Claude There you go, it’s done! After years of waiting, the Tesla Powerwall officially lands on French soil. But not as a gadget reserved for home automation enthusiasts. No, the Powerwall 3 arrives to concretely transform the way we consume, store, and manage electricity at home. Let’s discover it in more detail. A concentrate of technology in the Tesla Powerwall sauce Forget the old idea of the “big battery at the back of the garage.” The Tesla Powerwall 3 is a compact energy hub, equally at home on your living room wall (design option: smooth tempered glass, if you like showing off your high-tech toys to your guests) or at the back of a garden shed. It weighs 130 kg with dimensions of 1105 mm x 609 mm x 193 mm, and can be mounted on the wall or on the floor, depending on the mood of the moment. What makes it unique is this “all-in-one” approach: lithium-ion battery, integrated solar inverter of 11.04 kW, smart management via the Tesla mobile app, and, let’s be bold, the ability to manage the entire house, from the dryer to the hot tub (yes, even during a power outage, the Powerwall takes over quickly). Autonomy, backup… and savings with the Tesla Powerwall The Tesla Powerwall 3 offers enough to make most French households much more autonomous. Each unit provides 13.5 kWh of capacity. In practice, a family of four equipped with 6 kW of photovoltaic panels can store the surplus solar energy from the day to use in the evening, even maintaining power during an outage without losing their smile (or the wifi). With up to four Powerwall units and three expansion modules, the total capacity can reach 94.5 kWh with 44 kW of continuous power. Enough to cover even XXL homes. And if I want to plug in an electric car? No worries! The Powerwall 3 takes care of the excess solar power, recharges your Tesla (if you have one, of course), and ensures that the battery is always ready to go. It can even prioritize usage: fridge, heating, internet box, all remain powered even during a blackout. Savings that put butter on the spinach The figures presented are far from anecdotal. Tesla announces up to €1,010 in savings per year for a house equipped with a Powerwall 3 and the appropriate solar panels. Two key principles for this: the reduction of dependency on the grid (up to -69%!) and self-consumption. The system stores energy during the day and then releases it in the evening or during peak tariff periods. And for those who play with variable rates (peak hours/off-peak hours), the famous “Time-Based Control Mode” allows charging the battery at the most advantageous rate to use it at high rates. After a sunny day, a couple with children can dine under the “stored” sunlight, start a laundry, watch Netflix, and recharge electric bikes, without drawing a watt from the grid. Not bad for the planet and the bill! Tesla Powerwall: Technical specifications and configuration possibilities Here is a small summary table of this long-awaited battery: Feature
