Key Benefits
2ms output
Microgrid Capable


BESS is "always on". The Vertiv Dynaflex leverages best in class energy output for seamless operations.
Vertiv Dynaflex can be grid forming, regulating voltage and frequency for distributed energy sources within a microgrid, or grid following, maitaining constant output power during load disturbances.
Microgrid islanding capability allows for power generation and ensures reliability during grid outages or when disconnected from the grid.
Utility demand management capability allows BESS controls to monitor and predict the load and respond to daytime power consumption peaks by activating the battery's output to avoid setting a high demand charge. This results in reduced utility costs.
Assists the utility in maintaining localized power grid quality via a direct command control sequence that the controller will receive from the utility grid operators. BESS issues commands to one or all the distributed energy resources (DERs) to respond to the requirement.
Vertiv Dynaflex BESS is always-on for increased reliability and efficiency allowing for higher uptime.
While connected to the grid, the Vertiv Dynaflex BESS controller can be configured to recommend and activate loads at various times of day when utility rates are favorable yet not overly impacting client operations. The BESS can command the system to assist the utility in maintaining localized grid power quality via a direct command control sequence that the controller will receive from the utility grid operator and issue commands to one or all of the DERs to respond to the requirement.
Allows for utilization of renewable energy as a distributed energy resource by providing energy storage, regulating voltage and frequency, and controlling dispatch of available resources.
