LG only sell the high voltage (400dc) in North America. The LG 48vdc was a failure.

Midnight has large (100, 175, 250 A) DC shunt trip breakers that are 125 v rated. They also have 15 and 20 A 600 V rated remote trip breakers.

A DC rated contactor might be better, but where to find either? And what control voltage will the ST or contactor use? I assume its grid-tie if an AHJ is involved. The LG RESU would also require both pos and neg be switched off (ungrounded neg) for code compliance. You are probably best off running the battery leads outside to a 600vdc dp safety switch. And then back it's only 10 ga, wire back and forth.

I say offgrid because I doubt any utility would grid-tie approve as an outdoor disco, it since it does not visibly open the inverter output power wires. But it wound save in round-trip inverter wiring outside and back in to the load center, and perhaps a big AC outdoor disco in larger systems.
