Unpacking and inspection

The packaging components must be removed and disposed of according to the applicable regulations of the

country where the device is installed.

Upon opening the packaging, check the integrity of the equipment and verify that all the components are

present.

If you notice defects or deterioration, stop the operations and call the carrier, as well as inform ABB Service

immediately.

Please keep the packaging in the event it has to be returned; the use of inadequate packaging will void the

warranty.

Always store the Quick Installation Guide, all the supplied accessories and the AC connector cover in a safe place.

Do not open the inverter in case of rain, snow or high

humidity (>95%). During the installation, do not place the

inverter with the front cover

facing the ground.

Install the inverter by following this procedure:

• Place the bracket

level on the wall and use it as a drilling template.

• The selection of the appropriate number and distribution of the anchors

is the responsibility of the installer. The choice must be made according

to the type of wall, frame or other type of support, and should be sized

considering a total load of more than 4 times the weight of the inverter

(total 4x15=60 kg total). Depending on the type of anchor chosen, drill the

holes required for the xing of the bracket (Figure

• Fix the bracket to the wall or structure.

• Carefully lift the inverter and hook it onto the bracket by inserting the two

supports in the slots on the inverter (Figure

• Proceed to anchor the inverter to the bracket by installing the two (one

each side) locking screws (Figure

• Install wireless antenna by screwing it into the dedicated connector

located on the bottom part of inverter

(Figure

WARNING! ELECTRIC SHOCK HAZARD! Hazardous voltages may be present inside the

inverter. The access to the internal zones of the inverter must be carried out after a minimum

waiting time of 5 minutes since the inverter was disconnected from the grid and from the

photovoltaic generator.

• The main connections are made on the lower part (outside) of the inverter. To install the accessories and make the necessary

connections, unscrew the 8 screws using a TORX T20 key and open the front cover

; while removing the screws, pay

special attention since additional screws are not supplied.

• After making the connections, close the cover by tightening the 8 screws on the front, while respecting the sequence and

tightening torque (2.5 Nm).

Place and position of installation

- Refer to the technical data for the verication of the environmental conditions to be

met.

- Do not install the inverter where it is exposed to direct sunlight. If necessary, use

protection that minimizes the exposure, especially for ambient temperatures above

40°C/104°F.

- Do not install in small unventilated spaces where the air cannot circulate freely.

- Always ensure that the airow around the inverter is not blocked to prevent

overheating.

- Do not install near ammable substances (minimum distance 3 m/10 ft).

- Do not install on wooden walls or other ammable substances.

- Do not install inside residential premises or where a prolonged presence of people

or animals is planned, due to the acoustic noise that the inverter produces during

operation. The noise emission value is strongly inuenced by the installation

location (e.g. type of surfaces around the inverter, general properties of the room,

etc.) and the quality of electricity supply.

- Install on a solid wall or structure that is suitable to support the weight of the

equipment.

- Install in an upright position with a maximum inclination as shown in the gure.

- Respect the minimum distances indicated. Choose a location that allows enough

space around the unit to allow easy installation and removal of the equipment from

the mounting surface.

- Where possible, install at eye level for easy viewing of the LEDs.

- Install at a height that takes into account the weight of the equipment.

- When installing multiple inverters, position the inverters side by side while

maintaining the minimum distances (measured from the outer edge of the inverter);

if the space available does not allow this provision, position the inverters in a

staggered layout, as indicated in the gure, in order to make sure that the heat

dissipation is not affected by the other inverters.

- All installations at altitudes above 2,000 m/6,500’ must be assessed on a case by case basis with ABB Service to determine the proper derating of the input

parameters.

The nal installation of the inverter must not compromise the access to any disconnection devices located outside.

Refer to the warranty conditions to evaluate the possible exclusions related to an improper installation.

Check the correct polarity of the input strings and the absence of earth leakages of the PV generator. When the PV panels are exposed

to sunlight, they provide a continuous voltage (DC) to the inverter. Access to the internal inverter zones must be carried out with the

equipment disconnected from the grid and from the PV generator.

Caution! The inverters referred to in this document are WITHOUT AN ISOLATION TRANSFORMER (transformer-less). This type involves the

use of PV panels of an isolated type (IEC61730 Class A Rating) and the need to maintain the PV generator oating with respect to earth; no

generator pole must be connected to the ground.

If multiple strings are connected to the same input, they must have the same type and number

of panels in series. ABB also recommend they have the same orientation and inclination.

