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...
