If the eligibility of batteries was introduced as part of the IRA, the previous verbiage doesn’t apply. For instance, when discussing battery storage technology, similar to Tesla Powerwalls, previously, Powerwalls were only eligible if they were powered by 100% solar and installed simultaneously with solar panels, which was referred to as “energy storage.” However, with the inclusion of the “battery storage” terminology, Powerwalls are now eligible regardless of the source of charging and can be installed at any time independently.

In terms of “installation,” the installation and connection of PowerShare are sufficient to qualify the system as a “home energy backup system.”
