巴基斯坦采购需求：电池管理系统、BMS电池、BMS模块、锂BMS、BMS锂电池、Lifepo4 BMS

I've been working with a specific battery management system and an inverter, but I'm encountering a communication issue. The inverter displays an error message, which indicates there's a problem with the setup. I've already tried all available communication protocols on both devices but haven't had any luck. Could you provide guidance on how to resolve this issue? Any specific settings or adjustments you'd recommend that could facilitate proper communication between the BMS and the inverter would be greatly appreciated. I'm eager to get this system working correctly. Thank you!
