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.
