Behind-the-Meter Energy Storage

Stalwart Power selected Nuvation BMS to manage their 50 V battery energy storage system for grid-attached, behind-the-meter energy storage. The Stalwart system was a 17.5 kWh lithium-ion phosphate energy storage system that utilized a Schneider PCS.

Stalwart selected batteries for the system, but needed to replace the manufacturer’s bundled battery management system because it was not designed to support deployment at the utility.

Stalwart chose to replace the BMS with Nuvation BMS due to its remote monitoring capabilities. Nuvation BMS has the ability to remotely monitor an energy storage system and flag potential issues that would merit a service call, before it impacts system safety or performance.

Nuvation Energy performed all aspects of system integration for this project. Our software team also developed a custom site controller that performed PV smoothing and load balancing functions.
