Unit design:

(1)	Housing cover
(2)	Inverter
(3)	Mounting bracket
(4)	Connection area including 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 and synchronized with the mains voltage in use.

The inverter has been designed exclusively for use in grid-connected photovoltaic systems. It cannot generate electric power independently of the grid.

The inverter automatically monitors the public grid. Whenever conditions in the electric grid are inconsistent with standard conditions (e.g., grid switch-off, interruption), your inverter will immediately stop operating and interrupt the supply of power into the grid.
The grid is monitored by monitoring the voltage, monitoring the frequency and monitoring islanding conditions.

The inverter is fully automatic. The inverter starts monitoring the grid as soon as the solar modules are generating enough energy after sunrise. The inverter resumes the grid power feed operation when there is sufficient direct sunlight.
The control system of the inverter ensures that the maximum possible power output is drawn from the solar modules at all times.
As soon as there is no longer sufficient energy available for the grid power feed operation, the inverter shuts down the power electronics connection to the grid completely and stops operating. All settings and recorded data are saved.

When its temperature gets too high, the inverter automatically reduces the current output power in order to protect itself.
Reasons for the temperature being too high include a high ambient temperature or insufficient heat dissipation (e.g., inadequate heat dissipation when installed in switch cabinets).

1. General

The inverter is equipped with the following safety features as required by UL 1741 and the National Electrical Code:

Insulation monitor (IMI/RCMU)
The IMI (isolation monitor interruptor) feature is performed by the RCMU (residual current monitoring unit) feature in the inverter. This feature automatically monitors whether a leakage current exists in the grid power feed operation. The inverter is disconnected from the grid if a defined leakage current is exceeded.

Insulation monitoring of ungrounded solar modules
In the case of grid connected photovoltaic systems with ungrounded solar modules, the inverter checks the insulation resistance between the positive and negative pole in relation to the earth potential before energy is fed into the grid. The inverter issues a state code if the insulation resistance is too low. The inverter is therefore not permitted to start feeding energy into the grid.

1. General

The inverter is equipped with integrated arc detection/interruption, which detects and extinguishes serial arcs.

For example, a serial arc can occur after the following errors or situations:

• Poorly-connected plug connections on the solar module
• Poor or defective cable connections on the solar module side, which enable a connection against the earth potential
• Defective solar modules due to problems in the junction box or production errors, such as high resistance solder connections in individual solar cells
• Cables incorrectly connected to an inverter’s input terminals

If a serial arc is detected, the power is switched off and the grid power feed operation is interrupted. A state code is shown on the display. The state code on the display must be manually reset before the grid power feed operation can be resumed.

The power shutdown also extinguishes the serial arc.

1. General

The inverter is equipped with a Power Line Communication (PLC) transmitter on the DC side.
Its function is to ensure rapid shutdown in accordance with US safety standard NEC 2017 Art. 690.12. The PLC is implemented according to the specification "Communication Signal for Rapid Shutdown – SunSpec Interoperability Specification". Please visit www.sunspec.org for details.

• Keep the distance between the DC+ and DC- conductors as small as possible
• Avoid cable loops caused by cables that are too long (coil effect)
• Use metal cable ducts where possible
• Do not place DC cables from different inverters in the same cable duct or cable tray

1. General

There are warning notices and safety symbols on the inside and outside of the inverter. These warning notices and safety symbols must not be removed or painted over. They warn against incorrect operation, as this may result in serious injury and property damage.

		Safety symbols:
			Danger of serious injury and property damage due to incorrect operation
			Do not use the functions described here until you have fully read and understood the following documents: These Operating Instructions All Operating Instructions for the system components of the photovoltaic system, especially the safety rules
			Dangerous electrical voltage
			Wait for the capacitors to discharge.

Text of the warning notices:

WARNING!
Risk of electric shock!
Non-insulated inverter

Do not remove the cover. The device does not contain any user-serviceable parts. Maintenance work must be carried out by a trained service technician.
Both AC and DC voltage sources terminate inside this device. Each circuit must be turned off before carrying out maintenance work.
If the solar module is exposed to light, it will supply a DC voltage to the device.
Risk of electric shock due to energy stored in capacitors. Do not remove the cover until all power supply sources have been switched off for at least 5 minutes.
Ungrounded system: The DC cables in this PV system are not grounded and can be live.

