While many may already be aware of the money-saving benefits of solar panels and backup batteries, fewer seem to know just how well the clean energy upgrades can protect your home from power outages. One homeowner took to TikTok to share how long their Tesla Powerwalls can power their appliances during a blackout. 

In the video, the homeowner disconnects their home from the grid and relies entirely on their Powerwalls to test how much energy they can provide.

@jeremyjudkins2 I cant believe the Tesla Powerwalls lasted that long. They were able to power nearly everything in the entire house at once. #tesla #teslasolar #teslapowerwalls ♬ original sound - Jeremy Judkins

"Let's push these Tesla Powerwalls to their absolute limit," video creator Jeremy Judkins (@Jeremyjudkins2) challenges.

After fully cutting off the grid power, Judkins explains that his solar panels are providing more than enough energy to keep his home batteries full and all of his lights on. "We can do some torture tests to it right now," Judkins says.

To demonstrate how much energy his system can generate and store, Judkins ran several high-demand appliances at once, pushing the setup to the edge. It took running the air conditioning, two electric stove burners, a water heater, an oven, home lighting, and an air fryer simultaneously before the Powerwalls began to struggle.
