Wiring 6 batteries with one EG418

[William C]

Hello, I haven’t been able to find any clear information for connecting 6 batteries to one EG418KPv. This is what I have in mind. Can anyone show me my errors?
The plan is to make 3 banks of 2 batteries (EG4 wall mount 48v, 280Ah) wired in parallel (+ to + & - to -) using the 2/0 cables that are supplied with the batteries.
Each bank connected to + & - bus bars.
The bus bars connected to the 18KPv via two positive and two negative 2/0 wires.
The instructions show to, “Use a fused positive battery bus bar rated >=250a per battery or per inverter using Class-T fuses.”
I also see in another set of instructions, “Fused Positive Battery Bus Bar >= 500a Rated Min or >= 250a / Inverter. Class T fuses – 200a @ 58v.”
Not sure what they are saying.
Do I need 6 fuses, one on each + line from a battery?
One fuse on each + line from each bank or, one fuse in each of the 2 + lines to the inverter after the bus bar?
The instructions state that it is possible to use more than 3 batteries but there is very limited information as to how to wire them.
Does anyone have some guidance for me?
Thanks in advance...

NOTE: After learning more about the PowerPro battery and its capabilities, I have updated this and the follow-on posts for clarity and correctness.

There has been a bit of discussion on paralleling the EG4 PowerPro battery. This and the following posts show many of the most common configurations.

The PowerPro battery is in the process of getting UL-certified for putting 3 in parallel using the internal Busbars and supplied cables. EG4 has also started the process of getting UL Certification of 5 in parallel.

If there is a need to go beyond 5 batteries in parallel, there are several...
