Sonny with his Essential Solar Installer Tesla Powerwall Battery
"We've had both a Tesla battery (with blackout protection) and a supporting solar array installed by Essential Solar. On both occasions, always professional, courteous, protective of our property and left everything immaculate. Dusan in particular was patient and effective in leading us oldies through the performance and operating processes of the new system. Away from the site, Jessica is so professional, if something needs to be done she will get it done, just terrific.

Recommend Essential Solar. Without hesitation."

Powerwall FAQs

We've collated responses to the most common questions we receive from customers contemplating the installation of Tesla batteries. However, as all households are unique, to guarantee you select the best solution that provides a long-term return, we recommend speaking to a member of our team.

How much is a Tesla Powerwall?

A Powerwall Battery is a premium product, priced accordingly. Powerwall pricing surged significantly in 2022 due to high demand and limited supply, but has since reverted to earlier levels. In 2024, the cost of a standalone Powerwall 2, including installation by a reputable installer, is expected to be around $19,000. However, your price will vary based on numerous factors, including the complexities of the installation. For an accurate cost to install a Powerwall Battery at your home, contact our team of solar battery specialists.

Will Powerwall work with my existing solar system?

Tesla batteries are engineered for compatibility with a wide range of solar inverters and panel systems. Nonetheless, compatibility can depend on the specific make and model of your existing equipment, making a professional assessment crucial for seamless integration. As an AC-coupled battery storage system, the Powerwall is particularly beneficial for integration with existing solar installations or when adding battery storage retrospectively. Its inverter is responsible for converting the DC electricity stored in the battery into AC electricity, thereby enabling it to power your home efficiently.

Can I install multiple Tesla batteries?

The Powerwall 2 boasts a usable capacity of 13.5kWh, sufficient to power most family homes under normal conditions. However, it is possible to connect up to 6 Tesla Powerwall 2 batteries, providing a total usable capacity of 81kWh. Should you require this level of energy storage, it's likely we can offer an alternative solution better tailored to your needs.

How long will installation take?

The installation time for a Tesla Powerwall can vary depending on several factors, including the complexity of your home's electrical system, the specific requirements of the installation site, and whether additional electrical upgrades are needed. On average, the installation process can take anywhere from a few hours to a full day.

It's essential to have a site assessment conducted by a member of our team before the installation. This assessment will provide a clearer estimate of the time required based on your home's specific needs and the installation's complexity.

How long will a Tesla backup power my home for?

The duration a Tesla Powerwall 2 can power your home during an outage depends on several factors, including the amount of energy your household consumes, and whether your solar panels are generating power during the outage.

A single Tesla Powerwall has a usable energy storage capacity of 13.5 kWh. The length of time it can power your home is determined by dividing this capacity by your home's hourly energy consumption. For example, if your home uses energy at a rate of 2 kW per hour, a fully charged Powerwall could theoretically power your home for about 6.75 hours (13.5 kWh / 2 kW = 6.75 hours).

However, this is a simplified calculation. Real-world factors such as the efficiency of the system, energy consumption variations throughout the day, and the potential for solar generation to recharge the Powerwall during daylight hours can all affect the actual duration.

What type of battery chemistry does Powerwall use?

The Tesla Powerwall uses lithium-ion battery chemistry, specifically lithium nickel manganese cobalt oxide (NMC). This type of battery chemistry is chosen for its high energy density and long cycle life, making it suitable for residential energy storage applications. Lithium-ion batteries are widely used in various applications, from electric vehicles to portable electronics, due to their efficiency, reliability, and performance. The NMC chemistry in the Powerwall is designed to provide a balance between energy capacity, safety, and longevity, offering homeowners a dependable and effective solution for storing electrical energy.

Where can I install a Powerwall?

The Tesla Powerwall can be mounted on a wall or placed on the floor, indoors or outdoors, in a location protected from harsh weather and direct sunlight. It's best situated near your electrical switchboard and solar inverter for straightforward connections and in an area accessible for maintenance. Optimal placement aims to avoid extreme temperatures to preserve efficiency and lifespan.

Compliance with AS/NZS 5139 standards, which dictate solar battery installation and safety, is crucial. This includes considerations for fire safety, clearance from windows, doors, and pathways, and protection from impacts, such as from a vehicle in a garage. Employing a certified installer is essential for ensuring safety, adherence to regulations, and optimal system performance.
