Powerwall 3 is literally built for brutal winter conditions Tesla’s Heat Mode intelligently warms the battery so it can keep charging and discharging even when outside temperatures fall to -20°C How it works: • Heat Mode automatically warms the battery cells when needed • At -20°C ambient, it can maintain a minimum internal cell temperature of 0°C • It typically uses only ~200 Wh to prepare the battery for charging from solar • Works automatically…no manual heating setup needed • Powerwall 3 is rated to operate from -20°C to 50°C • Designed for both indoor and outdoor installation So even on the coldest winter days, Powerwall can keep storing solar, powering the home and staying ready for an outage A home battery that basically keeps itself warm so it can keep working

2 Powerwall modes now decide when your Tesla charges. Update 26.34 links a Gen 3 Wall Connector to Powerwall: Self-Powered = Charge on Solar (extra solar goes to the car) Savings = Low-Cost Charging (cheapest hours on your rate plan) Which mode is yours set to?

2 Powerwall 3s, side by side on one North Potomac wall. Add a Gateway 3 and solar feeding in (471 W on the app at commissioning), and this home is set up for backup power when the grid goes down. @TeslaEnergy #Powerwall# American Home Contractors | MD & VA

Four powerwall 3s ready to be installed on Wednesday!! @teslaenergy I really enjoyed meeting you at the merch booth @theXtakeover and I told you I would post so much when the time came. Let's go!!

Tesla Powerwalls just powered the largest residential distributed power plant dispatch ever recorded During extreme heat in California, more than 140,000 home batteries were dispatched for 3 hours, reaching 580+ MW of peak power back into the grid Tesla Powerwalls absolutely dominated the event: • ~110,000 Powerwalls participated • 517 MW came from Powerwalls alone • Another 63 MW came from 30,000+ other home batteries • Tesla Powerwalls delivered nearly 90% of the total peak output • 580+ MW total peak output • Enough to power every household in Sacramento County during peak hours The scale is insane More than 100,000 Tesla Powerwalls sitting inside people’s homes effectively operated as one massive distributed power plant exactly when California needed it And there was even more capacity available Tesla and Sunrun reported that their fleets had the ability to deliver more than 720 MW if the following night’s Southern California dispatch had happened at the same time This is what Tesla’s vision for distributed energy starts to look like at real scale

Tesla Powerwalls just acted like a 500+ MW power plant.....without Tesla building a new power plant Around 69,000 Powerwall owners across California simultaneously sent more than 500 MW back to the grid during the heatwave this is now a single giant battery facility Thousands of batteries already sitting inside people’s homes, coordinated by Tesla software and acting together like one massive distributed power station When electricity demand spikes, Powerwalls can discharge instantly and help stabilize the grid This is where Tesla Energy becomes much bigger than selling batteries Hardware distributed everywhere Software coordinating everything 69,000 homes just acted as grid infrastructure
