Safety Precauti­ons at the Machi­ne Location
Ensure when installing machines with cooling-air vents that the cooling air can flow freely through the air vents without obstruction. Only operate the machine with the degree of protection specified on the rating plate.
Mains connection
High-performance devices (> 16 A) can affect the voltage quality on the mains network because they can feed powerful current into the main supply. This may affect a number of types of device in terms of:
- connection restrictions
- criteria with regard to maximum permissible mains impedance
*)
- criteria with regard to minimum short-circuit power requirement
*)
*)
at the interface with the public mains network
see Technical Data
In this case, the plant operator or the person using the device should check whether or not the device is allowed to be connected, where appropriate through discussion with the power supply company.
EMC device classifications
Devices with emission class A:
- are only designed for use in an industrial setting
- can cause conducted and emitted interference in other areas.
Devices with emission class B:
- satisfy the emissions criteria for residential and industrial areas. This also applies to residential areas in which power is supplied from the public low-voltage grid.
EMC device classification as per the rating plate or technical specifications
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.
Information on noise emission values
The inverter generates a maximum sound power level of <80 dB(A) (ref. 1pW) when operating under full load in accordance with IEC 62109-1.
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.

IMPORTANT SAFETY INSTRUC­TIONS - SAVE THESE INSTRUC­TIONS
Housing
This manual contains important instructions for the FRONIUS IG 2000, 3000, 2500-LV, 4000, 5100, 4500-LV that shall be followed during installation and maintenance of the inverters.
General
WARNING! These servicing instructions are for use by qualified
personnel only. To reduce the risk of electric shock, do not perform any servicing other than that specified in the operating instructions unless you are qualified to do so.
Electrical installations must be made in accordance with the National Electrical Code, ANSI/NFPA 70, and any other codes and regulations applicable to the installation site.
To reduce the risk of fire, do not connect multiwire branch circuits to an AC load center (circuit breaker panel).
WARNING! Incorrect operation and work performed incorrectly can cause serious injury & damage! Only qualified staff are authorized to install your FRONIUS IG and only within the sco­pe of the respective technical regulations. Do not start operati­on or carry out maintenance work before you have read the chapter “Safety Regulations“!
5
Only FRONIUS service staff are authorized to carry out repairs to the FRONIUS IG unit.
Repair
The design and function of the FRONIUS IG unit offers a maximum level of safety, both during installation as well as in operation. A com­plete galvanic isolation between the DC and AC sides is one such safety feature.
The FRONIUS IG provides galvanic isolation and grid monitoring. The passive and active measures for the protection of persons and equipment help ensure safe installation and operation.
Galvanic isolation
Whenever conditions in the electric grid are inconsistent with stan­dard conditions (for example grid switch-off, interruption, etc.), your FRONIUS IG unit will immediately stop operating and interrupt the supply of power into the grid.
Your FRONIUS IG unit determines the grid’s status by:
- monitoring voltage
- monitoring frequency
- monitoring islanding conditions
This scheme prevents dangerous voltages at the AC lines and con­stitutes an essential contribution towards avoiding hazards for the maintenance staff.
Monitoring the grid
Before connecting the solar modules, you must check whether the voltage parameters specified in the manufacturer’s data correspond with the actual parameters.
When checking the voltage reading, please take into account that solar modules supply a higher open circuit voltage when temperatu­res are low and sunlight level remains unchanged.
The data sheet of the solar module will tell you the temperature fac­tors applicable for ascertaining the theoretical open-circuit voltage at 14 °F (-10 °C).
If the solar modules exceed an open-circuit voltage of 500 V, regard­less of temperature the FRONIUS IG unit might be damaged and all warranty rights will be voided.
Solar modu­les
6
Your FRONIUS IG unit complies with the requirements for "Inverters, converters and controllers for use in independent power systems" UL1741-2005 and IEEE 1547 standards. The ground-fault detection and interruption is in compliance with NEC 690 building code re­quirements.
The respective conformity declarations can be found in the appendix to these operating instructions.
Only appropriately licensed contractors are authorized to connect your FRONIUS IG to the grid. Consult your local authorities for speci­fic requirements.
Before connecting the FRONIUS IG to the grid, permission for the connection must be granted by the utility company.
Grid connec­tion
Standards and Regulati­ons
Product lis­tings and compliance
The FRONIUS IG includes a ground fault detector interruptor (GFDI) according to UL 1741. This device measures the ground current of the PV array and prevents the inverter from feeding the grid in case of a ground fault.

