Page 3 Indicates the existence of a risk that may result in personal injury and/or property damage. If you are in charge of installing, maintaining or configuring the ITR 2.0 you should take the following precautions into account: Refer to the instruction manual before using the equipment.
Page 4 The ITR 2.0 system also offers an added value to the installation, since it performs consumption monitoring tasks, power quality control, and may also allow the user to control certain loads of the installation according to production, providing remote management capabilities.
Page 5 There is also a special type of ITR 2.0 capable of controlling systems incorporating diesel auxiliary generators (this type is not the subject of this manual). The ITR 2.0 monitors the power at the point of connection between the grid, the consumption of the loads of the installation and the photovoltaic generation, regulating, through communication, the maximum power that can be generated by the inverters at any given moment so that energy is never dumped into the grid.
Page 6 Cables conforming to IEC60227 or IEC60245, with a minimum cross-section of 1.5mm must be used to connect the measuring voltages. The ITR 2.0 takes its power supply from the measuring voltage of phase R, so in single-phase systems this voltage phase must always be connected.
Page 7 The use of incorrect current transformers can cause damage to the equipment and the installation. The ITR 2.0 has two current measurement channels, C1 and C2, for each of the phases. Each channel will be used to measure the current of one of the branches of the installation: grid consumption, load consumption or photovoltaic production.

Page 9 LACECAL ITR 2.0 - Self-Consumption and Zero Injection Manager Single-phase installation measuring consumption of the network and consumption of the loads. In installations where it is difficult to connect the two current measurements, it is possible to operate by measuring only the mains consumption. Refer to the specific configuration manual of the inverters used for possible incompatibilities or limitations of this configuration.
Page 10 ITR 2.0 - Self-Consumption and Zero Injection LACECAL Manager In three-phase installations, the same connections previously seen for the R phase will be replicated in the S and T phases. The connection of a Circutor MC3 series three-phase transformer is shown below.
Page 11 LACECAL ITR 2.0 - Self-Consumption and Zero Injection Manager The same connector is used for both types of serial communication. In case the communication is RS485, two external jumpers must be made between pins 1-5 and 2- 4 as shown in the diagram above.
Page 12 EQUIPMENT CONFIGURATION POWER ON AND STATUS LEDS Once all connections have been made, voltage can be applied to the ITR 2.0, which will start its start-up sequence. The current status can be obtained by means of the LEDs on the front panel, the meaning of which is shown below.
Page 13 In normal state (if inverters are configured and all are accessible via communication) it stays on and turns off briefly each time the ITR 2.0 sends a new setpoint to the inverters.
Page 14 ITR 2.0 WEB server. In the initial 'Plant status' screen you can see the rms values of all the measurements: voltages, currents and power per phase of the measurements taken.
Page 15 Manager The first time you access the 'Configuration' menu you must use the generic user password (ITR1234). Only the ITR 2.0 connectivity options can be configured using this password. In this first login you will be asked to create your installer password, which must always be 8 characters long: Write down the installer password assigned to the ITR 2.0 in a safe...
Page 16 ITR 2.0 - Self-Consumption and Zero Injection LACECAL Manager HARDWARE CONFIGURATION • Change direction of current C1: Allows to change by software the direction of all t h e currents associated to the measurement channel C1 in case the physical connection has been made in the opposite direction to the one indicated in the connection section.
Page 17 LACECAL ITR 2.0 - Self-Consumption and Zero Injection Manager • Manufacturer: Selects the manufacturer and communication mode (in case there are several options for the same manufacturer) of the inverters connected to the ITR 2.0. o SMA (SpeedWire) o SMA (RS485)
Page 18 ITR 2.0 - Self-Consumption and Zero Injection LACECAL Manager Two relay control options are available: via one of the outputs of the load control connector located on the top of the ITR or via a remote device controlled by MODBUS TCP protocol.
Page 19 LACECAL ITR 2.0 - Self-Consumption and Zero Injection Manager • Destination IP address: Enter the IP address of the relay control device. • Port number: Enter the TCP port number on which the MODBUS server of the control device is located.
