The standard configuration includes all core functionality necessary for common BESS applications and is ready to deploy with minimal setup ... For projects requiring additional features, custom logic, or integration with other distributed energy resources, Nuvation Energy also offers the nController Extension Program. ... Provides unified control for one PCS per system, selectable from multiple supported models.Provides dispatch interface for higher-level controls.Provides monitoring and control of BESS auxiliary systems via networked digital IO module (purchased separately from supported suppliers). ... Network SecurityUser authenticationEncrypted communicationsProduct authentication checks Built-in firewallSupply Chain SecurityDesigned and manufactured in the U.S ... and CanadaStrict procurement practicesIntensive quality controls ... Enables battery maintenance execution.Provides parallel battery stack management. Provides parallel stack aggregation and intelligent control.Manages 1-16 parallel battery stacks on a shared DC-bus.Calculates State of Charge and Depth of Discharge of the unified energy storage system.Aggregates system-wide faults and warnings and provides battery pack diagnostics.Functions as a data analytics gateway by providing access to battery measurements for data capture. ... Local data logging.Remote Support Monitoring to facilitate pilot system integration support. Optional Touch Screen HMI (Hardware not included).Optional fiber optic networking supported through 10G SFP+ ports.Two form factor options: 1U rack mountCompact form factor, ruggedized (SAE J2464, SAE J2380), suitable for use in mobile applications ... Benefits: clients can manage the BESS applications from their own controller or from one provided by a third party, including Nuvation Energy. This enables endless possibilities for managing a BESS without having to deal with the intricacies of the BESS and PCS integration. How: The nController provides SunSpec Information models over Modbus TCP to enable monitoring and control of the BESS. The nController deals with the details for integration between the BESS and the PCS, allowing the higher-level controller to focus on applications at the power and energy interface level. Architecture: Install an AC-BESS block, configure the nController for the BESS limits, configure the higher-level controller for the application. ... Benefits: cost savings through energy cost arbitration and peak energy demand charge reduction. How: Use a schedule to charge during periods of low energy cost or low energy usage and to discharge during periods of higher energy costs or high energy usage. This works best with predictable loads and pricing schedules. Architecture: Install an AC-BESS block and configure the nController schedule for charging and discharging. ... Benefits: protect your load from power outages by using a BESS to provide backup power for a site. How: keep a reserve of energy in the battery for use when the utility grid is not available. The BESS is configured to form a local microgrid to provide power to the local loads when the site is disconnected from the utility grid. When the utility grid comes back, the BESS coordinates reconnection to the utility grid to provide power to the local loads as well as to recharge the BESS. Architecture: Install an AC-BESS block and an automatic transfer switch or grid protection relay. Configure the nController policies to maintain reserve energy, configure the equipment to coordinate transfer between utility connected operation and microgrid operation. ... Ready to Deploy Management for AC-Coupled BESS.

... The Multi-Stack Controller (MSC) is a parallel stack management solution for Nuvation Energy Battery Management Systems ... It aggregates control of all the battery stacks in your energy storage system, enabling you to operate the ESS as a single unified battery ... It also provides individual stack-level control ... The MSC functions as a central battery control hub from which all other ESS control systems (energy controllers, PCS, external communications) can obtain battery data and send control commands to the battery system ... It can be used to manage up to 16 battery stacks in parallel and will bring up stacks in the sequence best suited to the immediate use-case requirement, i.e:, power, energy, or capacity ... Battery system performance data and user controls can be accessed from a locally connected PC or remotely over Ethernet. ...

... An nController Extension Program enables advanced features to be equipped to the nController in addition to the standard product capabilities ... These extensions can enable further opportunity to generate value from your energy storage and other distributed energy resources (DERs) ... For these programs Nuvation Energy works directly with clients to create extensions based on customer-specific application requirements. ... Benefits: Load Following algorithms can be configured to dynamically respond to real-time load changes enabling a more optimized response to peak loads as measured by a power meter. How: Load following algorithm monitors power measurements at the site to determine when to charge and discharge the BESS. Architecture: Install an AC-BESS block and a power metering device at the point of interest ... Configure the nController load following policies with scheduled power and energy set points. ... Benefits: Some jurisdictions require green energy projects to be designed to ensure that energy is not exported from the local site to the utility grid, or if they do allow export sometimes, they do not pay for exported energy. Solar Self Consumption feature manages the assets to store energy locally so that it can be used later when the loads exceed generation. How: The nController monitors site loads, generation, and manages BESS charge and discharge to optimize usage locally of locally generated energy. Architecture: Install an AC-BESS block and a power metering device at the point of interest ... Configure the nController policies with scheduled power and energy set points. Some sites may also require curtailment of generation under certain edge conditions. ... Benefits: Enable control of two or more BESS AC-blocks as if they were one. How: The nController Plant Controller is configured to manage two or more AC-coupled BESS units through their associated nController. The plant controller aggregates the BESS information to allow higher-level controllers to control the set of batteries as if they were one unit.Architecture: Install two or more AC-BESS blocks and an nController plant controller ... Configure the plant controller to connect to the nController for each AC-BESS block. ... Benefits: Coupling generation and loads to the battery DC bus can provide advantages for efficiency and sometimes for control reasons too. It is an architectural decision that impacts the controls design. How: Architectural design, selection of compatible components, and selection of the appropriate algorithms. Architecture: BESS design must support integration of compatible components at the DC-bus. The components must support curtailment. ...
