Lilygo T-2CAN, emulating Tesla 3 to Sungrow SH6.0 RT

[Zydrius46]

Hi All,
the problem is that inverter work only forced mode for discharging the battery. it does not charge the battery anyhow.
LILYGO shows only discharging action. what could be the problem?

What inverter?

Sungrow SH6.0 RT-V112

From the Discord earlier today we had one Sungrow user report;

The battery would only charge in Self-Consumption mode.
It refused to discharge normally. To get it to discharge, I had to manually switch the inverter into Forced Discharge mode.

I remembered reading something in an Australian Facebook group about how certain “schemas” can block charging or discharging. The new firmware apparently resets the discharge setting.
So I checked it — and sure enough, that was the issue!
Once I corrected the schema setting, everything started working perfectly.So now it’s finally up and running — YES!

I’m wondering if all the problems I had after the firmware update were simply caused by that schema setting getting reset.
On the bright side, the new battery enclosure build looks really neat and tidy — that’s definitely a win.

Thanks for response, but it did not helped much :(
I did update the iSolarCloud, vent through all setting, there everything is in logic.
i have tried to change protocol to Sungrow SBRXXX, and it did changes in iSolarCloud. Now it is shoeingSUNGROW BATTERY as an additional device and data from battery (percentage, voltage...) correspond to data from LILYGO. But it does not react, no charging at all.
I have tried to ChatGPT. It is saying that could be the CAN speed mismatch. Telling probably the speed is 250ms from emulator, and Sungrow requires 100 to 50ms. Could it be the issue? I am not much in programming thing at all, so sorry if it stupid question :)

ChatGPT hallucinates on this topic. It should not be used.

A setting/profile is blocking use for sure in your case. Sorry I am not an expert on Sungrow, this is just secondhand info from the discord!

Hi, @Zydrius46 did you find a solution to this problem? I’m having exactly the same issue with my SH10RT sungrow inverter.
Thanks

Unfortunately did not. I have sold SUNGROW and have bought Solis, that works with no issues.Sent from my iPhoneOn 21 Aug 2026, at 15:14, PANKINA1 ***@***.***> wrote: Hi, @Zydrius46 did you find a solution to this problem?
