Connect and configure Growatt TL, TL-X, TL-XH inverters

Overview

Follow the steps below to connect one of the following inverters to SolarAssistant:

• Growatt TL-X, TL-XH, TL3-X, TL3-XH

Step 1 - Connect inverter monitoring cable

The USB port on the inverter can not be used for monitoring. You need to connect it via a RS485 cable by screwing the RS485A and RS485B wire into pin 3 and 4 of the communication port. Each inverter will require it's own USB cable.

You can also explore alternative RS485 adapters that might be available locally in your country.

Step 2 - Configure SolarAssistant to connect to a Growatt MIC/MID/MOD inverter

On the configuration page, select "Growatt" as your inverter model.

Each RS485 USB cable will show up as a USB device. Select all ports that are connected to Growatt inverters.
