then apply the following settings:
1. Tick “Desired duration” to activate a minimum time to switch on (if required)
2. Set a desired daily ON duration in minutes (“per day”)
3. Set the time of day when the desired duration should be completed by (“is to finish by”)
4. Click “Save” for the settings to be activated

3.2.2 Datamanger software version 3.2.2 or smaller
Note: Datamanager software version 3.2.2 and smaller have less features. To get the full functionality make a
software update as described in chapter 5.2 Software Update of Datamanager.
To adjust the settings on Datamanger software version 3.2.2 or smaller follow the steps:
1. Activate function by ticking “Approved”
2. Set “Operating point ON” to level of which the relay should be switched on
3. Set “Operating point OFF” to level of which the relay should be switched off
4. Set “Minimum ON” time (if required).
5. Click “Save” for the settings to be activated
3.3 Remote control
It is possible to remotely adjust the settings of the Datamanager from any PC connected to the same LAN (local
network). Therefore it is required to use a “Static IP’ address in the network settings of the Datamanger. For a
static IP adress ask your local IT administrator. This IP address can then be saved in the browser for easy
access to the Datamanager interface. Some new network routers (Wi-Fi router) also allow to use the URL
http://datamanager/.
To get remote access outside of the LAN an external IP address is needed. Ask your IT administrator or internet
provider for assistance.
** Some loads require to be ON for a minimum time (for example an air-conditioner)
*** Cannot be chosen if a S0 meter is placed in the consumption path.
Chose the ON/OFF threshold
either a value for ‘Feed in’ or
‘Consumption’***.
