Next week we're in Las Vegas for RE+ 2026, November 17 to 19. You'll find us at booth C7082 in the Central Hall, which we're sharing with Swap Robotics.
This year, we wanted to build the booth out of real hardware highlighting two important microgrids: an EV fleet depot and an 800 V DC data center. The devices come from more than a dozen vendors, and every one of them is fully simulated in software directly inside the Voltra platform, keeping the site inside the limit the utility sets.
Why build it? More sites are making their own power instead of waiting years for new grid capacity, fleet depots and data centers first. That only works when software can see and control everything on site, from the utility connection down to each rack, charger, and device. It is critical to understand the status and harmony of a site end-to-end, and a booth with real hardware you can walk through is the clearest way we've found to show it.
The fleet depot
The fleet depot starts at the utility connection, where an SEL-751 relay protects the main and Accuenergy meters measure both the main and every individual charger circuit, with a PSP Products disconnect providing physical protection on the charger feed.
From there, the depot brings together chargers from several different vendors. A Fractal EV charger and a Wallbox charger take their power limits from Voltra over OCPP, a Heliox bidirectional charger demonstrates vehicle-to-grid, and an XCharge GridLink adds a charger with its own built-in battery. A Digi cellular router keeps the whole depot connected, while Voltra Edge coordinates every device to hold the site under its limit.
On the other side of the same feeder, Elastic Energy is showing its Energy Router, which brings the solar, batteries, and other equipment in nearby homes and businesses under one control, making them flexible for the grid.
The 800 V DC data center
The data center is focused on getting power to the racks reliably and quickly. SEL-787 and SEL-751 relays protect the transformer and the feeder, an SEL-735 meter measures the point of connection, and an SEL RTAC reads data from all of them. CE+T Power converters produce 800 V DC and 48 V DC for the racks, a Packet Power gateway monitors every rack circuit, and Moxa industrial switches and edge computers connect the devices and run Voltra's edge software on site.
At the end of the booth, we have a full-scale 800 kW Tritium GRID-FLEX cabinet, which serves as the power layer for the DC site and gives a real sense of the scale of the hardware involved.
The utility wall
The third wall shows how a site works with its utility. The utility sets a limit for the site, and Voltra Edge keeps every charger, battery, and load inside that limit, using flexible resources to add headroom and recording every action along the way.
We have tested our IEEE 2030.5 work against the PNNL reference server, and at the V2G Forum we ran vehicle-to-grid end-to-end, from a utility signal all the way to a school bus sending power back to the grid.
Come say hello
If you're at RE+, come by booth C7082 in the Central Hall. Whether you run a fleet depot, a data center, or a site somewhere in between, we'd love to hear about what you're working on and walk you through the demo. If you'd like to set a time in advance, you can book a meeting here.