Only for the 5kW model. If the input strings are connected in channels with independent mode,

keep in mind that channel 1 (IN1) supports 19A while channel 2 (IN2) supports 11.5A.

• Observe the maximum input current with respect to quick-coupling connectors. Refer to “String inverters -

Product manual appendix” document available on the site www.abb.com/solarinverters, to nd out the make and

model of the quick-coupling connector used on the inverter. Depending on the model of the connectors installed

on your inverter, it will be necessary to use the same model for the corresponding counterparts (by checking the

manufacturer’s website or via ABB for the compliant counterpart).

The use of non-compliant counterparts with respect to the quick-coupling connectors models

present on the inverter, may cause serious damage to the unit and result in the immediate

loss of warranty

• Connect the DC input, always checking the tightness of the connectors.

• Versions of the inverter which are equipped with two independent input channels (i.e. dual maximum power point tracker, MPPT), can be congured as parallel

(i.e. single MPPT).

Conguring Input Mode to Independent (default conguration)

This conguration is set at the factory and involves the use of the two input channels (MPPT) in

an independent mode. This means that the jumpers (supplied) between the positive and negative

poles of the two DC input channels

must not be installed, and that the independent channel

mode should be set during the commissioning phase, in the dedicated section of the internal

webserver “SETTINGS > SETUP DC SIDE > INPUT MODE”.

ABB declares that the ABB high frequency inverter without a transformer are not manufactured to inject continuous currents of ground fault, and therefore, the

differential installed downstream of the inverter, type B according to IEC 60755/A 2, is not required.

Characteristics and sizing of the line cable

The cable should be three-pole. The section of the AC line conductor must be sized in order to avoid unwanted disconnections

of the inverter from the distribution network due to high impedances of the line that connects the inverter to the point of supply

of electricity.

For the grid connection of the inverter, 3 connections are needed: ground, neutral and phase. The ground connection of the inverter is mandatory.

The connection of the network cable to the inverter is performed by means of the dedicated AC output connector

, by doing the following:

1. Remove the connector head by pressing on the two retaining clips and

then loosen the cable gland.

1a 1b

2. Insert the cable into the connector and cut the cable to length

Make sure that the cable bend radius is greater than 4 times the cable

diameter

3. Prepare the cable according to the following measurement:

(*): Use properly crimped ferrules only on stranded wire with a conductor

section values between 1.5 - 4 mm².

4. Install the individual wires (phase, neutral and ground) on the connector

head according to the instructions printed on each of the three terminals

(tightening torque 0.8...1 Nm)

5. Close the connector and tighten the cable gland respecting the tightening

torque (4+1 Nm) to ensure the IP65 degree of protection

6. Remove the pre-installed protective cap on the inverter.

Insert the counterpart in the AC output connector

while taking care to align

the references (present in both connectors) that prevent connection errors.

To maintain the IP protection rating of the inverter, it is mandatory to install the counterpart with the AC cable connected or the protective

cap, on the AC output connector. In addition, the connector must not be subjected to tensile forces (examples: do not connect weights to

the AC cable, do not leave excess wire hanging, etc.).

Before proceeding with commissioning, make sure you have carried out all the following checks:

-Check the correct connection and polarity of the DC inputs, and the correct connection of the AC output and ground cables.

-Check the sealing barrier of the cable ducts and installed quick-t connectors to prevent accidental disconnections and/or

avoid compromising the IP65 environmental protection rating.

Commissioning is carried out via Wi-Fi connection to the inverter web user inteface. Initial setup must therefore be carried out via a tablet, notebook or smartphone

with a Wi-Fi connection.

To establish the connection and operate with the inverter, it is necessary to connect its input to the DC voltage of the photovoltaic panels.

•Supply the inverter with DC input voltage from the photovoltaic generator and via AC GRID voltage.

Make sure that the irradiation is stable and adequate for the inverter commissioning procedure to be completed.

SCAN this QR code (it is also reported in the inverter pre-commissioning yer inside the box of the inverter). An internet

browser page showing the step by step procedure will be open.

The information contained in this QR code is the IP address of the web user interface of the inverter:

http://192.168.117.1

Recommended browsers: Chrome from v.55, Firefox from v.50, Safari from V.10.2.1

- DEVICE USED LAPTOP.

Open an internet browser page and insert http://192.168.117.1 on the address bar.

STEP BY STEP COMMISSIONING WIZARD:

• STEP 1 - Administrator/User login credentials

- Set the Administrator account user and password (minimum 8 character for password):

Administrator account can open and view the contents of photovoltaic site. Additionally, they can make changes to inverter settings. User and password are CASE

SENSITIVE.

