TESLA’s PowerWall2 coming to Canada (Last updated December 9th, 2016) With double the energy of our first generation battery, Powerwall 2 can power an average two-bedroom home for a full day. Compact, stackable and with a built-in inverter, installation is simple, either indoor or outdoor. Last fall, Tesla Energy moved production of Poweralls to the partially finished Nevada Gigafactory, assembling them from batteries that come from Panasonic, their main supplier. But starting the second half of 2016, the Gigafactory should start producing Tesla’s own batteries (still in partnership with Panasonic), which should be better and cheaper than Panasonic’s current cells. This timing is probably not a coincidence. The Powerwall Version 2.0 is probably designed to use Gigafactory batteries. In facto, demand for these stationary battery systems – not just residential but also for utility/commercial use – are probably factored in Tesla’s plan to ramp up Gigafactory production enough to get economies of scales, and thus lower costs, by the time the Model 3 starts rolling out. Tesla Powerwall 2: What is it? The original Powerwall is a lithium-ion battery that comes as a single unit or in multiples for those who need more power. It stores excess energy produced from your own solar generation (so that energy not used at the time will be available later) and can store power when electricity from the power grid is at its cheapest rate (off-peak). And it is able to juice up everything in your house. From a 0.2kWh fridge to a 2.3kWh washing machine, the 7kWh or 10kWh Powerwalls should be able to keep you running. For those that know their electricity consumption numbers, the Powerwall offers continuous power at 2kW with a peak power output of 3kW.
