Lancaster Powerwall Installer

Belmont Solar is a certified Tesla Installer! We sell and install the new Powerwall 3, a compact home battery backup that stores energy from your solar panel system or the power grid. A home battery backup is used to power essential appliances during a power outage or to power your home during the night while your solar system is not generating electricity. The Powerwall 3 has multiple customizable power modes to optimize stored energy for outage protection, electric bill savings, and more. Let’s take a look at the new and improved Powerwall system!

Why Buy a Powerwall?

The Powerwall 3 is the latest version of Tesla’s home battery backup system. It features an integrated solar inverter and can be installed with a solar system or as a battery backup, removing the need for a backup generator. Unlike other batteries with separate inverters, the Powerwall 3 can power your home in one integrated unit. It is scalable, allowing you to expand your battery backup storage anytime. Here are the primary uses of the Powerwall.

Store and Use Energy

Powerwalls are often used with either a Hybrid or Off-Grid solar system. You can store excess energy produced during the day and use it at night. However, you do not need a solar system to use a Powerwall. A Powerwall can function as a home battery backup instead of a backup generator to protect against power outages. Visit our Home Battery Backup blog to learn more about protecting yourself against power outages.

Save Money

A solar system generates free electricity using the power of the sun. A Powerwall allows you to store and use more free energy from the sun., however, a it can help you save money, even without installing a solar system! Electricity pricing is often cheaper late at night or early in the morning and most expensive from 2 PM – 9 PM. You can charge your battery during the off-peak hours at a lower cost and use that energy during peak hours. By using energy stored from off-peak hours, you can reduce your energy bill over time. If you live in an area where the Tesla Virtual Power Plant is available, you can sell the energy stored in your battery backup. Tesla’s VPP program aggregates the energy stored in Powerwalls across thousands of homes to provide a network of on-demand energy that supports your local grid during peak hours. You can sign up for the Tesla VPP program through the Tesla app.

Powerwall 3 VS Powerwall 2

Unlike the Powerwall 2, the Powerwall 3 has an integrated inverter, increased capacity, and is flood resistant up to 2′. Here are the specs of both systems so you can see the upgrades.

Tesla Powershare

With the release of the Cybertruck, Tesla has introduced its Powershare technology. Cybertruck owners can power their electronic devices, vehicles, or homes during a power outage and expand their current Powerwall storage capacity. Here are the capabilities of Powershare.


Home Backup

One of Powershare’s most practical applications is providing backup power to your home during an outage. Your Cybertruck can automatically detect an outage and start providing power within one minute without the noise, emissions, or maintenance that comes with a backup generator. A Cybertruck can provide 11.5KW of power, the same as the Powerwall 3, making it a reliable and efficient backup power source for your home.

If you want to use your Cybertruck as a home battery backup, contact us, and we will install the hardware needed.

Power on the Go

The Cybertruck has two 120V outlets in the cabin plus one 240V and two 120V outlets in the cargo bed. With Powershare, you can power electric devices or tools.

Charge Other EVs

Plugging into the 240V cargo bed outlet allows you to charge other electric vehicles with up to 9.6 kW of power.
