Charging that keeps up
Multiphase Electric provides complete residential and commercial EV charging solutions, from planning and electrical design through installation and commissioning.
As a ChargePoint Certified Installer and partner, we install charging solutions for homes, businesses, multifamily properties, and commercial facilities — from single residential chargers to larger EV charging systems.
Every project starts with an evaluation of the existing electrical system and available capacity. When needed, we perform load calculations and determine whether load management, panel modifications, or a service upgrade is required.
Our services include electrical planning, dedicated circuits, panel and service upgrades, load management, equipment installation, and project coordination. As a SPAN Certified Installer, we can also provide smart panel and energy-management solutions.
From initial design through final testing, Multiphase Electric provides one electrical contractor for the complete EV charging project.
What we offer:
- End-to-end EV charging design, installation, and testing
- Solutions for homes, businesses, multifamily, and commercial sites
- Load calculations, panel upgrades, and smart load management
- One electrical contractor for the complete charging project

Why it's simpler
-
Usually no upgrade
We check the capacity you already have first. Smart load management frequently supports reliable charging on the existing service, which is the cheaper way to get there.
-
Full every morning
A dedicated 240V circuit adds 20–30 miles of range an hour, so a normal night on the charger covers a normal day of driving with room left over.
-
Room for the next one
Parking structures, multi-family, and fleet yards are planned as infrastructure, so the second and tenth charger don't mean starting the electrical over.
Capacity checked before a charger is ever quoted.
-
Capacity assessment
We check your existing service capacity and run a load calculation where one is needed, before recommending charger size — no surprises about a required upgrade after the fact.
-
Permit pulled, install scheduled
We pull the electrical permit and book the install. Most installs happen within 1–2 weeks of the quote.
-
Clean install, tested and inspected
Circuit run, charger mounted, output tested under load. We book the inspection in our name, and the signed permit comes back to you.

before you plug in
What drivers want settled before the quote. If yours isn't here, ask — it is a short conversation, not a sales call.
Can you provide a Level 2 EV charger?
Yes. Multiphase Electric LLC can supply the charger, and if you already have one you'd like to use, we can install that for you as well. Either way it is installed to the manufacturer's requirements and current electrical code.
Do I need to upgrade my panel before installing an EV charger?
Not always. Most homes with a 200A panel have room for a 40–50A charger circuit. We evaluate your available capacity as part of every EV charger quote, and where capacity is tight, smart load management through a SPAN panel can often support charging on the service you already have instead of forcing an upgrade.
How long does the install take?
A straightforward garage install typically takes 2–4 hours. Longer runs through attics, crawl spaces, or conduit through finished walls take longer. We'll give you a time range when we quote it.
Do you install Tesla Wall Connectors and other brands?
Yes — Tesla Wall Connector, or any other NEMA-compliant unit. If you already bought a charger, we install it; if you have not, we can supply one.
Do I need a permit to install an EV charger in Oregon?
Yes. An EV charger is a new dedicated circuit, and Oregon requires a permit for it. We pull the permit and schedule the inspection as part of the install.
How much faster is a Level 2 charger than a normal outlet?
A Level 2 charger on a 40–50A circuit adds roughly 20–30 miles of range per hour, so an overnight charge covers almost any commute. A standard 120V outlet adds only a few miles per hour, which is why most drivers outgrow it.
Can you install charging for a business or a fleet?
Yes. We install in parking structures, multi-family buildings, and commercial fleet yards, including load management so several chargers can share one service without forcing an upgrade.
