Product Overview

Expand EV Charging Without Installing Five Separate Circuits

Installing multiple EV chargers can place significant demand on a building’s electrical infrastructure. In many existing condominiums, multi-unit residential buildings, workplaces, and fleet facilities, sufficient capacity may not be available to operate several chargers simultaneously.

The NEX-1/5-50A provides a practical alternative. One 50 A input circuit supplies an intelligent five-channel EVEMS panel, which then manages five dedicated EV charger outputs.

Instead of requiring a separate feeder circuit for every charger, the available capacity is automatically shared among the connected charging stations. This approach can reduce the amount of electrical distribution equipment, feeder cabling, conduit, and installation work required for an EV charging project.

How the NEX-1/5-50A Works

Intelligent 1-to-5 EV Charging Management

Step 1: One Electrical Input

A dedicated 50 A, 208/240 VAC circuit supplies power to the NEX-1/5-50A EVEMS panel.

Step 2: FiveDedicated Outputs

The panel provides Five separate 50 A output channels. Each channel can be connected to an individual Level 2 EV charger configured for a maximum charging current of 40 A.

Step 3: Automatic Power Allocation

The integrated control system manages the charging outputs so that the total demand remains within the available capacity of the shared input circuit.

Step 4: Fair Charging Access

When multiple vehicles are connected, the system automatically coordinates charging access among the active outputs. This allows multiple residents, employees, or fleet vehicles to share the available electrical infrastructure without manual intervention.

Step 5: Continuous Operation

The charging sequence continues automatically as long as vehicles remain connected and require charging.

Standalone Mode

In standalone configuration, one NEX-1/5-50A panel independently manages up to five connected EV chargers.

This configuration is suitable for:

  • Small condominium installations
  • Five parking stalls
  • Small commercial properties
  • Employee charging areas
  • Residential developments
  • Small fleet applications

Network-Enabled Mode

For larger projects, multiple NEX panels can be incorporated into a coordinated EV charging network.

This configuration is suitable for:

  • Small condominium installations
  • Five parking stalls
  • Small commercial properties
  • Employee charging areas
  • Residential developments
  • Small fleet applications

Ideal Applications

A Practical Solution for Shared Parking Facilities

The NEX-1/5-50A is designed for projects where several vehicles require access to Level 2 charging but the available electrical capacity is limited.

Condominiums and MURBs

Provide EV charging access to multiple residents without assigning a completely separate feeder circuit to every parking stall.

Townhouse Developments

Create shared or grouped EV charging infrastructure for resident parking areas.

Workplace Charging

Allow several employees to connect their vehicles throughout the workday using a managed electrical supply.

Fleet Parking

Coordinate charging across a small group of fleet vehicles that remain parked for extended periods.

Commercial Properties

Add EV charging amenities for tenants, employees, or visitors while managing available electrical capacity.

Existing Buildings

Introduce EV charging infrastructure in properties where electrical service upgrades may be difficult, disruptive, or expensive.

Project Savings

Reduce the Infrastructure Behind the Chargers

The cost of EV charging infrastructure extends beyond the charging stations themselves. Breakers, feeders, conduit, distribution panels, installation labour, and electrical service capacity can represent a significant portion of the total project cost.By allowing five EV chargers to share one managed 50 A circuit, the NEX-1/5-50A can simplify the electrical design and reduce the amount of upstream infrastructure required.Actual savings depend on the building, installation distance, electrical capacity, charger selection, local requirements, and project design.

  • Fewer upstream
  • circuits
  • Reduced feeder cabling
  • Less conduit
  • Fewer breaker positions
  • Simplified distribution
  • Reduced need for electrical upgrades

No. The system has one 50 A electrical input and five managed output channels.


No. The panel’s total available power is limited by its single 50 A input. The EVEMS coordinates charging among the connected outputs so the available input capacity is not exceeded.


Each connected EV charger can be configured for a maximum charging current of 40 A when supplied by its 50 A output channel, subject to the approved project design and applicable electrical requirements.


The system manages power on the supply side of the charging stations and is intended to support compatible Level 2 EV chargers. Charger compatibility and control requirements should be confirmed during project design.


Yes. The NEX-1/4-50A can operate as a standalone four-channel EVEMS.
