<div dir="auto">Hi all,
<div dir="auto"><br />
<div dir="auto">I am trying to figure out best options to control loads in a Sol-Ark15k battery backup residential system. It's been quite a few years since I've set up an automatic load control, and never with a Sol-Ark. The Sol-Ark will output to the main breaker panel, so no separate "backed up" panel - all house loads will likely be on the Sol-Ark's load side. </div>
<div dir="auto"> </div>
<div dir="auto">What do folks like to use in this type of circumstance to automatically shed loads when the grid is down, either sequentially as the battery bank drops down or more simply triggered by loss of grid? Are they pieces of equipment that work specifically with the Sol-Ark? </div>
<div dir="auto">I'd also be open to considering Fortress's Envy, if there is an option that would work well specifically with it. </div>
<div dir="auto">I'm interested in the range of options from simple to complicated, as long as it is automated. All automated ideas/options appreciated. </div>
<div dir="auto">Thanks! </div>
