Chapter 2: Installing the Ampt-CU Copyright2014AMPT,LLC.7 Chapter1:Introduction GeneralDescriptionThe Ampt communications unit (Ampt-CU) provides wireless two-way communication with every Ampt converter The Ampt-CU links to your SCADA or monitoring system via Modbus to provide highly accurate and synchronous data. This solution eliminates the need for smart combiners which lowers costs. With Ampt communication, system designers, operators, owners, and financiers gain a level of transparency and predictability unmatched by conventional monitoring solutions. This improved system planning and decision-making capability lowers PV project risk and increases return on investment. 

Chapter 2: Installing the Ampt-CU Copyright2014AMPT,LLC.17 ConnectingPoweroverEthernetYou will need to use a PoE injector that meets the requirements in the Specifications section on page 8. The diagram below illustrates the basic installation of a PoE injector; however, be sure to follow the installation instructions that comes with your PoE device. Caution:LivevoltagesmaybepresentonthePoEcables. Figure8:GenericPoweroverEthernet(PoE)connectiondiagram–followtheinstructionsforyourdevice1. Route the Ethernet cable through the feed-through and cable locks. An example is shown below. Figure9:Ethernetcableroutingandconnection2. Connect the cable to the Ethernet port. 3. Twist the ends of the cable locks together to hold the cable in place. Note:Keepwiresoutoftheantennaareaasnotedonthepanel.
18 ConfiguringtheAmpt‐CUNetworkSettings Note:CompletingthetasksinthissectionshouldbecompletedbyaNetworkAdministrator. Please note the following:  Default IP address of the field computer is 192.168.1.249  Web interface to configure the field computer is accessed via port 8080  Modbus data is accessed via port 502 To configure the Ampt-CU network settings: 1. Configure the TCP/IP settings of your laptop to: a. IP Address - 192.168.1.248 b. Netmask - 255.255.255.0 2. Ensure the Ampt-CU is powered up. The Power LED should be on and solid green. 3. Connect your laptop to the field computer using the Ethernet ports of each device. If using PoE, the PoE injector must be connected between the laptop and the Ampt-CU. 4. Open your web browser and enter the default IP address (http://192.168.1.249:8080/) in the address bar. 5. Complete the fields on the login page a. Login: admin b. Password: password 6. Once logged in, use the menu on the left to: a. Change your password b. Configure network settings c. Set time zone and network time servers d. Manage the layout file e. Setup communications f. Reference the Modbus map g. View string/inverter currents, voltages, power h. Download string data in CSV format - new hardware will not have any data available until it has been online at least a day with a live system. i. Perform a system test j. Enable Ampt support access k. Reboot the system
Chapter 2: Installing the Ampt-CU Copyright2014AMPT,LLC.19 Figure10:NetworkSettingsHomeScreen7. Follow the onscreen directions for each task. RestoringFactoryDefaultsThe network settings and password can be restored to factory default values by pressing and holding the Restore button during the boot process.
