Take Control of Your Energy Storage System

Field-Proven, UL 1973 Recognized

Nuvation Energy’s battery management systems are field deployed in over 130 energy storage systems worldwide. Our highly flexible battery management solutions can be configured for most battery chemistries, modules and stack designs, and used in any storage application. Our high- and low-voltage BMS modules are designed for long-term reliability and are UL 1973 Recognized for functional safety.

Use It Anywhere You Need a BMS

  • Utility grid support
  • Commercial and Industrial (C&I) facilities
  • Residential energy storage
  • Specialty vehicle applications

Configurable for Almost Any Battery Chemistry

  • The user-friendly Operator Interface enables you to configure your BMS for different battery chemistries and customize operational parameters for your target application.

Provides Multiple Safety Layers

  • UL 1973 Recognized functional safety settings are factory-locked to balance flexibility with safety.
  • Includes built-in coil drivers that can energize and de-energize up to four contactors.
  • Provides bi-directional contactor control to reduce the risk of contactors arcing and welding during disconnection under load.
  • Disconnects the batteries from the power path if safety thresholds are exceeded or contactors become damaged.
  • BMS modules include dual independent failsafe processors that monitor each other.
  • Detects faulty voltage and temperature sensor wiring or fused contactors and will not connect the stack if they are present. Service personnel can identify the location of faulty sense wire connectivity issues via the BMS Operator Interface.

Manages Batteries

  • Provides the PCS with access to battery performance thresholds as well as real time voltage, current, temperature, State of Charge (SOC), and Depth of Discharge (DOD) information.
  • Scales back current thresholds as batteries approach maximum SOC and DOD, reducing risk of overcharge and over-discharge by the PCS.
  • Balances lithium-ion and other battery chemistries during the charge cycle.

Integrates Parallel Stacks with ESS Controls

  • The Multi-Stack Controller provides intelligent multi-stack management for up to 36 stacks in parallel, as well as connectivity to local and remote ESS control systems.
  • Provides real-time battery data directly to ESS environmental controls and other safety systems.
  • Receives commands from ESS control systems without the middleware typically required by other battery management systems.

Firmware Update and Feature Additions

  • All our customers are eligible to receive firmware updates and feature additions, ensuring that your BMS software can be upgraded in the future to support new technologies.

“As one of the most reliable and well-designed battery management systems available today for energy storage, e2’s use of Nuvation Energy’s BMS in our energy storage system supports that worry-free promise that our customers depend on.”

James Richmond

President and CEO of e2 Companies

“Nuvation Energy’s battery management system impressed us with how reliably it managed our batteries. It is also easy to integrate with the range of inverters we support, and has a highly intuitive user interface for configuring the system and viewing battery status information.”

Brandon Williams

CEO of Iron Edison

“Between the efforts of POWERSYNC, Nuvation, and Maximo Solar, we developed an energy storage solution capable of providing our clients with a unique and scalable turnkey microgrid for commercial applications.”

Steve May

President of POWERSYNC Energy Solutions

“Nuvation Energy’s battery management systems and energy controller were easy to integrate, and their engineering team provided ESS designs that significantly reduced time to market.”

Trygve Burchardt


“A key requirement was for the BMS to enable remote monitoring of the BESS and to flag any potential issues that would merit a service call, before it impacted system safety or performance. In terms of selecting a replacement BMS, the high configurability of Nuvation BMS made it very easy to integrate into Stalwart’s BESS.”

Woody Gibson

CEO of Stalwart Power
