Introduction GeneralDescription 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.

When input power is first applied to the Ampt-CU, all LEDs are on continuously for several seconds. Then the Com LED flashes amber while software is booting. Once boot up is complete and the Ampt-CU is operating normally, both the Power and Com LEDs are on solid green.

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:
LivevoltagesmaybepresentonthePoEcables. Figure8:GenericPoweroverEthernet(PoE)connectiondiagramfollowtheinstructionsforyourdevice 1. Route the Ethernet cable through the feed-through and cable locks. An example is shown below. Figure9:Ethernetcableroutingandconnection 2. Connect the cable to the Ethernet port. 3. Twist the ends of the cable locks together to hold the cable in place. Note:

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 18 Chapter 2: Installing the Ampt-CU Figure10:NetworkSettingsHomeScreen 7. Follow the onscreen directions for each task. RestoringFactoryDefaults The network settings and password can be restored to factory default values by pressing and holding the Restore button during the boot process. If you are using this feature to restore the password, be sure to record your network settings first. See Configuring the Ampt-CU Network Settings on page 18 for more details. To restore the network settings and password:
1. Press the Restart button 2. The LEDs will be on continuously for several seconds. 3. When the Com LED flashes, press and hold the Restore button until the Com and Fault LEDs alternate flashing. 4. The network settings and password are restored and the unit automatically reboots.
