September 28, 20232 yr I can find plenty of info for Growatt ES Inverter and Hubble comms but not TL. Cannot get AM2 and TL to communicate. I believe the cable pins are correct but cannot find correct setting 5/36 information. If I try the settings for ES models, the system throws a low voltage error after about 10 seconds, and disconnects. I have a totally off grid system.