Page 20 ITR 2.0 - Self-Consumption and Zero Injection LACECAL Manager CONTROL CONFIGURATION • Power control mode: In single-phase installations 'Per phase' should always be selected. In three-phase installations, if 'Per phase' is selected, the power of the inverters will be limited so that no energy is dumped into the power grid by any of the phases.
Page 21 (usually the router connecting to the Internet) to obtain the IP address and the rest of the network parameters. o Internet access sharing will create an access point and the ITR 2.0 will behave as a router, with a fixed IP (192.168.138.1) and a DHCP server that can assign IP addresses to other devices connected on the Ethernet network.
Page 22 WIFI CONNECTION CONFIGURATION If a USB WIFI device is connected to the ITR 2.0, this menu allows you to connect to one of the available networks and configure its properties. Page 22 from...
Page 23 You can also configure the connection to a WIFI network that is currently unavailable, and the ITR 2.0 will connect to it when it is in range. To do this, click on the 'Create connection' button on the initial screen, and in addition to the data indicated above, the network name and security type must be entered.
Page 24 In the first section you can download the current configuration of the ITR and also the historical measurement records month by month. These historical files can be later uploaded to the WEB application, in case the ITR 2.0 does not have internet access, in order to visualize the operation from anywhere.
Page 25 WEB platform, it is necessary to have a user account and register the ITR 2.0 in this account. To do this we will use this option in the ITR 2.0 configuration menu and we must also access the WEB application at http://itr.lacecal.es.
Page 26 Again in the WEB platform, enter the data provided by the ITR 2.0 and click on the 'Register' button. If you already have a user account on the WEB platform, you can add ITR 2.0 to your account by simply logging in with your username and password.
Page 27 LACECAL ITR 2.0 - Self-Consumption and Zero Injection Manager PLANT CONDITION In the 'Plant Status' menu we have access to three screens that allow us to visualize the current status of the installation. EFFECTIVE VALUES This screen shows the current values measured in each phase for voltage, current, active, reactive, apparent and apparent power and power factor.
Page 28 It also shows the harmonic analysis up to harmonic number 15. CONTROLLED DEVICES In this screen you can check the status of each inverter connected to the ITR 2.0: current power, percentage of power regulation being applied and status of communication with the inverter.
Page 29 LACECAL ITR 2.0 - Self-Consumption and Zero Injection Manager DATA LOGGING The 'Data Logging' option provides a history of the data collected from the installation, both consumption and total PV production and from each of the inverters. PLANT MONITORING It graphically displays the evolution of total consumption and photovoltaic production on a specific date.

Page 31 B connector. ACCESS VIA ETHERNET NETWORK It is possible to make the ITR 2.0 recover the default IP address of the Ethernet connection by performing the following steps: 1.
Page 32 LACECAL Manager WIFI ACCESS If the ITR 2.0 has a USB WIFI stick connected, it is possible to create an access point and connect wirelessly to the configuration WEB. To do this, the following steps must be followed: 1. Press the button for more than 5 seconds. When released the 'Status' led will start flashing.
Page 33 LACECAL ITR 2.0 - Self-Consumption and Zero Injection Manager 10.1 ALL/NOTHING LOAD CONTROL Up to three independent loads can be switched on and off using the outputs of the load control connector. The active outputs can be selected and programmed in the load control configuration menu.
Page 34 • State to connect the load: determines whether to activate the load the output of the ITR 2.0 should be switched on or off. This would allow the use of relays with normally open or normally closed contacts depending on the need.
Page 35 Typical resistive loads are DHW heaters. The configuration and control of the load is done from the ITR 2.0. The two devices communicate via the Ethernet network (both must be connected to the same local network).
Page 36 Once the ITRv.LD device is connected on the same Ethernet network as the ITR 2.0 you can use the 'Search Drivers' button in the 'List of Available Loads' to search for and add all devices.
Page 37 LACECAL ITR 2.0 - Self-Consumption and Zero Injection Manager The first icon is used to define the network configuration of the charge controller. A fixed IP address must be assigned to the Load Controller. Consult your local network administrator if in doubt to avoid conflicts with other devices.
Page 38 It is also possible to obtain the instantaneous values measured by the ITR 2.0 of voltages, currents, active and reactive powers.
