Environmental conditions
Operation or storage of the device outside the stipulated area will be deemed as not in accordance with the intended purpose. The manufacturer shall not be held liable for any damage arising from such usage.
Qualified service engineers
The servicing information contained in these Operating Instructions is intended only for the use of qualified service engineers. An electric shock can be fatal. Do not perform any actions other than those described in the documentation. This applies even if you are qualified to do so.
All cables and leads must be secured, undamaged, insulated and adequately dimensioned. Loose connections, scorched, damaged or inadequately dimensioned cables and leads must be immediately repaired by authorised personnel.
Maintenance and repair work must only be carried out by authorised personnel.
It is impossible to guarantee that bought-in parts are designed and manufactured to meet the demands made of them, or that they satisfy safety requirements. Use only original spare parts (also applies to standard parts).
Do not carry out any modifications, alterations, etc. to the device without the manufacturer's consent.
Components that are not in perfect condition must be replaced immediately.
Noise emission values
The maximum sound power level of the inverter is specified in the Technical Data.
The device is cooled as quietly as possible with the aid of an electronic temperature control system; this depends on the amount of converted power, the ambient temperature, the level of soiling of the device, etc.
It is not possible to provide a workplace-related emission value for this device because the actual sound pressure level is heavily influenced by the installation situation, the power quality, the surrounding walls and the properties of the room in general.
EMC measures
In certain cases, even though a device complies with the standard limit values for emissions, it may affect the application area for which it was designed (e.g. when there is sensitive equipment at the same location, or if the site where the device is installed is close to either radio or television receivers). If this is the case, then the operator is obliged to take appropriate action to rectify the situation.
Disposal
To comply with the European Directive 2012/19/EU on Waste Electrical and Electronic Equipment and its implementation as national law, electrical equipment that has reached the end of its life must be collected separately and returned to an approved recycling facility.

General
Device concept
Device design:
| (1) | Housing lid |
| (2) | Inverters |
| (3) | Mounting bracket |
| (4) | Connection area incl. DC main switch |
| (5) | Data communication area |
| (6) | Data communication cover |
The inverter converts the direct current created in the solar modules into alternating current. This alternating current is fed into the public grid synchronously with the grid voltage.
The inverter has been developed exclusively for use in grid-connected photovoltaic systems; it is impossible to generate energy independently of the public grid.
The inverter automatically monitors the public grid. In the event of abnormal grid conditions, the inverter ceases operating immediately and stops feeding power into the grid (e.g. if the grid is switched off, if there is an interruption, etc.).
The grid is monitored by monitoring the voltage, monitoring the frequency and monitoring islanding conditions.
The inverter operates fully automatically. As soon after sunrise as there is sufficient energy available from the solar modules, the inverter starts monitoring the grid. When insolation has reached a sufficient level, the inverter starts feeding energy into the grid.
The inverter operates in such a way that the maximum possible amount of power is obtained from the solar modules.
As soon as the power available has fallen below the level at which energy can be fed into the grid, the inverter disconnects the power electronics completely from the grid and stops running. It retains all its settings and stored data.
If the inverter becomes too hot, it automatically reduces the current output power in order to protect itself.
Reasons for the inverter becoming too hot include the ambient temperature being too high or inadequate heat dissipation (e.g. if it is installed in a switch cabinet without suitable heat dissipation).

Data communication and Fronius Solar Net
Fronius Solar Net and data interface
Fronius Solar Net was developed to make system add-ons flexible to use in a variety of different applications. Fronius Solar Net is a data network that enables multiple inverters to be linked up using system add-ons. | |
It is a bus system that uses a ring topology. One suitable cable is sufficient for communication between one or several inverters that are connected on the Fronius Solar Net using a system add-on. | |
Similarly, every inverter on the Fronius Solar Net must be assigned a unique number. | |
Fronius Solar Net automatically recognises a wide variety of system add-ons. | |
In order to distinguish between several identical system add-ons, each one must be assigned a unique number. | |
More detailed information on the individual system add-ons can be found in the relevant operating instructions or on the internet at http://www.fronius.com | |
More detailed information on cabling Fronius DATCOM components can be found at: | |

