If they don’t do so, many solar panel owners will eventually look into solar batteries to supplement their solar systems. You are likely one of these people if you found this article.
Are you looking for a solar battery? Do you want to know how many Tesla Powerwalls you need for your home or business? In short — it depends.
Many factors influence the number of Powerwalls you will need. Consider your household’s average energy consumption and the amount of needed stored electricity.
CONSIDER YOUR HOUSEHOLD SIZE
The average U.S. house size was approximately 2,500 sq. feet as of 2022—meanwhile, a household’s nighttime and temporarily in the case of an power cut.
Let’s suppose there is a blackout like the one that Winter Storm Uri created in Texas in 2021. You need power to keep your lights on and appliances running until the grid comes back up.
A Tesla Powerwall, based on average household consumption, would be capable of keeping the lights on for a family with four to six people during a power cut. This is in addition to the time it takes to turn off the electricity at night and when the demand for electricity is highest. When fully charged, a Tesla Powerwall can provide 13.5 kWh per day. This will allow you to keep your lights on, as well as the TV, refrigerator, and other essential household appliances, such microwaves, working. A Powerwall will not supply power if its charging state reaches 10%. Powerwall owners must ensure that they have 12 kWh of energy in case of an outage.
However, Powerwalls cannot guarantee that you will be completely off-grid.
The number of Powerwalls, the amount of energy you use each day, and how long you keep a Powerwall running without charging it will determine whether you need backup for your entire home.
Please note. If your source of power is not from the grid, you will likely need more than one Powerwall in order to keep power running during outages.
WHAT DOES A WHOLE-HOME BACKUP SYSTEM NEED?
Let’s now look at some additional energy requirements that could put you over the daily average power consumption. This will help you decide if a whole-home backup is feasible.
Let’s suppose your family needs to be able power an air conditioner. Also, you have to supply your basic energy (think lighting and fridge) and major appliances (like a washer and dryer, and Tesla charger to charge an electric car).
At least two Powerwalls are necessary. Two Powerwalls will be sufficient to support both essential and non-essential energy loads.
A whole-home backup won’t work, however. How much energy you use and how long your Powerwalls are unplugged will impact how long you can keep them charged.
All your 120- and 240-volt appliances can be connected to the Powerwall via one circuit. This provides whole-home backup. To conserve power, the user must turn off all 240-volt appliances manually.
