Electrifying South Florida’s Commercial Real Estate

The transition to electric mobility is accelerating, and South Florida is at the epicenter of this shift. For commercial property owners, retail centers, and logistics fleet managers, offering robust Electric Vehicle (EV) charging is no longer a luxury amenity—it is an operational requirement.

Deploying Commercial EV Charging Infrastructure requires far more technical foresight than simply bolting chargers to a concrete wall. It is an exercise in high-capacity energy management, utility coordination, and dynamic load distribution.


Level 2 vs. Level 3: Strategic Deployment

Choosing the right charging technology dictates your entire electrical engineering roadmap.

High-Density Level 2 Charging (208V/240V AC)

  • Deployment Strategy: Office parks, multi-family condos, hotels, and employee parking where dwell times exceed 3-4 hours.
  • Power Requirements: Each commercial unit typically requires a dedicated 40A to 80A circuit.
  • The Challenge: While an individual Level 2 charger has a moderate draw, a network of 20 chargers demands a staggering amount of sustained power, requiring dedicated subpanels and substantial conduit infrastructure.

Level 3 DC Fast Charging (480V DC)

  • Deployment Strategy: Logistics fleets, highway retail centers, and fast-turnaround delivery depots.
  • Power Requirements: These units bypass the vehicle’s onboard inverter, pushing high-voltage DC current directly into the battery. They demand 480V 3-phase power and can pull anywhere from 50kW to 350kW per station.
  • The Challenge: DC Fast Chargers almost universally require coordinated utility upgrades. Solomon Electric facilitates the engineering of new utility switchgear, concrete transformer pads, and step-down transformers to handle these immense loads.

Overcoming Infrastructure Bottle-Necks

The primary hurdle in commercial EV deployment is the building’s existing electrical service capacity. If your facility possesses a 1,200-amp 3-phase service that is already operating at 80% capacity, you physically cannot add ten EV chargers without intervention.

We solve capacity limitations through Active Load Management (ALM).

How Active Load Management Works

Instead of provisioning a dedicated 40-amp circuit for every single charger, ALM software intelligently networks the chargers together on a shared circuit.

  • If one vehicle is charging, it receives maximum power.
  • If four vehicles plug in simultaneously, the software dynamically throttles the current delivered to each vehicle, ensuring the total combined draw never exceeds the breaker’s safe limit.
  • As vehicles finish charging, power is automatically re-routed to those still charging.

This allows property owners to double or triple the number of installed charging ports without triggering a half-million-dollar utility service upgrade.

The Installation Process

A successful commercial rollout follows a strict engineering protocol:

  1. Feasibility & Load Study: We deploy telemetry to record your building’s peak demand, identifying exactly how much surplus capacity exists.
  2. Civil & Trenching Logistics: Commercial charging requires extensive underground conduit. We map out the most cost-effective trenching routes to minimize asphalt disruption and parking lot downtime.
  3. Utility Coordination: If a new dedicated meter and transformer are required, we manage the permitting and engineering submissions with FPL or your local utility provider.
  4. Network Commissioning: We integrate OCPP-compliant chargers onto a commercial software network, allowing you to track energy usage, set billing rates for the public, or provision RFID access for a private fleet.

Preparing a facility for the electrified future is a complex capital endeavor. Partner with Solomon Electric’s commercial division to ensure your infrastructure scales flawlessly and safely.

Frequently Asked Electrical Questions

Level 2 charging uses 208V/240V AC power and adds roughly 20-30 miles of range per hour, ideal for employees or hotel guests parking for long durations. Level 3 (DC Fast Charging) uses 480V DC power, charging vehicles in 20-40 minutes, ideal for fleets and highway retail corridors.

Likely not without an electrical upgrade. Ten Level 2 chargers operating simultaneously can draw an additional 400 to 800 amps. A comprehensive load analysis and potential utility transformer upgrade are often required.

Active Load Management is smart-grid software that distributes available electrical capacity across multiple charging stations dynamically. It prevents the building's main breaker from tripping and allows you to install more chargers than your fixed electrical panel would traditionally allow.
