Supported models

• MIN TL-X/TL-XH/TL-AH (US) models
• MID, MAX & MAC TL3-X models
• MAX 1500V, MAX-X LV models
• MOD TL3-XH models
• MIX Storage models
• SPA Storage models
• SPH Storage models
• ShineWIFI/4G/Lan-X (4G/Lan-X: connect the Teleport directly to the inverter via RS-485)
• Shine Master X (slow response time)
• Smart Energy Manager
  • SEM-X (slow response time)

The following Growatt products are not supported, as well as all inverters that do not support the Modbus protocol.

Modbus RTU over RS485

1. Connect the serial cable between the serial port of the Teleport and the serial port of the Growatt inverter.

   Warning

   When connecting the RS485 wires to the terminals of the inverter and the Teleport, Growatt may not follow the industry standard of labeling the negative terminal as A and the positive terminal as B. Please consult the installation manual of the inverter or contact the OEM when the manual does not offer clear instructions. From experience, we have seen the following works:

   • D- of the Teleport connects to pin 4 of the inverter, Growatt calls this RS-485 B.
   • D+ of the Teleport connects to pin 3 of the inverter, Growatt calls this RS-485 A.

2. On the inverter’s LCD display, go to Settings, follow the inverter’s user manual to enter the password: 123, and then navigate to COM Address. In the case of a single inverter, verify the COM Address is 1. In the case of multiple inverters, please set each inverter to a different address and let us know these addresses.

3. Verify the following settings:

   • Baud rate: 9600
   • Parity bit: none
   • Data bit: 8
   • Stop bit: 1

Modbus TCP over ethernet

Note

As far as we know Modbus TCP is only supported by the Shine Master X, so these instructions are specific to that device.

1. Connect an ethernet cable between the router and the Growatt device, as well as between the router and the ETH1 port of the Teleport. Please navigate to our appendix for more instructions on how to integrate with a router.
2. Navigate to the web interface of the Growatt device and go to the System Settings, Communication Parameters and Server menu.
3. In the Modbus TCP section of the Third-party network management tab, configure the following properties.
   • Connect Enable: Enable (not restricted)
     Optionally Enable (restricted) can be selected and the IP of the Teleport added as one of the client IP’s.
   • Addr Mode: System address
   • Logger Addr: 0
4. Click Submit to save and apply the settings.