Explanation of the multifunction current interface
Various wiring variants can be connected to the multifunction current interface. However, these cannot be operated simultaneously. For example, if an S0 meter is connected to the multifunction current interface, it is not possible to connect a signal contact for the surge protection device (or vice versa).
Pin 1 = measurement input: max. 20 mA, 100 Ohm measurement resistor (load impedance)
Pin 2 = max. short circuit current 15 mA, max. open circuit voltage 16 V DC or GND
Wiring diagram variant 1: Signal contact for surge protection device
Depending on the setting in the Basic menu (Signal Input submenu), the DC SPD option (surge protection device) either outputs a warning or an error on the display. Further information on the DC SPD option can be found in the Installation Instructions.
Wiring diagram variant 2: S0 meter
A meter for recording the self-consumption of each S0 can be connected directly to the inverter. This S0 meter can be positioned directly at the feed-in point or in the consumption branch. As one of the settings on the Fronius Datamanager website, a dynamic power reduction can be set under the "EVU Editor" menu item (see Fronius Datamanager 2.0 Operating Instructions on our website www.fronius.com)
IMPORTANT! In order to connect an S0 meter to the inverter, it may be necessary to update the inverter firmware.
Requirements for the S0 meter:
- Must comply with the IEC62053-31 Class B standard
- Max. voltage 15 V DC
- Max. current when ON 15 mA
- Min. current when ON 2 mA
- Max. current when OFF 0.15 mA
Recommended max. pulse rate of the S0 meter:
PV output kWp [kW] | Max. pulse rate per kWp |
30 | 1000 |
20 | 2000 |
10 | 5000 |
≤ 5.5 | 10,000 |
Description of the "Fronius Solar Net" LED
The "Fronius Solar Net" LED is on:
the power supply for data communication within the Fronius Solar Net / interface protocol is OK
The "Fronius Solar Net" LED flashes briefly every 5 seconds:
data communication error in the Fronius Solar Net
- Overcurrent (current flow > 3 A, e.g. resulting from a short circuit in the Fronius Solar Net ring)
- Undervoltage (not a short circuit, voltage in Fronius Solar Net < 6.5 V, e.g. if there are too many DATCOM components on the Fronius Solar Net and not enough electrical power is available)
In this case, power for the Fronius DATCOM components must be supplied by connecting an additional power supply (43,0001,1194) to one of the Fronius DATCOM components.
To detect the presence of an undervoltage, check some of the other Fronius DATCOM components for faults as required.
After cutting out because of overcurrent or undervoltage, the inverter attempts to restore the power supply in the Fronius Solar Net every 5 seconds while the fault is still present.
Once the fault is rectified, power to the Fronius Solar Net will be restored within 5 seconds.
Example
Recording and archiving data from the inverter and sensor using a Fronius Datamanager and a Fronius Sensor Box:
- Inverter 1 with Fronius Datamanager
- Inverters 2 and 3 without Fronius Datamanager!
 | = Terminating plug |
The external communication (Fronius Solar Net) takes place on the inverter via the data communication area. The data communication area contains two RS 422 interfaces as inputs and outputs. RJ45 plug connectors are used to make the connection.
IMPORTANT! Since the Fronius Datamanager functions as a data logger, the Fronius Solar Net ring must not include any other data logger.
Only one Fronius Datamanager per Fronius Solar Net ring!
Any other Fronius Datamanagers must be removed and the unoccupied option card compartment sealed off using the blanking cover (42,0405,2020 - available from Fronius as an optional extra); alternatively, use an inverter without Fronius Datamanager (light version).

