Frequently Asked Questions

How many Tesla Powerwall batteries do I need?

The number of Tesla Powerwall batteries you need depends on various factors such as your energy consumption, desired backup capacity, and whether you have solar panels. A single Powerwall 3 typically provides 13.5 kWh of energy storage. For a more accurate assessment, please get in touch.

Will a Tesla Powerwall work WITH solar panels?

Yes, the Tesla Powerwall 3 can work without solar panels. It can be charged from the grid during off-peak hours when electricity rates are lower and can provide backup power during outages or peak demand periods.

Can a Powerwall 3 be retrofitted to an existing solar panel system?

Yes, a Tesla Powerwall can often be retrofitted to an existing solar panel system. However, compatibility may depend on the age and type of your existing system. It's recommended to get in contact with us to assess the compatibility of retrofitting a Powerwall to your specific solar setup.

Will a Telsa Powerwall work during a power cut?

Yes, one of the primary functions of the Tesla Powerwall is to provide backup power during a power outage. It can automatically detect an outage and switch to battery power, ensuring a continuous power supply to critical appliances and devices.

How long does a Tesla Powerwall charge last?

The duration a Tesla Powerwall charge lasts depends on your energy consumption and the number of Powerwall 3s you have. A single fully charged Powerwall provides 13.5 kWh of energy. If your energy usage is consistent, you can estimate the duration by dividing the Powerwall 3 capacity by your average daily consumption. For example, if your daily consumption is 10 kWh, a single fully charged Powerwall could potentially provide around 1.35 days of backup power. Keep in mind that this is a rough estimate, and actual performance may vary based on specific circumstances.

What is the Tesla Gateway and why do I need one?

All Powerwall 3 installations must have a Tesla Gateway. A Gateway allows your home to go 'off-Grid', meaning your Powerwall 3 can power your home in the event of a powercut.
