Tesla Powerwall frequently asked questions

General

Can Powerwall supply my entire home with power in the case of a blackout?

Yes, Powerwall is designed to power your entire home in the case of a blackout. The maximum continuous power output from a single Powerwall is 5kW. In the event that your home is using more than 5kW, then the system will shut down and then attempt to restart. During a blackout you may need to limit the use of very high powered appliances like air conditioners to keep your total energy use below 5kW.

Do I need additional hardware?

With Evergen’s fully integrated system, all required hardware is included and contained in the standard installed price. For homes with no existing solar, the major hardware components include solar panels, solar inverter, Tesla Powerwall and the Tesla Powerwall Gateway. For homes with existing solar, you are able to use your existing solar inverter with Tesla Powerwall.

Sometimes after analysing your home, Evergen may recommend additional hardware to optimise your system in certain circumstances. For example, for homes with roof shading issues, Evergen may recommend the addition of micro inverters to enable your solar system to perform better in partial shade.
