Commercial EV chargers: workplace and customer infrastructure.
Commercial EV charging infrastructure — Level 2 chargers for workplace or customer charging, networked stations with management software, sometimes DC fast charging for higher throughput.

Commercial EV charging electrical: Level 2 chargers (240V or 208V, typically 32-40A per port) for workplace and customer use; DC fast chargers (480V 3-phase, 100-350A per port) for high-throughput applications. Networked stations enable usage management and billing. Panel coordination for multi-station installations: load management software reduces simultaneous demand vs full nameplate sum. Marin commercial EV installations growing significantly post-2024.
01Commercial EV charger types.
Level 2 charging (240V or 208V AC) is the most common commercial deployment. Provides 25-35 miles of range per hour of charging — sufficient for workplace charging during business hours or customer charging during retail visits. Networked stations (ChargePoint, EV Connect, Blink, Tesla Wall Connector with network) enable usage tracking, billing, and load management. Typical workplace install: 4-12 chargers at office building or campus.
DC fast charging (DCFC, Level 3) provides 100-200+ miles of range per hour but requires high-amperage 3-phase electrical service (often 480V) and more complex equipment. DCFC installation cost significantly higher; typically only at locations serving transient charging (gas station-style, retail with high turnover) rather than dwell-time charging (offices, hotels).
02Three considerations for commercial EV charger projects.
Panel and service capacity
4 ports × 40A = 160A potential demand — significant load addition. Existing panel may need upgrade to accommodate. Service entrance may need upgrade for larger installations. Load study during planning identifies capacity needs.
Load management software
Networked chargers can coordinate demand — instead of 4 chargers × 40A simultaneous (160A peak), system distributes available power across active sessions (4 chargers × 20A average if all charging simultaneously). Reduces infrastructure cost meaningfully for larger installations.
Future-proofing
Electrical infrastructure (panel space, conduit routing, conductor sizing) for future EV expansion costs little incremental during initial install; expensive to retrofit later. Plan for 2-3x current EV charger count when sizing initial infrastructure.
03Common Marin commercial EV scenarios.
Workplace charging (4-8 chargers): office building or campus serving employees. Networked Level 2 chargers with billing for usage. Panel upgrade often required. Scope $25,000-$80,000 typical. Customer charging at retail (2-4 chargers): grocery, retail center, restaurant providing customer service. Marketed as amenity; often combined with utility rebates. Scope $12,000-$35,000.
Multi-tenant residential charging (Marin properties with commercial HOA or multi-family): shared charging infrastructure. Allocation challenges (whose electricity?) addressed through networked billing. Scope varies significantly with property scale. EV charging for hotel/hospitality: customer amenity charging during stays. Typical scope 4-12 chargers $25,000-$90,000.
Common questions.
Do I need to upgrade my panel for EV chargers?
Depends on current panel capacity and charger count. Single Level 2 charger: usually fits existing capacity. Multiple chargers (4+): often requires panel upgrade or sub-panel addition. Load management software reduces capacity requirement. We assess during planning.
What rebates are available for commercial EV?
PG&E offers commercial EV rebates through their EV charger incentive programs. BayREN adds Bay Area incentives. State of California offers commercial EV charging grants for qualifying installations. Combined incentives can cover 30-60% of installation cost. We coordinate rebate applications as project scope.
Should I install DC fast charging?
For most commercial Marin locations: no — Level 2 charging serves typical use cases (workplace, retail dwell-time). DC fast charging justified for high-throughput locations (gas station model, transit hubs, fleet operations). Cost premium significant ($150,000+ per DCFC port). Most commercial Marin EV is Level 2.
How do you handle pricing — flat fee or hourly?
Both, depending on scope. Routine service calls and predictable scope (panel replacement, EV charger install, transfer switch install, fixture replacement) are flat-fee quoted up front. Diagnostic visits and emergency scope are hourly because we don't know what we'll find. Either way, you get a written quote before work starts on anything significant, and we don't proceed beyond the quote without your sign-off.
How quickly can you schedule?
Depends on scope and season. Emergency dispatch: same-day across Marin County (1-3 hours business hours, 1-4 hours after-hours). Same-day standard service: 3-6 hours from call when capacity allows; otherwise next business day. Scheduled service work: 1-3 weeks typical. Larger projects requiring permits and PG&E coordination: 4-12 weeks depending on scope. We're upfront about timeline at the quote stage.
What warranty do you offer on work?
Our standard residential warranty: 2 years on labor, manufacturer warranty on parts (varies by product — typically 1-10 years). Major installs (panels, generators, EV chargers) often have longer manufacturer warranties (5-10 years). If there's an issue with our work in the warranty period, we come back and fix it at no cost. We also stand behind work past warranty — repeat customers and referrals matter more than a transactional fix.
Are you licensed and insured?
Yes. California State License Board C-10 Electrical Contractor #989290, in good standing. Carry general liability insurance and workers' compensation insurance as required by California law. Bondable on projects requiring it. Happy to provide proof of insurance to clients or property managers on request. License lookup: cslb.ca.gov.
