The Tesla Powerwall 3 is a large lithium-ion battery designed for home installation. Priced at around $12,000, this energy addition is a hefty investment. Let’s look at the specs to help determine whether adding a Tesla Powerwall 3 to your solar installation is a wise decision.
How Much Power Does It Store?
The Tesla Powerwall 3 is about the size of a large breaker box and can be installed in-line between your solar panels and your home’s power system. Like the Powerwall + and Powerwall 2, the Tesla Powerwall 3 can store 13.5 kilowatt hours (kWh) of energy per fully charged powerwall.
It does represent an upgrade in power output, now capable of providing 11.5 kW compared to the 5kW of the Powerwall 2. This allows you to power more appliances at once, but will also drain your Powerwall faster if the full output is used.
How Many Powerwalls Do You Need?
If you want to power your entire home with solar energy during a power outage or at night, you will need more than one Tesla Powerwall 3. The Powerwall 3 can stack four batteries per installation. One or two batteries can power your lights, fridge and television for 7-12 hours. However, it will take six or more Powerwalls (averaging $70,000+) to power your entire home at once during an outage.
Price Per kWh Compared With Other Solar Batteries
While the Tesla Powerwall 3 is high in price, it does compare well to other solar batteries in terms of price for both kWh, capacity and output potential. The Powerwall 3 offers approximately $870 per kwH while the Enphase IQ 5P, Panasonic EverVolt Home Battery and sonnenCore+ 10 solar batteries cost between $1,200 to $1,600 per kWh and all have significantly lower output potential at a similar battery size.
