H3 12.0 E Cannot enable remote control
Posted: Tue Feb 03, 2026 2:40 pm
Hello,
I'm trying to remotely control a H3 12.0E thru RS485 and its not working.
When I go into settings on the inverter -> feature -> remote control -> enable, it just says "fail" and then nothing, I can just try to enable it again and again, no changes or more info. And when my controller talks to it, it just gets a "response not recognized" result.
I dont know which setting it would be in the cloud menu. The 14ASoftwareTrigger maybe? Nothing else resembles a remote control setting in any of the settings.
So I'm asking if anyone knows anything about this issue?
All firmware was uptodate a couple weeks ago, which is the problem maybe because apparently before the 2.06 master version communication protocol was different and supposedly better.
