I looked through the material, but I'm still at a loss how this is different than any recent battery/inverter combination like Ecoflow/Jackery/etc or a UPS with an app. I'm an electrician, and very in to new electrical products but this one just makes me wonder how it's different.
Look up most of those products and you can see that they aren’t meant to be used daily, kept charged at 100% etc.. This is a commercial energy product scaled down to a consumer level, not a camping battery with a shiny exterior.
Also their apps are bad and don’t offer anything of value.
My current setup is a 2.8Kv generator I haul our of the shed, run a few extension cords to core things like fridge/freezer, internet, office etc.
This is a nice fit between a generator and a Powerwall. Generator is a pain if you have to setup + if not home the fridge stays off or my wife will leave to me unless its urgent. A Powerwall (or similar) is a significant investment.
This product covers people like me with occasional outages but it doesn't have the setup or out of home hassle, and its a more financially accessible solution than a Powerwall. I could def see people interested in this.
