Tritium, a US-based manufacturer of EV fast chargers, has introduced GRID-FLEX, an 800 VDC bidirectional inverter platform targeting data centers, utility-scale renewable energy sites and battery energy storage systems. The company describes GRID-FLEX as addressing challenges in power efficiency and grid integration, particularly as data centers handle increasing AI workloads and as renewable energy projects scale up connection requirements.
Tritium says that GRID-FLEX’s bidirectional architecture not only increases electrical efficiency but also enables facilities to generate revenue through grid services and demand response. For data centers, the system is designed to deliver higher computing capacity within existing power constraints by reducing conversion losses through its native 800 VDC topology.
It’s designed to be deployed in 3.2 MW blocks, which can then be paralleled in groups of three via a Bus Combiner for 9.6 MW distribution to 800 VDC-powered servers.
“Data center operators are hitting power walls—they need more computing capacity but can’t get large utility connections in time. Likewise, solar and battery energy storage developers are facing increasingly complex grid interconnection requirements,” said Arcady Sosinov, Tritium’s CEO. “GRID-FLEX solves both problems with the same core technology: our liquid-cooled power modules that we’ve refined over two decades in demanding use cases including ultrafast EV charging. Native 800VDC eliminates conversion losses for data centers, while our bidirectional capability turns renewable assets into grid resources that utilities actually want to connect.”
For renewable energy and battery installations, GRID-FLEX features dynamic reactive power compensation (±0.9 power factor), fault ride-through, and direct integration with solar arrays and battery storage, meeting various global utility interconnection standards. The modular platform scales from 400 kW to 3.2 MW using proprietary 50 kW liquid-cooled modules and achieves 98.5 percent peak efficiency. The platform also delivers two to three times the power density of leading utility-scale inverters, is housed in IP65-rated enclosures suitable for environments from -35°C to +55°C, and offers a 10-year power module warranty.
GRID-FLEX is manufactured in the US and continues Tritium’s transition into broader infrastructure markets following its acquisition by Exicom in 2024.
