NEXPHASE™ Smart EV Switchgear

The NexPhase™ Smart EV Switchgear is an all-in-one switchgear enclosure containing the entire infrastructure required between the utility service and up to four Level 3 DC fast chargers. Unlike any switchgear of its kind, the NexPhase™ Smart EV Switchgear features cutting-edge grid intelligence and EV charger remote monitoring and control.


As a result of the National Electric Vehicle Infrastructure (NEVI) Formula Program that provides funding for strategically deploying electric vehicle charging infrastructure along major US highways, many utilities are looking to incorporate EV chargers into their existing sites. NexPhase™ is an all-in-one, NEVI-focused intelligent switchgear solution that enables site owners to maintain higher charger uptimes while minimizing installation, maintenance, and operating costs.

By combining all switchgear equipment into one enclosure, NexPhase™ eliminates the lengthy design process of traditional post-and-frame systems, which require additional costs to design and source a mixed-manufacturer panel system.

Remote Monitoring & Control

An embedded monitoring system provides remote access to real-time health data with remote power cycling capabilities and automated alarms to facilitate condition-based maintenance planning.

Pinpoint Off-Line EV Chargers

It’s approximated that up to 25% of public U.S. EV chargers are out of operation at any given time, with these outages going undetected until a technician is physically present. NexPhase™ provides ongoing state-of-charge data so operators can identify outages and remotely cycle power to maintain the 97% uptime requirement set by the NEVI guidelines.

Mitigate Up-Front Costs

NexPhase™ only requires the on-site connections for the incoming power and outgoing charger connections, drastically reducing on-site installation time and costs.

Protect Your Site

NexPhase™ includes integrated emergency-stop capabilities for NFPA compliance and added safety features including EV charger crash detection and flammable gas monitoring with automatic shutdown and remote alerts.

A switchgear is a critical component of a DC fast charger station's infrastructure. Tasked with receiving, distributing, and protecting the site’s power, switchgear is typically composed of a series of electrical panels. Traditionally, these post-and-frame switchgear systems have been comprised of multiple mixed-manufacturer electrical panels that are wired together on-site during installation. NexPhase™ is a Buy America Compliant Component that provides an integrated, single cabinet, ready-to-install solution to minimize the complexity and effort required to install a switchgear that fulfills NEVI requirements.


NexPhase™ combines a Current Transformer (CT) cabinet, 480 VAC 3-Phase breaker panel, 240/120 VAC single phase breaker panel, and transformer into a single enclosure.


Eliminate the additional resources, time, and supply chain difficulties often associated with designing and sourcing a mixed-manufacturer post-and-frame switchgear systems.


All internal components come pre-installed and pre-wired. With a shortage of qualified, veteran electricians available, NexPhase™ makes it easy to execute more EV charger projects with existing workforces.

NexPhase™ securely communicates with the UNITE™ user interface, providing user-friendly access to monitoring information including transaction analysis, energy consumption, charge duration, EV charger state, utility power monitoring, and remote control capabilities. Combined, the monitoring information can help operators reach the 97% uptime requirement set by NEVI. These data gathering and control capabilities may also be integrated into existing software platforms.
