This is really suspect.  Note these two quotes:<p>&quot;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.&quot;<p>and:<p>&quot;Simply plug it in like you would any other appliance, and you’re done. Orison automatically begins working. No permits, construction, or wiring required.&quot;<p>Unless your home already has a transfer and isolation switch installed [which would require permits, wiring, and possibly construction], &quot;simply plugging&quot; 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.<p>So, as described, this will never meet electrical code requirements, and &quot;simply plugging it in&quot; would be a huge safety and possibly legal issue for the owner.