The direct current generated in the solar modules can only be fed into the grid or used in your home after having been transformed by an inverter. This is the basic purpose of your FRONIUS IG unit.
Electricity is converted under the roof
In a parallel connection of several such strings the output power and the output current will increase, while the voltage will remain unchan­ged (see right picture). The combination of all solar modules con­nected in series and parallel is called a solar array.

The energy from worldwide sunlight amounts to a total of about 1,540,000,000,000,000,000 kWh/year (1,540 Peta kWh/year). This is 15,000 times as much as the electricity consumption worldwide. We congratulate you on your decision to actively use world’s biggest energy resource. The word "photovoltaic" comes from the driving force behind this technology, which is light. When light strikes photo­voltaic cells, a voltage and current is created.
General infor­mation
How a photovoltaic system works
Power output and voltage are increased by combining a number of solar cells. If solar modules are connected in series like on a string, both the output power as well as the voltage will increase.

The FRONIUS IG is the latest generation of solar inverter. It is the highly complex link between solar modules and the grid.
As such it is responsible for a number of high-level tasks. The follo­wing diagram gives a graphical overview as to where the FRONIUS IG is placed in the PV system.

Operation manual
The FRONIUS IG unit transforms the direct current generated by the solar modules into alternating current. This alternating current is fed into your home system or into the public grid and synchronized with the voltage that is used there. The FRONIUS IG has been designed exclusively for use in grid connected photovoltaic systems. It cannot generate electric power independent from the grid.
Converting DC into AC current
9
The FRONIUS IG has been designed for use with solar modules of a wide range of input voltages. This allows the use of the greatest variety of types of solar modules. Important notice: the parameters indicated for maximum DC voltage (total voltage of the solar modules connected) must at no time be exceeded!
By its design and operation, the FRONIUS IG offers maximum safety during installation as well as in operation.
The FRONIUS IG is equipped with an HF-transformer (HF = high frequency) that ensures galvanic isolation between the DC side and the grid. In addition, the HF principle results in a drastic reduction of the transformer’s size, which means that it requires less space and has considerably less weight. The FRONIUS IG unit achieves a high degree of efficiency due to its innovative circuit schemes.
Voltage trans­formation and galvanic isolation
The FRONIUS IG unit monitors the grid. This responsibility compri­ses all measures necessary for the protection of persons and machi­nes in case of a power blackout or other grid loss.
The FRONIUS IG unit is programmed to stop operation immediately and stop supplying power whenever conditions in the grid deviate from standard conditions (for example, when power is switched off or in case of any other kind of interruption).
The FRONIUS IG is fully automatic. Starting at sunrise, as soon as the solar modules generate enough power, the automatic control unit starts monitoring voltage and frequency. As soon as there is a suffi­cient level of insolation, your solar inverter starts feeding energy to the grid. A few Watts of solar power output are sufficient to achieve this.
The control system of the FRONIUS IG unit ensures that the maxi­mum possible power output is drawn from the solar modules at all times.
This function is called MPPT (Maximum Power Point Tracking). It operates with extremely high precision. As dusk starts and there is no longer sufficient energy available to feed power into the grid, the FRONIUS IG unit shuts down the grid connection completely and stops operating. All settings and data recorded are saved.
Fully automa­tic operation management
Monitoring the grid
10
The FRONIUS IG unit comes standard with a display that has been designed to enable quick and easy access to the most important data in your PV system.
The FRONIUS IG is equipped with a basic logging function to moni­tor minimum and maximum data on a daily and a cumulative basis. There is also an option to allow the reading of the following weather data on the display:
- two different temperature readings (for example, temperature at the solar modules as well as the outside temperature)
- irradiance
In addition to the functions installed in the FRONIUS IG unit, a wide choice of data communication products allows for many possibilities of recording and visualizing data. The respective components requi­red to upgrade the system are easy to install.
With each additional parameter, that is controlled directly by the inverter, installation becomes easier and less costly because no additional peripheral equipment will be required. Based on our expe­rience and the use of the most innovative technologies, the FRONI­US IG unit is able to manage all system parameters simultaneously.
In addition, the FRONIUS IG unit complies with a wide range of requirements established for the safety of people and other house­hold appliances, as well for its own protection.
Some of these requirements are:
- ability to monitor the grid
- the quality of the electricity supplied
- immunity from outside disturbance and interference (for example, from mobile telephones).
Your advan­tage
There are several ways the FRONIUS IG unit can identify a grid­cutoff, by monitoring:
- voltage
- frequency
- islanding conditions

