WHAT THE TESLA POWERWALL 3 CAN BACK UP
Your Tesla Powerwall 3 can act as a whole home backup at night or in the event of a grid outage. How much and how long your Powerwall 3 can backup you home depends on how many batteries you install and how much usage you are trying to back up. The more major appliances you try to run on your battery, the less you’ll be able to backup the rest of your home before recharging.
In general, though, your Tesla Powerwall 3 will back up both 120 V loads (these are lights, plugs, small appliances, etc.) and 240 V loads (this includes air conditioners, electric cooking ranges, well pumps, EV charging, electric dryers, electric water heaters, etc.)
Talking with one of our non-commissioned designers will give you a clear idea of what to expect from home solar and a Tesla Powerwall 3.
