how many powerwalls do I need?
The number of Tesla Powerwalls you need depends on your home's energy usage, desired backup duration, and whether you're backing up essential circuits or your entire home. Most homes can start with one Powerwall 3 for essential loads, while two or more are recommended for whole-home backup or powering high-demand appliances. Adding DC expansion units can increase storage without extra inverters. Contact us for an accurate recommendation.
how long will powerwall last in an outage?
A single Tesla Powerwall 3 can power essential appliances for 12 to 24 hours, depending on your energy usage. With solar panels, the Powerwall can recharge during the day, extending backup time significantly. High-demand appliances or EV charging will reduce runtime. For longer outages or whole-home backup, multiple Powerwalls or expansion units may be recommended. To maximise backup time, you can configure the system to support only critical circuits.
How does the Tesla Powerwall 3 integrate with solar panels?
Tesla Powerwall 3 features a built-in solar inverter that allows solar panels to connect directly to the battery for maximum efficiency and a sleek, compact installation. It stores excess solar energy for use at night, during peak times, or in a power outage. With up to 97.5% efficiency, the system ensures you get the most out of your solar setup. Everything is managed in real time through the Tesla app, giving you full control over your energy production and storage.