Product description
The FRONIUS IG Unit
The FRONIUS IG unit is designed for fully automatic operation. No manual control is necessary for feeding the power it generates into the grid.
The FRONIUS IG unit starts operating automatically as soon as the power output of the solar modules is sufficient after sunrise.
During its operation the FRONIUS IG unit optimizes the voltage of the solar modules for maximum power output.
- the optimal voltage for any particular solar module is called MPP voltage (MPP = maximum power point)
- maintaining the exact MPP voltage guarantees an optimal level of efficiency for your modules at any time (MPP-tracking).
As soon as dusk begins there is no longer sufficient energy available to feed into the grid. The FRONIUS IG unit fully shuts off the grid connection at this time.
- during the night the FRONIUS IG unit draws less than 150 mW from the grid
- the data and parameters are saved
- it is also possible to shut the unit off manually
How it func­tions
After switching on automatically, the FRONIUS IG unit goes through a self-test, followed by an extensive test of the grid. This test takes five minutes. During the startup sequence the LED illumination is yellow.

For unlimited system upgradeability, Fronius has developed the LocalNet. LocalNet is a data network that allows linking multiple FRONIUS IG units with data communication components.
LocalNet is a bus system. One single cable is sufficient to allow communication between one or several FRONIUS IG units with all system upgrade elements. This reduces the cable requirement to a minimum.
Upgrading the system
Other system upgrades are offered in external housings
Additional information
The FRONIUS IG unit is prepared for a whole series of system up­grades, such as:
- Communication between FRONIUS IG and DatCom units
- Dataloggers (for recording and managing your photovoltaic system data via personal computer), including Datalogger and modem connection
- Interface Card Easy sends all relevant working parameters in a well defined RS-232 protocol
- Personal Display FRONIUS IG
- Various large displays (FRONIUS IG Public Display)
- Sensors (temperature sensor / irradiance / electricity consumption meter / ...)
For more information on Fronius communication products, please refer to the individual product literature, www.fronius-usa.com.
Some system upgrades are offered as plug-in cards, similar to those on your personal computer.
40
The FRONIUS IG unit is equipped with a temperature controlled, variable speed fan that provides the following features:
- more compact housing - as a result of smaller heat sinks
- components are better cooled - efficiency increases / longer life
- least possible energy consumption / noise level, due to the variable speed control and ball bearing support
- should there be insufficient heat dissipation in spite of the fan ope­rating at maximum speed (for example inadequate heat transfer away from the heat sinks) the power will be derated for protection of the FRONIUS IG unit.
- derating the power reduces the output of the FRONIUS IG unit for a short period sufficient to ensure that the temperature will not exceed the admissible limit.
- your FRONIUS IG unit will remain ready for operation as long as possible without any interruption.

