Installing fast DC charging at home has gotten complicated with all the misinformation flying around. As someone who installs EV charging systems professionally, I learned everything there is to know about what’s actually possible at residential properties. Today, I’ll share it all with you.
The Short Answer: Probably Not
Probably should have led with this section, honestly — DC fast chargers are designed for commercial installations, not homes. The electrical requirements and costs make them impractical for residential use.
Why DC Fast Charging Doesn’t Work at Home
Power Requirements
That’s what makes DC fast charging endearing to road-trippers but impossible at home — even a “small” 50kW DC charger requires more power than most homes’ entire electrical service. You’d need commercial three-phase power, which residential areas don’t typically provide.
Cost
DC fast chargers cost $30,000-$100,000+ for equipment alone. Installation, electrical upgrades, and utility coordination add more. No residential application justifies this investment.
What You Should Install Instead
Level 2 charging (240V, 7-11kW) handles home charging needs perfectly. Overnight charging replenishes typical daily driving. The equipment costs under $1,000 and installation runs $500-$2,000 for most homes.
Save DC fast charging for road trips at commercial stations. Home Level 2 charging handles everything else.
