The full electrical scope

Panel upgrades

Battery storage systems

EV charger installations

Residential and commercial battery backup installations sized to your load profile. Integrated with existing solar or grid-tied systems, all code-compliant.

Level 2 residential and commercial Level 3 DC fast-charge installs. Load calculations included — charger, panel, and storage sized together from the start.

200A and 400A service upgrades, sub-panel additions, and full replacements. Every job is permitted and passes final inspection before we close out.

• Residential & commercial

Sized correctly from the first calculation

Willis runs the load management numbers before a single conduit is pulled. The charger, the panel capacity, and any battery system are specified together — not retrofitted around each other.

Commercial properties get the same licensed technician who sized the HVAC load. Residential driveways get a permitted install, not a quick plug-in.

Level 2 home chargers. Level 3 commercial DC fast-charge. Both pulled by Willis, both inspected to code.