Installation
Safety
WARNING! Work performed incorrectly can cause serious injury
and damage.
- Read the installation instructions carefully before installing the FRONIUS IG.
- Only a qualified electrical professional is authorized to carry out the installation of the FRONIUS IG.
These installation instructions serve as a manual for qualified electrical professionals and detail the installation, initial operation, status diagnosis and repair processes. It is in your interest to read the operating instruc­tions thoroughly and follow the instructions it contains. In so doing you will avoid malfunctions resulting from incorrect operation.
Installation instructions
General infor­mation
Your FRONIUS IG is the latest generation of solar inverter. It is the highly complex link between your solar modules and the grid. As such, it is in charge of a number of highly technical tasks. The following diagram should give you a brief overview of a PV system including a FRONIUS IG.
Main AC Load Center
Energy­meter
FRONIUS IG
PV-array
43
To get the most out of your FRONUS IG unit, observe the following rules:
- Limit grid impedance by using an appropriately-sized AC conductor between the FRONIUS IG unit and the in-house distribution panel. The AC conductor cable resistance between the FRONIUS IG unit and the house distribution panel should not exceed 0.5 Ohm. This can be achie­ved by using the following cable-sizes (according to NEC handbook, chapter 9, table 8):
- AWG 10: maximum 200 ft. (60 m)
- AWG 12: maximum 126 ft. (38 m)
- Only install it on a solid vertical wall at a minimum of 3 ft. (0.9 m) above the ground and to a maximum of 6.5 ft. (2 m)
- The ambient temperature should not be below -4 °F (-20 °C) or over 122 °F (50 °C).
- No objects are to be located within a distance of 6 in. around the air vents on both sides of the FRONIUS IG unit.
- Keep a distance of 8 in. minimum. For optimal airflow and cooling effi­ciency in hot climates Fronius recommends a distance of 10 - 12 in. between each inverter or anything to the right or left of the inverter such as walls or DC and AC disconnects.
- The air flow direction within the inverter is from left to right (cold air intake on left, hot air exit on right).
- When installing the FRONIUS IG unit in a switch panel cabinet (or similar closed environment) it is necessary to make sure that the hot air that develops will be discharged by forced ventilation.
Choosing the location gene­ral
- during certain operation phases the FRONIUS IG unit may produce a slight noise. For this reason it should not be installed in an occupied living area
- the FRONIUS IG unit is not to be set up in areas with large amounts of dust. If unavoidable, place the FRONIUS IG in an appropriately rated and ventilated box.
- the FRONIUS IG unit is not to be set up in areas with large amount of conducting dust particles (for example iron filings)
- the FRONIUS IG unit is to be installed at a height that keeps the display slightly below eye level for best possible readability of the display.
- NEMA 3R protection means that the FRONIUS IG can be exposed to moisture. However, we recommend that direct moisture be avoided, if possible.
- In spite of the NEMA 3R protection system, the FRONIUS IG should not be exposed to direct sunlight, as this could result in temperature dera­ting.
Choosing the location
44
Preparing the wall mounting
The following describes how the FRONIUS IG is mounted to the wall. As your FRONIUS IG is delivered, the mounting plate is fixed to the inverter by two screws on the bottom of the FRONIUS IG.
For mounting the inverter to the wall proceed as follows:
- Loosen the screws (1) on the bottom of the inverter and remove the mounting plate (2)
- Fix the mounting plate (2) to the wall using four suitable screw anchors (3) and screws (4)
In most cases, you should use 1/4 in. or 5/16 in. stainless steel or alumini­um screws capable of supporting 26 lbs (FRONIUS IG 2000, 3000 and 2500-LV) or 42 lbs (FRONIUS IG 4000, 5100 and 4500-LV) of inverter weight. Triangulate the positions of these on the mounting plate using the pre-drilled holes when possible. Three vertically aligned holes for single stud mounting will suit most installations.
CAUTION! The FRONIUS IG may become dislodged and fall from the mounting plate if the unit is not fixed to the mounting plate using the two screws at the bottom (that were removed at the beginning).
Important! Due to the variety of screw anchors (3) and screws (4) available for the various types of wall surfaces, these are not inclu­ded.
NOTE! If you modify the FRONIUS IG enclosure with custom openings you will be required to return the unit for repair in the event of a warranty-related issue rather than doing an inverter exchange. Knockouts for grounding electrode may be required by local authorities.
- Slide the FRONIUS IG from above so that the unit may hang from the top of the mounting plate (2)
- Attach the FRONIUS IG to the bottom of the mounting plate (2) by using the screws (1) that were removed before

When selecting your solar modules to use with the FRONIUS IG unit, keep in mind this critical point: The open circuit voltage increases when temperature decreases (assuming constant irradiance). Therefore, at 14 °F (-10 °C) the open-circuit voltage must not exceed 500 V.
- Whenever the open-circuit voltage of the solar modules exceeds 500 V, the FRONIUS IG unit may be damaged, and all warranty rights will become null and void.
- More exact data for sizing the solar array for the particular location can be obtained using calculation tools such as the FRONIUS IG System Configuration Tool (available on www.fronius-usa.com).

