<p>What voltage LG battery? 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.</p>

<div id="__MailbirdStyleContent" style="font-size: 12pt; font-family: Arial; color: #000000;">You would need a shunt trip rated @600vdc , 25 amps I'm guessing. 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.
<div>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</div>
<div>back and forth.<br />

<div id="m_-69264809370344934__MailbirdStyleContent" style="font-size: 12pt; font-family: Arial; color: #000000;">Hello,
<div>Any of you ever use a 120vac-enabled shunt trip breaker on the inverter output at the main load panel, and have it controlled by a small AC disconnect switch outside?</div>
<div>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.</div>
<div> </div>
<div>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.<br />
