The Tesla Powerwall 3 Is Here!!

The Tesla Powerwall 3 has arrived! We will examine its benefits, limitations, and how it compares to its predecessors, helping you decide if waiting for the Powerwall 3 is the right choice for you.

8MSolar, a Tesla Powerwall Certified Premier Installer, has ample experience installing Powerwalls in North Carolina and Virginia. With the evolving solar energy market and Duke Energy’s PowerPair Solar and Battery Rebate, the relevance of battery storage is on the rise, offering more savings opportunities.

Choosing the right battery storage isn’t just about the latest tech. It involves aligning with your energy goals and lifestyle. We’ll provide insights on the Powerwall 3, comparing it with the reliable Powerwall 2.

Key Upgrades in the Tesla Powerwall 3

Simplified Installation: 57 pounds lighter than the Powerwall 2 Plus, the Powerwall 3 makes installation easier, benefiting both users and installers.

Enhanced Continuous Power: The Powerwall 3 delivers 20-30% more continuous power than the Tesla Powerwall 2 Plus.

Increased Panel Capacity: It can connect up to 35 panels (14kW) on a single inverter, a significant improvement for larger solar systems.

What Can a Single Powerwall 3 Backup?

As noted earlier, a single Powerwall 3 is capable of powering a wide range of household equipment. It can effectively handle most AC/heat pumps, wells, pool equipment, EV chargers, water heaters, and laundry appliances.

The central part of a home energy storage system contains two main aspects: the length of time it can provide power during an outage and its surge capacity. The Powerwall 3 has enhanced its surge capacity, meaning it can support larger energy-consuming devices. However, this improvement does not extend the duration of power supply. Therefore, while it can power more devices during an outage, the duration for which these devices can run may be limited unless energy usage is strategically managed.

Considerations Before Purchasing the Powerwall 3

The upcoming Tesla Powerwall 3 brings exciting features, but it’s important to weigh certain factors before deciding to wait for its release. Here are some factors to consider:

Unchanged Energy Storage Capacity: Despite various improvements, the Powerwall 3 maintains the same energy storage capacity as the Powerwall 2 and Plus models.

Potential for Shorter Backup Duration: The increased energy withdrawal rate of the Powerwall 3 could mean reduced backup duration during power outages.

Consistent Warranty Term: The warranty for the Powerwall 3 remains the same as that of the Powerwall 2 and Plus, spanning 10 years.

The Cost of the Powerwall 3

For context, before installation, the Tesla Powerwall 3 cost ranges from $9,000 to $13,000 (hardware plus installation labor) depending on the complexity of the installation, and the solar panel system connected to the battery. A Tesla Powerwall installation is usually priced between $3,000 and $8,000 depending on the number of Powerwalls to install. The price for each additional unit or when bundled with a solar system purchase is about $8,400 to $11,600.

Deciding on a Powerwall 3 or Other Powerwalls

When it comes to energy storage technology, timing is a crucial consideration. With the current 30% Solar Tax Credit and rising electricity rates in North Carolina, there might be advantages to not delaying your decision.

However, the Powerwall 3 could be the better choice in specific scenarios:

For New Builds: Those building new homes with energy systems around 15kW might find the Powerwall 3 more appropriate. It offers the option of using a single Powerwall 3 instead of two Powerwall Plus units, potentially saving on inverter costs, albeit with slightly less battery storage.

Power Interruptions: In cities where power disruptions are short but frequent, the Powerwall 3 can provide seamless energy continuity. However, for areas prone to prolonged outages, the Powerwall Plus, with its larger storage capacity, may be a more fitting choice.

Future of Powerwall 2 and 2+ Amid Powerwall 3 Release

As Tesla gears up for the Powerwall 3 launch, there’s been curiosity about the fate of the Powerwall 2 and 2 Plus models. The good news is, they are not being discontinued! The Powerwall 3 is an addition to Tesla’s lineup, not a replacement. Both Powerwall 2 and 2 Plus will remain available, continuing to serve as effective solutions depending on individual energy needs. Remember, the latest model isn’t always the most suitable for everyone let us help you decided what is best for your situation.