Your FRONIUS IG unit needs to be connected to the DC/AC Disconnect Switches and to the equipment grounding according to the enclosed diagrams.
Your FRONIUS IG is equipped with a PV and Utility disconnect switch that switches AC and DC separately.
Depending on the installation, an external AC and/or DC disconnect may be required if the inverter is installed in a location not easily accessible to utility or fire personnel. Consult local authorities for additional information.
WARNING! In order to ensure the best possible operation of the grid monitoring system, it is important to make sure that there is minimal resistance in the lines to the connection point. The AC conductor resistance between the FRONIUS IG unit and the building’s distribu­tion panel should not exceed 0.5 Ohm.
The FRONIUS IG comes from the factory pre-configured for grid connec­tion with neutral. The FRONIUS IG may be reconfigured for grids without neutral by setting the jumper on the PC-board as shown in the figure.
NOTE! The neutral conductor is not bonded to ground internally.
Important! Open the connection area as explained in the section „Con-
nection“.

NOTE! To access the DC terminals, the white plastic divider needs
to be bent upward or rotated out of the way.
- Insert the DC cables through the DC conduit and connect them to the terminal block.
- Connect the positive (+) cables to the "DC+" terminals, and the negative (-) cables to the "DC-" terminals and tighten them with a torque of 1.7 ft. lbf.
NOTE! It is possible to connect up to 3 PV-strings in parallel within the FRONIUS IG 2000, 3000, 2500-LV, 4000, 5100 and 4500-LV.
NOTE! Do not connect the ground to the DC negative at any point! This is already done within the FRONIUS IG. If the DC negative is connected to ground at the DC terminal block or prior, this will circumvent the GFDI protection system, preventing your FRONIUS IG from properly detecting a fault current. Additionally, turning the DC disconnect to the off/open-circuit condition will not disconnect the array from ground, as it only disconnects the DC positive.
- Connect the module frame ground wire to the second terminal (6) la­beled .
Important! Use minimum AWG 10, min. 167 °F (75 °C), copper wire for all grounding cables.
- Tighten wires with a torque of 1.7 ft. lbf.
- For your convenience, an additional grounding electrode terminal (7) is provided in case local regulations require additional grounding measu­res.
NOTE! Connecting the DC wiring with the wrong polari­ty may cause damage to the inverter. Connect the DC cables as described in the following instructions.
Check both the polarity and the open circuit voltage. The DC Volta­ge must not exceed 500 V, regard­less of temperature.

Start up Operation
Configuring your Inverter
Your FRONIUS IG unit has been pre-configured in the factory and is ready for operation.
After mounting the FRONIUS IG unit to the wall and connecting it to the solar modules (DC) and to the grid (AC), all you have to do is turn on the AC and DC circuit disconnects.
Factory pre­set configura­tion
LED
- as soon as the photovoltaic modules produce sufficient power, the status LED lights up orange and the screen displays the startup proce­dure
- the orange LED indicates that the feed-in mode of the FRONIUS IG will begin shortly
- after the FRONIUS IG unit has started feeding the energy into the grid, the LED light turns green
- the LED light continues green as long as power is fed into the grid. This confirms that the FRONIUS IG is operating properly and feeding energy into the grid.
55
The FRONIUS IG is equipped with a ground-fault detection and interrupti­on (GFDI) circuit as required by UL 1741 and the National Electrical code. The array’s negative conductor is connected to the grounding system in the inverter. If a ground fault occurs in the DC cabling, the inverter discon­nects from the grid. The fault is indicated by the red ground-fault LED and the service code "434" is shown on the display. In this situation, the FRO­NIUS IG is blocked from reconnection to the grid until the following ac­tions are taken:
- Turn the AC and DC disconnect to position OFF (open-circuit)
- Remove the ground fault in your photovoltaic system
- Test the GFDI fuse and replace if necessary
NOTE! When a defective fuse is changed, only replace it with a "Littlefuse KLKD 1 AMP 600V" fuse.
- Turn the AC and DC disconnect to position ON (closed circuit)
To change your inverter settings, please consult the chapter entitled "Ope­rating Scheme", in the "Setup Menu" section of your operating instruc­tions.
In case the initial operation of your FRONIUS IG unit does not proceed as shown above and the FRONIUS IG unit does not start feeding power into the grid, consult the chapter "Error Diagnosis and Repair".

