Tesla Energy Launches Second Version of Powerwall

Soon after bringing the first Powerwall energy storage products to U.S. homes, Tesla Energy will be releasing its second version.

The battery storage business has become quite competitive since starting up in recent years. That’s driven Tesla to make its system better and more affordable. Tesla says the second generation Powerwall will be on the market “in a few weeks.”

Powerwall will now be compatible with inverters manufactured by SMA, a global residential PV inverter company. SMA is the world’s largest inverter manufacturer by revenue and second largest by shipments, according to GTM Research.

The Powerwall 6.4-kilowatt-hour unit stores electricity from home solar systems and provides backup in the case of a power outage. Weighing 214 pounds and standing about 4-feet tall, it retails for around $3,000.

The Powerwall was originally designed to work with inverters from Solar Edge. The Powerwall compatible 7.6 kilowatt StorEdge inverter currently retails on WholesaleSolar.com for $2,944.

The version 2 Powerwall also features simplified handling and wiring requirements. Customers will be able to get their units installed for less, saving them even more money. Another change has been installing a fix to excess noise the first Powerwall was making, and that had received a few customer complaints.

Nissan is another automaker to find a market for energy storage tied into its electric vehicle batteries. The U.K.-based arm of the Japanese automaker has entered a partnership with Enel SpA, Italy’s largest utility. That arrangement will let Nissan Leaf and e-NV200 electric van owners sell excess energy back to the grid.

Tesla expects that interest in its upcoming Model 3 will drive increased sales of its Powerwall.

“It should be noted that these folks are not interested only in Tesla Motors, but also in Tesla Energy,” said Jonathan McNeill, Tesla’s president of global sales and service. “The price point of the Tesla Powerwall is an accessible price point for many of these folks, and so they’re expressing interest in both.”
