I have two UP5000 PylonTech batteries and one Huawei 48V Lithium battery. I'm planning to purchase a Multiplus II GX 48-70/50 inverter. Additionally, I already own a 150/70 MPPT controller. What is the best way to connect my system, including communication cables and fuses? Will I need to buy a separate Cerbo GX, or can I use the VE.Can connection to link the batteries and the inverter?
