I have a question regarding a possible master–slave inverter configuration with separate battery banks.

Current situation / plan:

• Battery model A: Felicity LUX-Y-48300LG01 (15 kWh)

• Battery model B: Felicity FLB48314TG1 (16 kWh)

• Inverter model: Deye 6 kW hybrid

Since these two battery models should not be mixed on the same inverter (especially in closed-loop BMS operation), I would like to understand if the following setup is supported and works reliably:

• Two Deye inverters configured in a master–slave (parallel) configuration

• Each inverter connected to its own dedicated battery bank

  • Inverter 1 → LUX-Y-48300LG01

  • Inverter 2 → FLB48314TG1

• Each inverter communicates only with its own battery BMS (closed loop)

• No batteries shared or paralleled between inverters

Questions:

1. Is this architecture supported by Deye?

2. Will the master–slave inverter communication work correctly if each inverter has a different battery model and capacity?

3. Are there any known limitations regarding SOC synchronization, charge/discharge coordination, or fault handling in this setup?

4. Any specific configuration settings or precautions recommended?

The goal is to keep each battery system electrically and logically independent, while still operating the inverters together as a single system.

Thanks in advance for any insights or real-world experience.
