Chapter 2: Installing the Ampt-CU 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.
Specifications System Layout PV block size Up to 3200 kWp DC Ampt converters per Ampt‐CU Up to 2000 Example of layout 125 strings x 16 modules/string = 2000 Ampt converters Maximum radio communications operating range 200 m radius Data Communications Interface with data monitoring system Modbus / TCP Connection with data monitoring Ethernet 10/100 Base T Interface with Ampt converters Two‐way wireless Resolution Measurement accuracy Amperage: ±0.
Chapter 2: Installing the Ampt-CU Modbus Register Map Ampt StringView records use the SunSpec protocol for device ID and variable record length, enabling site-specific operation. The SunSpec Common Model precedes the map below. Contact Ampt or one of our monitoring partners for more information.

RS‐485 port Reserved for engineering use Termination switch Reserved for engineering use. Reset button Pressing this button forces the Ampt‐CU to reboot.
Understanding the Status LEDs The Ampt-CU has three status LEDs. 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. Name State Description Power Continuous Green Input power supply voltage exceeds the minimum threshold. Com Flashing Amber Software is booting up.
Chapter 2: Installing the Ampt-CU Chapter 2: Installing the Ampt‐CU This chapter addresses the following topics: Installing the Ethernet Cable Feed-through Mounting the Enclosure Connecting Power Over Ethernet Configuring the Field Computer Network Settings Restoring Factory Defaults Copyright 2014 AMPT, LLC.
Installing the Ethernet Cable Feed‐through A liquid-tight wire grip is recommended for the Ethernet cable feed-through. The markings on the bottom of the unit show where to make a hole for the wire grip. Install liquid‐tight wire grip in this area Figure 4: Bottom view of the communication unit 1. Make sure the communication unit is not powered up. 2. Use a drill or punch to create a hole for the wire grip within the marked area.
Chapter 2: Installing the Ampt-CU 3. Install your wire grip. An example is shown below. Figure 6: Example of an installed liquid‐tight wire grip Copyright 2014 AMPT, LLC.
Mounting the Enclosure Connect the hardware as shown in the figure below, or using a similar method, to mount the Ampt-CU enclosure. Figure 7: Mounting hardware for Ampt‐CU Note: The 1‐5/8” washer (number 5 above) is recommended for strut and uneven mounting surfaces. Note: If a vertical pole is used behind the Unistrut, it should be placed near the horizontal center of the Ampt‐CU. ID Description 1 4 each ¼-20 x 1.
Chapter 2: Installing the Ampt-CU 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.
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.
