This is really suspect. Note these two quotes: "Orison will automatically store energy when utility rates are low, and then use that energy to power your home or business when rates are high. During a power outage, it will automatically power your home or business and make sure none of your stored energy is sent back to the grid." and: "Simply plug it in like you would any other appliance, and you’re done. Orison automatically begins working. No permits, construction, or wiring required." Unless your home already has a transfer and isolation switch installed [which would require permits, wiring, and possibly construction], "simply plugging" this in will not prevent power from being back fed to the grid during a power outage. Which right there would be a violation of the electrical code in most locations. Why? Because homes back-feeding the grid during outages result in an electrocution risk for any linemen working on restoring the grid to operation. So, as described, this will never meet electrical code requirements, and "simply plugging it in" would be a huge safety and possibly legal issue for the owner.