1. General

Only valid for the device types with the "Ecofuse" option:

The use of string fuses provides additional fuse protection for solar modules.
The maximum short circuit current I_SC, the maximum module backfeed current I_R, and the specification of the maximum string fuse value in the module data sheet of the respective solar module are decisive factors in the protection of the solar module.

The maximum short circuit current I_SC per terminal is 15 A.

The string fuse release current can be set to greater than 15 A if required. However, a release current of 20 A must not be exceeded.

If the inverter is being operated with an external string collection box, the DC connector kit 25 (item numbers 42,0201,4479 for DC+ and 42,0201,4480 for DC-) must be used. In this case the solar modules are externally protected in the string collection box and the metal bolts should be used in the inverter.

National regulations regarding fuse protection must be observed. The electrical engineer carrying out the installation is responsible for the correct choice of string fuses.

The inverter is delivered with metal bolts as standard.

1. General

• I_N > 1.5 x I_SC
• V_N >/= maximum open circuit voltage of pv generator
• Fuse dimensions: Diameter 10 x 38 mm
  

1. Data Communication and Fronius Solar Net

Fronius developed Solar Net to make these system add-ons flexible and capable of being used in a wide variety of different applications. Fronius Solar Net is a data network that enables several inverters to be linked to the system add-ons.
Fronius Solar Net is a bus system with ring topology. Just one suitable cable is enough for communication between one or more inverters connected to Fronius Solar Net and a system add-on.
In order to clearly define each inverter in Fronius Solar Net, each inverter must also be assigned an individual number. You can assign individual numbers as per the "SETUP Menu" section.
Different system add-ons are automatically recognized by Fronius Solar Net.
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:
	→ http://www.fronius.com/QR-link/4204101938

1. Data Communication and Fronius Solar Net

Depending on the version, the inverter can be fitted with the Fronius Datamanager plug-in card (8).

1. Data Communication and Fronius Solar Net

Different switching variants can be connected to the multifunctional power interface. These variants cannot be operated at the same time, however. For example, if an S0 counter is connected to the multifunctional power interface, a signal contact for surge protection cannot be connected, and vice versa.

Pin 1 = measurement input: max. 20 mA, 100-ohm measurement resistor (apparent ohmic resistance)
Pin 2 = max. short circuit current 15 mA, max. open circuit voltage 16 V DC or GND

Switching Variant 1: Signal Contact for Surge Protection
The DC SPD (surge protection) option issues a warning or error on the display, depending on the setting in the basic menu (signal input submenu). More detailed information on the DC SPD option can be found in the Installation Instructions.

Switching Variant 2: S0 Counter
A counter for recording self-consumption per S0 can be connected directly to the inverter. This S0 counter can be placed at the feed-in point or in the consumption branch. A dynamic power reduction can be set under the DSO Editor menu subitem in the settings on the Fronius Datamanager website (see Fronius Datamanager 2.0 Operating Instructions on the homepage at www.fronius.com)

IMPORTANT! Connecting an S0 meter to the inverter may require an inverter firmware update.

Requirements for the S0 meter:

• Must meet standard IEC 62053-31 Class B
• 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. impulse rate of S0 meter:

1. Data Communication and Fronius Solar Net

The ‘Fronius Solar Net‘ LED is illuminated:
Power supply for the data communication within the Fronius Solar Net/interface protocol is OK

The ‘Fronius Solar Net‘ LED flashes briefly every 5 seconds:
Error in the data communication in the Fronius Solar Net

• Overcurrent (current flow > 3 A, e.g. due to a short circuit in Fronius Solar Net ring)
• Undervoltage (no short circuit, voltage in Fronius Solar Net < 6.5 V, e.g. if too many DATCOM components are in Fronius Solar Net and the electrical supply is insufficient)
  
  In this case, an additional power supply is required for the Fronius DATCOM components using an external power supply (43,0001,1194) on one of the Fronius DATCOM components.
  
