Plug-in chargers can be the easiest type of station to install. Many electric vehicle (EV) drivers already have an outlet they can use in their garage. Residential 240-volt (V) plugs, sometimes called dryer outlets, are higher powered and can charge your car quicker than standard 120V outlets. Plug-in charging stations that use a 240V outlet are also specifically designed for occasional relocation, like during a road trip or moving from home to home. Residential 120V plugs, sometimes called household outlets, offer much slower charging but work in a pinch.
Match your outlet with your plug type
You might be surprised to learn there is no universal standard design for 240V plugs (similar to any home appliance). Depending on the outlet you already have in your garage or you’re planning on having installed, Enphase offers a variety of these plug types to fit your needs.
Please note that all three of these outlets require a dedicated circuit rated for the amperage (A) of the charging station.

I need help deciding
If you don’t see your outlet below, you’re not sure which one you have, or you think you might need a new outlet installed, an electrician can help you determine the voltage as well as breaker capacity.

Safety first
Before plugging in EV charging equipment, be sure to follow recommended safety guidelines. For personal safety, the circuit breaker MUST be turned off prior to plugging in and/or unplugging 240V appliances (including charging stations).
One of the main functions of a charging station is to ensure correct grounding connections, transferring building power to the onboard charger. EVs are grounded through the charging cable and charging station.
