Fuse size for 2P16S battery bank (560ah)

DominicanRay said:

I recently purchased 64x of the EVE 280 cells.
I have two banks (32 cells each) connected in a 2P16S configuration.
I plan to connect these to a combiner box, and then connect the combiner box to my inverters.
I'm using 2x Deye 8k inverters connected in parallel.

What is the best way to fuse this setup?

Class t fuse as close as possible to the positive terminal.

8000 ac watts * 1.5 low frequency factor / 48 volts = 250 service amps
250 service amps / .8 fuse headroom = 312.5 fault amps.

Deye 8kw data sheet :

• Max. Charging Current (A): 190A
• Max. Discharging Current (A): 190A

depending on the batterie charging voltage the inverter flow is around 190A

how is the amps when u charge the batteries from the grid ?