  Check other DATCOM components to detect any undervoltage present.

After a shutdown due to overcurrent or undervoltage, the inverter tries to restore the energy supply in the Fronius Solar Net every 5 seconds so long as there is an error.

Once the error has been corrected, power is restored to Fronius Solar Net within 5 seconds.

1. Data Communication and Fronius Solar Net

Logging and archiving inverter and sensor data using a Fronius Datamanager and Fronius Sensor Box:

Data network with three inverters and one Fronius Sensor Box:
- inverter 1 with Fronius Datamanager
- inverter 2 and 3 without Fronius Datamanager.

= termination plug

External communication (Fronius Solar Net) takes place in the inverter via the data communication area. The data communication area has two RS-422 interfaces: an input and an output. RJ45 plug connectors are used to establish the connection.

IMPORTANT! Only one Fronius Datamanager in primary operation is permitted per Fronius Solar Net Ring. Switch other Fronius Datamanagers to secondary operation or remove them (see chapter "Controls, connections, and indicators on the Fronius Datamanager 2.0").
Unused option card slots can be closed by replacing the cover (item number - 42,0405,2094), or an inverter without Fronius Datamanager (light version) can be used.

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. Menu Items in the Setup Menu

A floating switch contact (relay) on the inverter can be used to display status codes, the inverter status (e.g. the grid power feed operation) or the Energy Manager functions.

* is only shown if the “E-Manager” function has been activated under “Relay Mode.”

1. Menu Items in the Setup Menu

The "Energy Manager" function can be used to control the floating switch contact so that this acts as an actuator.
A load connected to the floating switch contact can therefore be controlled by assigning a switch-on or switch-off point depending on the feed-in power (effective power).

• When no current is being fed into the public grid by the inverter
• When the inverter is manually switched to standby mode
• When there is an effective power assignment < 10% of the inverter's rated power output

To activate the Energy Manager function, select "E-Manager" and press the "Enter" key.
When the "Energy Manager" function is activated, the "Energy Manager" icon is shown at the top left of the display:

   when the floating NO switch contact is switched off (open contact)

   when the floating NC switch contact is switched on (closed contact)

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

When selecting the switch-off point, consider the power consumption of the connected load.

When selecting the switch-on point, consider the weather conditions and the expected solar radiation.

Application example
Switch-on point = 2,000 W, switch off point = 1,800 W

If the inverter supplies 2,000 W or more, the inverter's floating switch contact is switched on.
If the inverter output falls below 1,800 W, the floating switch contact is switched off.

This makes it possible to quickly implement interesting application options, such as operating a heat pump or an air-conditioning system using as much self-produced power as possible

Your inverter is equipped with system self diagnosis that automatically identifies a large number of possible operation issues by itself and displays them on the screen. This enables you to know immediately if there are any malfunctions in the inverter or the photovoltaic system or any installation or operating errors.

Whenever the system self diagnosis has identified a particular issue, the respective status code is shown on the screen.

IMPORTANT! Status codes may sometimes appear briefly as a result of the control response from the inverter. If it subsequently continues to operate normally, there has not been a system error.

1. Status Diagnosis and Troubleshooting

• Check the AC voltage at the inverter's connections:
  the AC voltage must be 208/220/240/440/480 V (+10%/-12%) depending on the grid.

1. Status Diagnosis and Troubleshooting

Status codes in class 1 are typically temporary. Their cause lies in the grid.

Example: The grid frequency is too high and the inverter is not permitted to feed energy into the grid because this would not comply with a standard. No device fault has occurred.
The inverter will first respond by disconnecting from the grid. Then, the grid will be checked for the duration of the observation period stipulated. If, after the end of this period, no further defect is identified, your inverter resumes operating and feeding energy into the grid.

The GPIS soft start function is activated depending on the country setup:
According to national guidelines, the output power of the inverter increases continuously after a shutdown due to an AC error.
