Tesla dumps larger Powerwall option and gears up for Mark II release
Sales of the smaller 7 kWh option, which Tesla calls the “Daily Powerwall,” will continue. That model can also store solar and wind energy and even take advantage of net metering (feeding excess electricity to the grid in exchange for credit), which is a huge selling point for many homeowners looking to get a little more independence from local utility companies. However, the Daily Powerwall can still act as a “backup” just like the 10kWh option by charging up from the grid when utility rates are low, allowing homeowners to switch to battery power when the rates go up. Homeowners can also link up multiple Powerwall batteries to increase storage capacity – if they really need it.
