Easysolar-II GX ESS Error in DDC Program

Hi there !
I just installed an Easysolar-II GX with 2 x Pylontech US2000 batteries and have "Error in DDC program" alarm.
I added the ESS Assistant with VE-Configure but it does not appears on the GX Remote Console.
Also, on the Easysolar LCD, HUB-1 is displayed.
So maybe there is a conflit between HUB-1 an ESS Assistant ? (But I do not have HUB-1 assistant setup in VE-Configure).
Any help is welcome
Thanks in advance

I tried to "clean" the Assistants with VE-Configure and reinstall the ESS one, but the problem is the same.
I got "#6 DDC program error" alarm ..
I really don't know what can cause this error :-(

Are the Pylontech Batteries correctly connected to the GX Device and shown in the Remote Console ? Correct Communication Cable ... Type A or B ... used ?

Yes, they are well connected and they are charged by the MPPT, which is stopped because they are full. It's the Multiplus II who is in a strange state alternating between "OFF" and "UNKNOW" state.

Never saw that error.

All FW up to date?

What components do you have (list all)?

Check the data wiring. Do you use DIY cables?

Yes, all firmware up to date.

- EasySolar II GX :
-> SmartSolar Charger MPPT 250/70 v1.59
-> MultiPlus-II 48/3000/35-32 (ACOut2 switchable) v497
-> Venus GX v2,87

- 2 x Pylontech US2000C :
- VE.Can to Bus-CAN Type A Cable (with dongle on 2nd RJ45 GX side)

- ET112 meter on grid side
- Only AC In used (for now) on the MultiPlus (parallel installation)

The GX sees the Pylontech batteries BMS.
The GX does not see the ESS assistant installed via VE-Configure.

I can give you remote access if you want to take a look ?
(I've someone on site if any manipulation is needed)
Thanks !

I just noticed that you have 2 MultiPlus (the EasySolar is basically a MultiPlus).

Do you have configured them to work together (parallel, split-phase, or whatever)?

If not that is the problem.

Both system are totally independent. (my house and a friend's one)
I finally disconnected the BMS cable from the Pylontech batteries and reconfigured the EasySolar the same way as my installation, which use a DIY LiFe4po battery pack, and it works now in ESS mode.
I'll take time later to connect it back and see if the problems are back too !
Thanks for your help

Dear all !
One month later ... and the problem is still present :(
I've used the system without connecting the Pylontech battery's BMS for some time, but it's not a solution as the ESS does not monitor the battery SOC, and the batteries goes in alarm when discharged.
I've made last week a call to my vendor (Myshop-Solaire) but they did not respond at all ! (very bad client service this company :)

Any help is welcome, and if one want to "play" with my system, I can provide him full remote access !
(and will offer a pack of beer if you find the problem ! ;)

I began to desperate .. really !
