We are a Certified Tesla Powerwall Installer


Tesla Powerwall

Next Phase Electric is a Tesla Powerwall Certified Installer, which means we offer a customized battery solution that enables you to access the free, abundant power of the sun and reduces your reliance on fossil fuels.

During the day, the sun shines on your solar panels, charging your battery. At night, your home draws electricity from your battery, powering your home with clean, sustainable energy 24/7.

Why Tesla Powerwall?

  • Reliable, clean, safe, quiet, and environmentally friendly
  • Can be installed anywhere in your home or business
  • Cost-effective
  • Increased energy savings and peace of mind
  • Increasing self-consumption of solar power generation – Powerwall can store surplus solar energy during daylight hours and use that energy later when the sun is not shining.
  • Load shifting – Powerwall can charge during low rate periods when demand for electricity is lower and discharge during more expensive rate periods when electricity demand is higher.
  • Back-up power – Assures power in the event of a grid outage.

What is a Home Battery?

A home battery acts like a barrier between your home and the power grid. It plugs right into your current electrical system to optimize daily energy use and to provide backup power during a grid failure. It does this by taking in power from the grid or your solar panels and then strategically deploying it on your house.

Home batteries have been around for decades. But like the cell phone before the smart phone, home batteries used to be bulky, expensive, inconvenient, and limited in functionality. At Swell, we specialize in the new generation of smart, lithium-ion home batteries.

Smart home batteries use the same advanced lithium ion battery cells that power electric cars like the Tesla. We work with the best battery technology companies in the world, providing compact, automated, cloud-connected home battery systems that require no maintenance and last over 10 years.

How does it work?

Tesla Powerwall and the Grid

  1. The Grid: The grid is the largest machine on Earth. Just three grids comprise the entire US power system, interconnecting thousands of power plants and millions of miles of transmission and distribution lines that deliver power to end users, like you.
  2. Main Distribution Panel: Power from the grid enters your home through a single set of wires. The main distribution panel splits power from the grid and sends it along circuits to the rooms and appliances in your house. After installing a home battery, only certain larger loads remain connected directly to the main panel. Anything connected to the main panel (which includes everything in a home without a battery), is susceptible to a power outage.
  3. Home Battery System: A home battery system acts as a buffer between the grid and your home. It charges from solar panels or the grid. In an outage, the battery instantaneously disconnects from the main panel and the rest of the electrical grid, creating a self-sustaining, personal grid that includes solar panels and the important things in the home. When the sun goes down, a home battery can power your home with stored solar energy, all night long.
  4. Solar System: Photovoltaic solar panels convert sunlight into electricity. Because solar panels generate direct current (DC) electricity, an inverter is required to transform solar electricity into alternating current (AC), which is the type of electricity used in your home.
  5. Critical Loads Panel: During installation of a home battery, a certified electrician installs a critical loads panel, which has the same function as the main distribution panel. The home battery powers the critical loads panel, which sends electricity to all of the important rooms and appliances in your home.
