Hey, supporting here. I'm trying to connect to a pylontech SC0500 and cannot manage to have a working setup. However, after a few spying, the CAN link seem to work, but nothing on the RS485. And when the X1 detects the bms, then after 30 secs I get the IE 07 bat volt fault. and cannot go...

Hey, Can you post the charging/discharging time period settings? Cheers

I can't deny that. Their profit driven bad move will surely backfire one day. I couldn't resolve to swapping the inverter. My long autonomo_s dream would have suffered...

Hello there, Have you had the chance to review the charging period settings? Many had problems with that when batteries were not charging. Also, is the battery pack recognized? I had troubles with my pylontech setup, and had to go to inextricable contraption to make them work. Cheers,

What is the protocol battery kind you use in the 1877 frame?

I've just read the request you had. And yes their support is willing to send older firmware, although they give big warning with it. but still, I managed to retrieve real old versions. contact me if you need some

Dear Solax fellow, I've been struggling to get my pylontech HV to work with the G4, but I managed. I can assist, but in my case, it required a man in the middle board to "convert" the protocol. Also, I managed to wire only a single H48050 pack, and it works pretty nicely (although the amps are...

Experimentation I made on my side suggest that spoofing a correct battery kind in the 1877 frame circumvent the IE07. Also in 1875 frame (IIRC) there is a battery count byte, and messing with either the battery count or the battery kind trigger the IE07. Could you elaborate on your setup? I may...

Actually, my inverse runs ARM 1.30 and DSP 1.31, but displays 2.03 and 2.07 just like yours. Their internals are epic (I've reverse-engineered most of the ARM firmware, and definitely, it's quite the :poolparty:) Anyway, a firmware upgrade won't forcefully solve your IE07 problem

I've never tried with lead acid batteries with the X1G4. I know there's a setting to switch to that mode. I guess this is what you tried? Cheers,

What info do you have i! the status > battery panel ? number of line and version etc.. I'm afraid we'll have to resort to hardware spoofing. From my experience, and the response from the solax support is that they haven't had a meeting with the pylontech team is a while to ensure compat. (and...