LocalNet automatically identifies different system upgrades (Datalogger Box, Sensor Box, ...). However it is not able to differentiate between seve­ral identical system upgrades.
In order to define each FRONIUS IG unit in the LocalNet, the respective unit must have its own individual identification number. For the respective procedure to assign these identification numbers, please consult the chapter "Setup Menu" in your operating instructions.
NOTE! Each FRONIUS IG that is to supply data must be equipped with a COM Card.
The Datalogger Box has one USB interface for connection to a personal computer and one RS-232 interface for connection to a modem. The Datalogger Card has two RS-232 interfaces for connection to a personal computer and to a modem.
NOTE! The order of sequence for placing the sensor boxes, data­logger box, and inverters does not matter. However:
- Each FRONIUS IG can have only one COM Card
- Each network can contain only one Datalogger Card or box.
- Each network can contain up to 10 Sensor Cards or boxes.
More information on the various system upgrade possibilities can be found in the respective service manuals or on the internet at www.fronius-usa.com.

Status diagnosis and repair
Service-Codes Displayed
Your FRONIUS IG unit is equipped with a self diagnostic system that automatically identifies a large number of possible operation issues by itself and displays them on the screen. Therefore it is possible to quickly isolate technical issues, and to distinguish between Service Codes related to the installation versus Service Codes which are internal to the inverter.
Whenever the self diagnostic system has identified a particular issue, the respective service code is displayed on the screen.
NOTE! Display of a service code for a short time may be the result of the control procedures of your FRONIUS IG unit. If it subse­quently continues to operate normally, there has not been a sys­tem error.
Service dis­play
After a short time the FRONIUS IG resumes grid synchronization (messa­ge: "SYNCAC").
As soon as the open-circuit voltage exceeds 150 V, the FRONIUS IG unit starts synchronizing with the grid (display shows "SYNCAC").
If the total power output of the solar modules is insufficient, the display shows the message "POWER
LOW
."
Normal opera­tion service codes
As long as the open-circuit voltage of the solar modules is not sufficient, the screen displays the information "DC
LOW
."
60
Should the display remain dark for a longer period of time after sunrise, check the open circuit voltage of the solar modules.
Should the open circuit voltage of the modules (at the terminals within the FRONIUS IG) not reach 170 V, it is possible that there is a problem on the DC side of the photovoltaic system (e.g. wrong module configuration).
If the open circuit voltage of the solar modules (at the terminals of the FRONIUS IG unit) amounts to more than 170 V, there may be an issue with the FRONIUS IG unit. In this case, consult a Fronius trained service technician.

Policy and procedure for warranty re­turns and repairs
At Fronius, we have been designing and manufacturing high quality power electronics equipment for over 60 years. And all our production facilities are ISO 9001 certified.
You will probably not encounter any service-related issues with your FRO­NIUS IG Solar Inverter. However, in the unlikely event that within Ten (10) years from the original purchase you discover a problem caused by de­fects in either workmanship or materials, we will see that it is either re­paired or replaced. Repair or replacement depends on Fronius’ evaluation of the issue and what we decide makes the most sense according to the situation. The warranty is based on the inverter’s serial number, allowing the warranty to be transferred to another owner if the FRONIUS IG Solar Inverter remains installed in the original installation location. Because the warranty is tied to the serial number, there is no paperwork to transfer the warranty to a new owner.
The FRONIUS IG Solar Inverters are designed to withstand normal opera­ting conditions and typical wear and tear when the FRONIUS IG Solar Inverter is used for its original intent, in compliance with the FRONIUS IG Installation and Operational Manual(s) supplied with the original equip­ment. This warranty does not cover damages by improper installation or operation, misuse, abuse, manipulation, alterations or repair attempts, accidents, fire, floods, acts of God, and incidental or consequential dama­ge caused by defects with other components of the solar system. This warranty does not extend beyond the original cost of the FRONIUS IG Solar Inverter.
FRONIUS IG Solar Inverter Models: FRO­NIUS IG 2000 / 3000 / 2500 LV / 4000 / 5100 / 4500-LV

Should your inverter be replaced at some future date, Fronius will accept the obsolete equipment back and provide for its proper recycling.
Disposal of obsolete equipment
Recycling
- The warranty period of any repaired or replacement inverter is 12 months after shipment from FRONIUS USA or the original warranty period which ever is later
- Labor costs related to uninstalling the defective equipment and re­installing the repaired or replacement equipment are not covered under the warranty.
Some states do not allow the exclusion or limitation of incidental or conse­quental damages. This warranty gives you specific legal rights, and you may also have other rights, which vary from state to state.
