This fully integrated storage system combines our UL-1741 SA certified CPS energy storage inverters with Li-Ion batteries in an outdoor-rated battery enclosure with all associated controls and protection features.
The CPS-i is a high-performance system designed to provide consistent, reliable power. It is easily deployed on a concrete pad, crushed stone or on the ground with a forklift and minimal labor, reducing system installation costs. Multiple CPS-i systems can be paralleled together to meet the sizing needs of any front-of-the-meter or large behind-the-meter installation.
When needed for resiliency applications, the CPS-i utilizes our proprietary Dynamic Transfer™ technology to monitor grid stability and, in the event of disturbance, autonomously and immediately shift a microgrid from grid-tied to battery backup power, ensuring a steady flow of electricity for critical applications. In a complete system power outage, our black start capability restores power without the need for external power.

Islanded Operation (UF Mode)
The CPS-i includes the ability to run islanded mode (voltage source) operation, also called UF mode. In islanded mode, the CPS accepts Voltage (U) and Frequency (F) setpoints. The CPS can handle full real power transitions with extremely tight voltage and frequency regulation forming a ‘stiff backbone’ to the microgrid.
Dynapower’s patented Dynamic Transfer™ algorithm monitors grid stability and, upon detecting a grid disturbance, disconnects from the grid and transitions to stand-alone battery backup power mode on the load connection. The transition is seamless to the critical loads and supports 100% phase imbalance in UF mode.
In the event of a complete system power outage, our patented black start restores power to the facility without the need for external power. Dynapower’s black start technology can start distribution networks even with transformer magnetizing currents that exceed the power rating of the inverters. Multiple CPS® units can be restarted at once.
Frequency Compensation Mode (F- Comp)
F-Comp monitors the grid frequency for deviations from nominal, and if a deviation exceeds a max allowed, the CPS will automatically follow a user-defined frequency correction curve. F-Comp is ideally suited to very rapid Fast Frequency Regulation applications as well as power quality correction of critical facility loads.
Volt-VAR Compensation Mode (E-Comp)
E-Comp monitors the grid voltage for deviations from nominal and automatically attempts to correct three-phase voltage magnitude deviations (usually voltage sags) experienced by a critical load in an effort to avoid the need to transfer to backup power mode.
AC Current Limiting (In-Rush Current Handling in UF Mode)
The CPS-i has AC current limiting, so that the system will deliver up to (but not exceed) full rated AC current to avoid nuisance AC overcurrent faults due to excessive load inrush current demand. When current limiting in UF, the AC voltage and frequency may deviate from nominal and this is permissible within the CPS abnormal voltage frequency limits and timers. It is expected that, if the system is properly sized to the microgrid, any voltage or frequency deviations due to large inrush loads will be very minor and short duration, and not affect the load.
