A Powerwall Plus inverter can generally support 9-10kW of solar for a site with great solar exposure and can be installed with up to 2 Powerwall batteries stacked together. Each Powerwall battery holds 13.5 kWh of backup storage capacity. With a single battery, you’d be able to power some lights, wall outlets, a refrigerator, and a few smaller appliances.  Learn more about how many Powerwalls you need to backup different energy loads in your home →
