<div>Below is what I use from Schneider for 200A grid-tie. They finally made it easy, not inexpensive though. Offgrid version firmware out in the fall.</div>

<div dir="ltr">Hello Wrenches,
<div> </div>
<div>Is anyone aware of a remote load shedding solution that doesn't require additional signal wiring to the loads?</div>
<div> </div>
<div>Generac has a great solution for this that they adapted from their generator business called a Generac Smart management module. Its a 2P x 50A relay that monitors line frequency going to the load and it will trip it off line when the frequency sags. The inverter does a small wiggle that will trip it offline based on some Dip switch settings. on the unit. This really simplifies code compliance in some cases.</div>
<div> </div>
<div>I'm wondering if there are any other more general solutions out there for this.</div>
<div> </div>
<div>Thanks in advance!</div>