- Set the User account user and (optional) password (minimum 8 character for password):

User account can only read data. It cannot make any changes. User and password are CASE SENSITIVE.

- Click on “Next” button to proceed to the next stage of the conguration wizard.

• STEP 2 (Optional) - Residential wireless network connection.

The parameters relating to the home wireless network (set on the router) that must be known and set during this step are:

- IP Settings: DHCP or Static.

If you select the DHCP function (default setup) the router will automatically assign a dynamic IP address to the inverter whenever it tries to connect to the user

network.

With Static, the user can assign a xed IP address to the system. The data which has to be entered in order for IP static address assigning to take place will

appear. Complete the additional elds at the bottom of the screen (all the elds are mandatory with the exception of the secondary DNS server).

- Available networks (SSID):

Identify and select your own (home) wireless network from all those shown in the SSID eld (you can carry out a new search of the networks that can be

detected with the Update button ). Once the network has been selected, conrm.

- Password: Wireless network password.

Enter the password for the destination network (if necessary) and start the connection attempt (it will take a few seconds).

- Click on “Connect” button to connect the inverter to the home wireless network.

- A message will ask for conrmation. Click “Next” to connect the inverter to the home wireless network.

- Once the inverter is connected to the domestic wireless network, a new message will conrm that.

The message provides the IP Address assigned by the home wireless network router to the inverter that can be used each time you want to access the internal

webserver, with the inverter connected to the home wireless network. Take note of it.

- Click on “Next” button to proceed to the next stage of the conguration wizard.

The IP address assigned may vary for reasons connected to the wireless home router setup (for example, a very brief DHCP lease time). If

verication of the address is required, it is usually possible to obtain the client list (and the corresponding IP addresses) from the wireless

router administration panel.

If the inverter loses the connection with the home wireless network, it is available accessing the Wi-Fi network ABB-XX-XX-XX-XX-XX-XX, where “X” is an hexadeci-

mal number of the MAC Address.

The most common causes of losing connectivity might be: different wireless network password, faulty or unreachable router, replacement of

router (different SSID) without the necessary setting updates.

• STEP 3 - Date, Time and Time zone

- Set the Date, Time and Time zone (The inverter will propose these elds when available).

When it’s not possible for the inverter to detect the time protocol, these elds have to be manually entered.

- Click on “Next” button to proceed to the next stage of the conguration wizard.

• STEP 4 - Inverter country standard, Input mode, Meter and Energy policy.

Country standard

Set the grid standard of the country in

which the inverter is installed.

Input mode

- Indipendent

- Parallel

Meter

None (installation without meter)

REACT-MTR-1PH (single-phase)

ABB 3PH (three-phase)

ABB 1PH (single-phase)

Energy Policy

Zero injection

Self consumption

Custom

From the moment that the grid standard

is set, you have 24 hours to make any

changes to the value, after which the

“Country Select > Set Std.” functionality

is blocked, and the remaining time will

have to be reset in order to have the

24 hours of operation available again

in which to select a new grid standard

(follow the procedure “Resetting the re-

maining time for grid standard variation”

described in the relevant section).

See the relevant section of this guide

to know how to physically set the input

mode

If the selected meter is three-phase addi-

tional requested elds will appear:

- Meter Phase: select the phase to which

the inverter is connected.

When a meter type is selected is possible

to set also the Energy Policy elds that

allows to manage the energy produced

by the PV plant.

- Zero injection: The system automatically

manages power ows in order to avoid

the injection of energy to the grid.

- Self consumption: The system automat-

ically manages power ows in order to

maximise self-consumption.

- Custom: The system automatically

manages power ows in order to avoid

feeding the grid with power greater

than: PDC x Plim where PDC is the

power of the photovoltaic generator

(“PV GENERATOR POWER” param-

eter) and Plim is the output power limit

with respect to PDC(%) (“FEED-IN

POWER” parameter).

- Conrm the settings by clicking “DONE”; the inverter will reboot at the nish of the meter test phase (if installed).

After the wizard is completed, the system will power-on. The inverter checks the grid voltage, measures the insulation resistance of the photovoltaic eld with

respect to ground and performs other auto-diagnostic checks. During the preliminary checks on the parallel connection with the grid, the “Power” LED keeps

ashing, the “Alarm” and “GFI” LEDs are off.

If the outcome of the preliminary checks on the grid parallel is positive, the inverter connects to the grid and starts to export power to the grid. The “Power” LED

remains xed on while the “Alarm” and “GFI” LEDs are off.
