1. Safety rules

The inverter generates a maximum sound power level of < 65 dB(A) (ref. 1 pW) when operating under full load in accordance with IEC 62109-1:2010.

The device is cooled as quietly as possible with the aid of an electronic temperature control system, and 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.

1. Safety rules

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 equipment that is susceptible to interference 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 action to rectify the situation.

1. Safety rules

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.

(3)	Mounting bracket
(4)	Connection area incl. DC main switch
(5)	Data communication area
(6)	Data communication cover

The inverter transforms the direct current generated by 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, frequency and 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).

1. General

• Any use above and beyond this purpose
• Making any modifications to the inverter that have not been expressly approved by Fronius
• the installation of components that are not distributed or expressly approved by Fronius.

Fronius shall not be liable for any damage resulting from such action.
No warranty claims will be entertained.

• Carefully reading and obeying all the instructions and all the safety and danger notices in the Operating Instructions and Installation Instructions
• Performing all stipulated maintenance work
• Installation as specified in the Installation Instructions

When designing the photovoltaic system, ensure that all components are operated within their permitted operating ranges at all times.

Observe all the measures recommended by the solar module manufacturer to ensure that the solar module retains its properties in the long term.

Obey the regulations of the power supply company regarding connection methods and energy fed into the grid.

1. General

1. Data communication and Fronius Solar Net

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. For instructions on how to assign a unique number, refer to the section SETUP menu item.

Fronius Solar Net automatically recognises a wide variety of system add-ons.

In order to distinguish between several identical system extensions, each one of them 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 ® http://www.fronius.com/QR-link/4204101938

1. Data communication and Fronius Solar Net

Depending on the model, the inverter may be equipped with the Fronius Datamanager plug-in card (8).

1. Data communication and Fronius Solar Net

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 protective device
Depending on the setting in the Basic menu (Signal Input submenu), the DC SPD option (surge protective 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.

IMPORTANT! In order to connect an S0 meter to the inverter, it may be necessary to update the inverter firmware.

The S0 meter must comply with the IEC62053-31 Class B standard

1. Data communication and Fronius Solar Net

In the Fronius Solar Net ring (a combination of several inverters), the Fail-Safe function prevents inadmissible feeding of the connected inverters in the start-up phase or during operation. For this purpose, a signal is transmitted from the primary inverter with built-in data manager to the secondary inverters (Lite devices).

The function is activated as soon as the data manager fails or the Solar Net connection is interrupted. In this case, the signal is not transmitted to the secondary inverters. All devices switch off with status 710.

The following requirements must be met to enable the Fail-Safe to function correctly:

• For all inverters in the Solar Net ring, Fail-Safe Mode must be set to Permanent and Fail-Safe Behaviour to Disconnect.
• The inverter with data manager must be located in the last position of the ring line.

Correct wiring

Function in the event of a fault

Faults occur at the beginning and end of the Solar Net ring – the primary inverter stops sending the signal, and secondary inverters switch off with status 710.

Faults occur at the beginning and end of the Solar Net ring or between the connected inverters – the primary inverter stops sending the signal, and secondary inverters switch off with status 710.

1. Data communication and Fronius Solar Net

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.

Recording and archiving data from the inverter and sensor using a Fronius Datamanager and a Fronius Sensor Box:

Data network with 3 inverters 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).

Energy companies or grid operators may impose feed-in limits on an inverter. Dynamic power reduction takes account of self-consumption by the household before the power of an inverter is reduced:

A counter for determining self-consumption of the S0 can be connected directly to the inverter – see chapter Explanation of the multifunction current interface on page (→)

A feed-in limit can be set in the Basic menu under Signal input – S0 meter – see chapter Menu items in the Basic menu on page (→).

• Grid feed-in limit
  Field for entering the maximum grid feed-in power in W. If this value is exceeded, the inverter regulates down to the set value within the time required by national standards and regulations.
• Pulses per kWh
  Field for entering the pulses per kWh of the S0 meter.

Zero feed-in is possible with this configuration.

When using the S0 meter and power reduction by means of an inverter, the S0 meter must be installed in the consumption branch.

S0 meter in the consumption branch

If dynamic power reduction is subsequently configured using the Fronius Datamanager 2.0 (Inverter user interface - UC Editor menu - Dynamic power reduction), dynamic power reduction must be deactivated using the inverter (Inverter display - Basic menu - Signal input - S0 meter).

The inverter is fitted with the WLAN-enabled system monitoring Fronius Datamanager 2.0 as standard.
The following functions are included with the system monitoring:

• Dedicated web page displaying current data and a wide range of settings
• Ability to connect to Fronius Solar.web using WLAN or LAN
• Automatic sending of service messages by SMS or e-mail in the event of a fault
• Option of controlling the inverter by specifying power limit values, minimum or maximum running times or target running times
• Control of the inverter via Modbus (TCP / RTU)
• Ability to assign control priorities
• Ability to control the inverter by means of connected meters (Fronius Smart Meter)
• Ability to control the inverter via a ripple control signal receiver (e.g. by specifying the reactive power or effective power)
• Dynamic power reduction, taking self-consumption into account

1. The Setup menu items

Status codes (state codes), the status of the inverter (e.g. feeding energy into the grid) or Energy Manager functions can be displayed using the floating switch contact (relay).

* these are only shown if the "E-Manager" function has been activated under "Relay mode".

1. The Setup menu items

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).

• 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 "Energy Manager" function is running, the "Energy Manager" symbol will appear in the top left corner of the display:

   When the floating NO contact is off (open contact)

   When the floating NC contact is on (closed contact)

To deactivate the Energy Manager function, select a different function (ALL / Permanent / OFF / ON) and press the "Enter" key.

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

1. USB Stick as a Data Logger and for Updating Inverter Software

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 drive 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).

IMPORTANT! 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.

To start up the inverter again, follow the steps listed above in reverse order.

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.

1. Status diagnostics and troubleshooting

• Check the AC voltage ON the inverter connections:
  the AC voltage must be 230 V (+ 10 % / - 5 %)*.
  

1. Status diagnostics and troubleshooting

Class 1 status codes generally only arise momentarily and are caused by the public grid.

Example: The grid frequency is too high and the inverter may not feed any energy into the grid owing to a standard. There is nothing wrong with the device.
The initial response of the inverter is to disconnect itself from the grid. The grid is subsequently checked during 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 in line with the national guidelines.

1. Status diagnostics and troubleshooting

Class 3 includes status codes that may occur while feeding energy into the grid, but generally do not cause the process to be interrupted for any length of time.

The inverter disconnects automatically from the grid, the grid is then monitored as specified and the inverter attempts to resume feeding energy into the grid.

1. Status diagnostics and troubleshooting

Some of the class 4 status codes necessitate intervention by a Fronius-trained service technician.

1. Status diagnostics and troubleshooting

Class 5 status codes do not generally interfere with feeding energy into the grid, but can cause restrictions. These status codes are displayed until they are acknowledged by pressing a key (however, the inverter continues to operate normally in the background).

1. Status diagnostics and troubleshooting

Class 7 status codes relate to the control system, the configuration and inverter data recording, and may directly or indirectly affect the process of feeding energy into the grid.

1. Status diagnostics and troubleshooting

• an error appears frequently or all the time
• an error appears that is not listed in the tables

1. Status diagnostics and troubleshooting

When operating the inverter in extremely dusty environments:
when necessary, clean the cooling elements and fan on the back of the inverter as well as the air intakes at the mounting bracket using clean compressed air.
