What is 3 Phase Power?

Three phase power is where more power can be brought into a building. Most residential homes use one phase power and will be able to operate reliably. Commercial buildings and larger areas use three phases but residential homes can still upgrade to 3 phases. Single phase draws 240V while 3 phase draws 240V and 415V to a building and allows homes a larger amount and stronger power source.

Why is 3 Phase Power Beneficial?

3 phase upgrades for Tesla and electric vehicles is beneficial in that the home is given a more reliable and powerful power supply. As a result the home can use larger appliances at the same time without the chance of electrical surges occurring more frequently. More power means more appliances can use power and a less chance of the large draw of power causing stress to the system. 

For example, the air conditioner can run while the electric hot water system and also the Tesla charger. When homes are being renovated or more appliances are being installed deciding if 3 phase power is recommended should be considered.

Do I Need 3 Phase Power for My Tesla Charger?

It is not needed for a home to have 3 phase power for it to reliably run electric car chargers. 3 phase upgrades for Tesla and electric vehicles is beneficial though because the car will be able to charge faster and more efficiently. This is because the car overall charges faster because it can safely draw out more power. 

While the car charges, other appliances and systems can be safely used without the fear of overloading the electrical power supply system. Since 3 phase power charges the car faster it will decrease the energy cost, especially if this is mixed with an energy efficient car charger.

Upgrading the power supply to 3 phase simply because an electric vehicle charging station will be installed and for that reason alone it will often not be needed. However, if upgrading to 3 phase will benefit the charger and other systems of the home then t is recommended as it will be more powerful, safe, reliable and efficient.
