EV Charger Installation on Oʻahu
Why a Licensed Install Matters
An EV charger is likely the biggest electrical load in your house. The National Electrical Code classifies it as a continuous load, which means the wire and breaker must be sized 125% above the charger’s amperage. Skipping that math, or using the wrong wire gauge, is one of the leading causes of residential electrical fires.
We do the load calculation properly. We use torque-rated tools on every connection. We pull every permit. We coordinate inspection. And because we hold the electrical license, we can upgrade your panel in-house if your current service cannot safely handle a charger.

Frequently Asked Questions
Do I Need a Panel Upgrade?
Maybe. If you have 200-amp service, a Level 2 charger usually fits without a service upgrade. If you have 100-amp service, common in older Oʻahu homes, adding an EV charger alongside an AC unit, range, and dryer often exceeds safe capacity. In those cases we have two options:
- Service upgrade to 200 amps. The traditional solution. Works for almost every home.
- Load management (SPAN Smart Panel or similar). A newer option that dynamically balances loads so you can add EV charging without a full panel swap. Faster and often cheaper.
We will walk you through both options and recommend the right one for your home.
How much does an EV charger installation cost on Oʻahu?
A standard Level 2 installation typically runs $1,200 to $2,500 installed, depending on the distance from your panel to the parking spot, the charger model, and whether any electrical upgrades are needed. We will give you a firm number after a quick site assessment.
How long does install take?
Most standard installs take one day. Permitting adds 1 to 2 weeks before that. A panel upgrade adds another 1 to 2 weeks.
Can I just use the outlet that came with my house?
Possibly, for occasional charging. But a standard 120-volt outlet is roughly four to eight times slower than a Level 2 charger, and many dryer-style outlets are not rated for the daily plug-and-unplug cycle of EV charging. A dedicated installation is the safe, fast, and code-compliant answer.
Does Hawaiʻi offer EV charging rebates?
HECO and the State of Hawaiʻi periodically offer rebates and time-of-use rate programs for EV owners. We will tell you which programs you currently qualify for as part of your estimate.
