Thank you. I'll play with swapping cables, batteries and bms's this weekend.

I think I found where the problem comes from. In the case where there is communication between the inverter and the BMSs, the maximum current is taken from the BMS settings. For the tests, I disconnected the connection between the inverter and the BMSs, and configured the inverter to monitor the...

I've watched Andy's videos, they are very helpful and I've learned a lot from them, but I still couldn't solve my problem. I think there is some problem in the BMS-Inverter communication and even though the two devices are talking they can't understand each other.
