The Tesla Powerwall is a home battery system designed to store excess solar energy generated by your system. The majority of solar energy is generated during the day, when demand is low. The Powerwall stores the solar energy produced during the day for later use.
The Powerwall uses a lithium nickel-manganese-cobalt (NMC) cell chemistry. The unit features an integrated battery management system (BMS), liquid thermal management, and inverter charger.
The Tesla App enables monitoring of the solar system performance and has different operating modes. These modes allow you to control how and when you use and save energy:
In this mode you can power your home with renewable energy, storing excess solar power that you can use later when the sun is not shining.
In Backup Power mode, you can choose to have the Powerwall simply serve as an emergency backup battery in the event of a power outage.
The Time-Based Control mode is useful when utilities charge different rates depending on the time of the day. Your Powerwall will automatically charge the battery when electricity is cheapest and discharge it when electricity is most expensive, saving you money on your utility bills.
Automatically charges the Powerwall in the event of a major storm or blackout.
The Tesla Powerwall is one of the most popular options on the market that is compatible with almost every solar system. It offers a great storage capacity, incredible warranty and a unique liquid-cooling technology. Feel free to contact us to learn more about the Tesla Powerwall batteries’ advantages and pricing!
It's hard to say how long it will take to charge a Powerwall with solar. It will depend on weather, sun exposure, temperature. On average, an estimated period required for a Powerwall to charge under perfect conditions with no load and 7.6 kW of solar power is 2 hours.
A Powerwall can deliver up to 21 amps, that should be enough to cover your basic energy needs. If you need to power larger appliances you can stack Powerwalls together. In order to decide how many Powerwalls you will need you should analyze your energy consumption and decide what you're expecting to get out of your storage system.
Powerwall can be installed indoors and outdoors, it is not affected by high or low temperatures due to its liquid-cooling technologies. However, you should still avoid installing it in direct sunlight, in areas with sustained extreme temperatures and near water sources. You should also keep it clear from fallen leaves and snow in order to maintain proper ventilation.
Yes, it can be added to your existing solar system. It is known that Powerwall is compatible with solar inverters from SMA, SolarEdge, Fronius, Enphase micro inverter, Delta and ABB.
