Check the Database of State Incentives for Renewables & Efficiency (DSIRE) for local incentives. Many states also offer tax credits or rebates for green equipment. The credit decreases to 26% in 2033 and 22% in 2034. Tesla Powerwalls are eligible for a 30% Federal Tax Credit for installations before 2033. Preconditioning – turns on and heats the Powerwall to improve operation and charging performance when temperatures are below freezing Self-Consumption Only – produces only enough energy required to power the home, not releasing energy to the grid until the system receives Permission to Operate (PTO) from the utility company Time-Based Control – maximizes savings by collecting and storing energy during off-peak hours when utility rates are lowerĮnergy Exports – sends energy back to the grid to earn credits when utility rates are high Self-Powered – stores solar energy not used during the day to power the home at night Tesla Powerwall operating modes and compatibilityĪ Tesla Powerwall features several performance modes with unique settings and features that can be configured through the mobile app:īackup Reserve – reserves a portion of the stored energy for use during a grid outage Tesla only guarantees Powerwalls purchased directly from them or a certified installer. The Powerwall is covered by a 10-year limited warranty against defects, failure, and premature battery capacity loss. Peak power covers the initial surge required for major appliances when an outage begins.Ĭontinuous power is the amount of power the battery can steadily output until depleted.Ī Tesla Powerwall battery's lifespan is 10 to 20 years on average, depending on usage. Peak power is the amount of power the battery can push out for up to 10 seconds. The Powerwall provides 5 kW of continuous power and 7 kW of peak power, while the Powerwall+ provides 5.8 kW of continuous power and 7.6 kW of peak power. Homeowners can extend the backup time by using the Tesla app to prioritize essential appliances, like the refrigerator and LED lights. The average home uses 25 to 30 kWh of energy per day, requiring a minimum of two Powerwalls to provide whole-house power for one day. Tesla guarantees the Powerwall's battery will retain at least 70% of its original capacity at 10 years after installation. The Tesla Powerwall has a 13.5 kWh usable energy capacity. NMC batteries are known for their increased safety and high energy density-the ability to store a large amount of energy relative to the physical space they take up. The Powerwall features an NMC lithium-ion battery. DoD is the percentage of stored energy the battery can discharge relative to its total capacity. The Powerwall can output 9 kWh for every 10 kWh of electricity stored.ĭepth of discharge – The Powerwall's depth of discharge is 100%. Round-trip efficiency is the percentage of energy stored in the battery that may be retrieved later. Round-trip efficiency – The Powerwall has a round-trip efficiency of 90%. Tesla Powerwall 2 and Powerwall+ specs FeatureĪ Tesla Powerwall battery's storage efficiency is measured in round-trip efficiency and depth of discharge (DoD):
