The pricing is attractive. Not sure how this helps with EVs though; you'd still be reliant on buying off peak power for charging.
No, it's not a complete solution as is and that's not unexpected. An off-grid building needs two bits of electronics - a battery charger that interfaces the PV panels to the battery, and an inverter that sits between the battery and the house's 120V and possibly 240VAC grid. The vast majority of people with grid-tied PV have an interface between the PV and power grid that only works when the sun's shining and cannot work with a battery - so there's no load-shifting or backup power.LTLFTcomposite wrote:This doesn't look nearly as cool as first thought, the specs say it doesn't include an inverter. I was hoping for a "just add solar panels" solution.
I thought I heard Elon say the $3500 was for 'installers' and assumed wholesale. I see on the Powerwall site, though, that it's listed as $3500 without qualifiers.LTLFTcomposite wrote:Supposedly $3500 for 10 kwh
The 10kWh model will run an efficient off-grid house for 2.3 days...Both are guaranteed for ten years and are sufficient to power most homes during peak evening hours

It wouldn't make good business sense to not use the same battery design. Why do you think that liquid thermal management is a bad idea for BEVs and 'home' use?

IMO, LTC/ATM is generally a bad idea for BEVs, and perhaps even more of a disadvantage in small-scale stationary installations.
The prices are pretty cheap per unit, but remember, the vast majority of buyers will need to install multiple units in their installations, to power conventional high-kWh demand homes when the sun isn't out, or when the grid is down.
An S owner who buys ~10 of these so they can do a mid-day Summer recharge with off-peak kWh, is going to have one hot garage...
