This is what the fuss is all about – Elon Musk’s newest venture is the Tesla Powerwall, a home battery that’s promising sustainable energy storage.
The Tesla Powerwall comes in two guises: the Powerwall 10 kWh that costs $3,500 and it’s intended for backup applications, joined by a 7 kWh variant that’s $3,000 and is meant for daily cycle applications. Warranty? Ten years as standard, with an optional ten-year extension.

In terms of dimensions, the Tesla Powerwall home battery is 33.9 inches (86.1 mm) wide, 51.2 inches (130 cm) tall and 7.1 inches (18 mm) in depth. The wall mounted lithium-ion battery is rechargeable, and it comes with liquid thermal control to keep things nice and cool at all times.

Weighing 220 lbs (100 kg), this isn’t what one might call a portable power bank charger. The Tesla Powerwall’s generous dimensions and electric storage capacity make it the perfect addition to your garage if you’re the owner of a Model S or, in the nearest of futures, a Model X.

With a 92 percent round-trip DC efficiency, 2.0 kW continuous and 3.3 kW peak power at 350 to 450 volts, the Powerwall is pretty impressive. In terms of current, the official specifications sheet claims 5 amp nominal and 8.5 amp peak output. Of course, the Palo Alto-based outfit’s newest product is single and three-phase utility grid compatible.

For installation, Tesla recommends a trained electrician and an AC-DC inverter that isn’t included as standard in either of the Powerwall packages. Despite its beautiful shell and functionality, the Tesla Powerwall has an ace up its sleeve – it can recharge solely from solar panels.

On a side note, the Tesla Powerwall can automatically charge itself when utility rates are low, amassing enough electric energy to power your house in the evening or when a power outage comes into play.
