Stepwise Tap™ — Fast EV Charging Without a Panel Upgrade

Most homes can add a 48A Level 2 EV charger without an expensive service upgrade. The Stepwise Tap™ is a UL-listed Energy Management System that manages your panel load automatically — giving you fast charging at a fraction of the cost.

A smarter way to add EV charging

Adding a new EV charger often pushes an electrical panel past its limits — which normally means a panel upgrade costing $3,000–$6,000, plus utility delays and added labor.

Stepwise Tap™ eliminates all of that.

The Tap is a smart device that automatically manages your charger’s load. When your home’s usage increases — AC, dryer, oven, hot tub — Stepwise intelligently adjusts the charging so you never overload your panel..

Result:

  • Install 48A fast charging even on “full” panels
  • Charge 2–3× faster than a basic 24A outlet
  • Avoid an expensive panel upgrade
  • Installed cleanly in about 2 hours

 Benefits List

 

  • 2–3× faster charging vs standard 24A outlets
  • Skips the need for a panel upgrade (save $3–$6K)
  • Safe & certified — UL‑listed, USA‑made
  • Future‑proof — supports multiple EVs & future appliances

Stepwise Tap™ vs. Full Panel Upgrade — Which One Do You Need?

Both are safe, code-approved solutions. The right choice depends on your panel's condition, your planned loads, and your long-term goals.

Stepwise Tap™ is likely the right fit when:

  • You're adding an EV charger and your panel is full or nearly full
  • Your panel is in good condition but lacks available capacity
  • You want to avoid the cost of a full panel upgrade
  • Only one major new load is being added
  • Your usage patterns allow for managed, flexible charging

A panel upgrade is likely the right fit when:

  • Your panel is outdated, unsafe, or obsolete (Federal Pacific, Zinsco)
  • You're adding multiple new high-demand systems
  • You're planning significant long-term electrical expansion
  • Your panel has no available breaker space at all
  • Insurance or inspection has flagged the existing panel
