So my system design is a bit unconventional since I'm building it around 40KW of used LTO modules that came from used EVs. Each of the 36 modules will be paralleled into two separate Square D QO load centers, each with a dedicated 2 pole breaker. I'm using two load centers because each will hold only 20 spaces for the 2 pole breakers and I'll need 36 spaces total for all the batteries. Because of this, I will be joining 4/0 wires coming from each load center onto a common busbar before sending the single 4/0 wire into my Sol-Ark 12k inverter.
I'm looking for a way to isolate one half of the battery bank (18 modules connected to a single load center) with a disconnect switch. The other half of the battery bank/load center would also get a disconnect switch. Because the LTO modules I'm using cycle between 48-60V I'm having a hard time finding a DC disconnect that can support 60V and 300+A. Any recommendations?
I'm also curious that without a disconnect switch, if I were to turn off the breakers in one load center would there be any potential problems if I'm still drawing electricity from the other load center?
