Level 2 Charging for O'Fallon Homeowners

A Level 2 charger delivers 25–30 miles of range per hour of charging — versus 3–5 miles per hour on a standard 120V outlet. For O'Fallon homeowners with daily commutes across St. Louis County, that means a full charge overnight every night without any planning. As one of Missouri's fastest-growing cities, O'Fallon has a high concentration of newer homes with 200A panels — but growing electrical loads from EVs and home additions are pushing capacity limits.

Does Your O'Fallon Home Need a Panel Upgrade First?

A Level 2 charger needs a dedicated 240V, 50A circuit. Many O'Fallon homes have panel capacity for this without any upgrade. We assess your panel during every estimate — if an upgrade is needed, we'll tell you upfront with full pricing. We handle both the panel work and charger installation in a single visit where possible.
