The way especially Americans talk about backup battery solutions confuses me. The Tesla Powerwall is spoken of as though it were a particularly unique innovation, and it's apparently news for Toyota to unveil an...8.7kWh battery. They just seem like par for the course to me, on the way too expensive side even. Then again most of the products that have existed in this space/have been deployed in the developing world are from India and China, so it's perhaps not surprising that Westerners haven't been drooling over those.
