TLC5000 support #42

Closed stoprocent closed 2 years ago

stoprocent commented 4 years ago

Hi Guys

I have seen there was another issue regarding the same, TLC family inverter (Issue #22) and it was never resolved. I've tried the script today but I'm getting a lot of noise on and I'm not sure what is it.

A lot of FF or FD or F1 etc. in quite a regular interval (like 1 sec or less). Is it normal behavior before you send a re-register command? I've tried to send commands trough stript or manually tough console the same result.

The moment I connect the rs485 module to inverter I'm getting constant data on RX (led blinks) but data is rubbish.

I was reading PMU manual and it supports both TL family and TLC so I guess communication protocol is same (as documented here too).

I've tried swapping A and B. Any ideas?

I've also tried different methods by dumping and inspecting TCP traffic from the inverter and it's relatively simple to read the data. The inverter is using MQTT (as I investigate it it's Alibaba Cloud platform as it formats the data according to this documentation) without TLS so all traffic is unencrypted but the problem is it's sending data every 10-15 min which sucks.

That behaviour is not what we see on other inverters. We see dead silence, unless polling.