Alarm function: | ||
ALL / Permanent: | Switching the floating switch contact for permanent and temporary service codes (e.g. brief interruption to energy being fed into the grid, a service code occurs a certain number of times a day - can be adjusted in the "BASIC" menu) | |
GAF | As soon as GAF mode is selected, the relay is switched on. The relay opens as soon as the power stage set registers an error and goes from normally feeding energy into the grid to being in an error state. This means that the relay can be used for fail-safe functions. Application example | |
Active output: | ||
ON: | The floating NO contact is on all the time the inverter is in operation (as long as the display is not dark or is displaying something). | |
OFF: | The floating NO contact is off. | |

Factory setting | 500 |
Setting range | 0 to the set switch-on point of the inverter (W or kW) |
Energy Manager
(under Relay menu item)
The "Energy Manager" (E-Manager) function can be used to activate the floating switch contact in such a way that it functions as an actuator.
Thus, a consumer that is connected to the floating switch contact can be controlled by specifying a switch-on or switch-off point that depends on the feed-in power (effective power).
The floating switch contact is automatically switched off:
- If the inverter is not feeding any power into the grid
- If the inverter is manually switched to Standby mode
- If the effective power is set to < 10% of the nominal output of the inverter.
To activate the Energy Manager function, select the "E-Manager" item and press the "Enter" key. | |
 | When the floating NO contact is off (open contact) |
 | When the floating NO contact is on (closed contact) |
To deactivate the Energy Manager function, select a different function (ALL / Permanent / OFF / ON) and press the "Enter" key.
NOTE!
Notes on setting up the switch-on and switch-off points
If the difference between the switch-on and switch-off points is too small, or if there are fluctuations in effective power, the result may be multiple switching cycles.
To avoid switching on and off frequently, the difference between the switch-on and switch-off points should be at least 100 - 200 W.
When choosing the switch-off point, the power consumption of the connected consumer should be taken into account.
When choosing the switch-on point, the weather conditions and anticipated insolation should be taken into account.
Application example
Switch-on point = 2000 W, switch-off point = 1800 W
If the inverter is outputting 2000 W or above, then the floating switch contact on the inverter is switched on.
If the inverter output falls to below 1800 W, the floating switch contact is switched off.
This allows useful applications, such as operating a heat pump or an air-conditioning system using as much self-generated power as possible, to be implemented quickly

Suitable USB flash drives
Due to the variety of USB flash drives available on the market, it cannot be guaranteed that every USB flash drive will be detected by the inverter.
Fronius recommends that only certified, industry-grade USB flash drives are used (look out for the USB-IF logo).
The inverter supports USB flash drives with the following file systems:
- FAT12
- FAT16
- FAT32
Fronius recommends that the USB flash drives employed should only be used for recording logging data or updating the inverter software. The USB flash drives should not contain any other data.
USB symbol on the inverter display, e.g. in display mode 'NOW': | ||
 |
| If the inverter detects a USB flash drive, the USB symbol will appear in the top right corner of the display. When inserting a USB flash drive, check whether the USB symbol is displayed (it may also flash). |
Note! Please note for outdoor applications that conventional USB flash drives are often only guaranteed to work within a restricted temperature range.
For outdoor applications ensure that the USB flash drive also functions, for example, at low temperatures.
USB stick for updating the inverter software
With the help of the USB stick, end customers can also update the inverter software via the USB item on the SETUP menu: the update file is first saved to the USB stick, from where it is then transferred to the inverter. The update file must be saved in the root directory on the USB stick.

Status diagnostics and troubleshooting
Status code display
The inverter performs a system self-diagnosis that automatically detects many faults that may occur and shows them on the display. This means you are promptly made aware of malfunctions in the inverter or the photovoltaic system, or of any installation or operating faults.
If the system self-diagnosis has detected a specific fault, the associated status code will be shown on the display.
IMPORTANT! Status codes may sometimes appear briefly as a result of the inverter's control response. If the inverter then continues working with no sign of any problem, this means that there was no fault.

Total failure of the display
- Check the AC voltage ON the inverter connections:
the AC voltage must be 230 V (+ 10 % / - 5 %)*.
| * | The mains voltage tolerance depends on the country setup |
Class 1 status codes
Class 1 status codes generally only arise momentarily and are caused by the public grid.
The initial response of the inverter in this case is to disconnect itself from the grid. The grid is subsequently checked for the stipulated monitoring period. If no further problem has been detected by the end of this period, then the inverter will resume feeding energy into the grid.
The GPIS SoftStart function is activated according to the country setup:
after cutting out due to an AC error, the output power of the inverter is continuously increased by 10% every minute in line with the VDE-AR-N 4105 guideline.
