CPS-1250 / CPS-2500 Energy Storage Inverters

Industry-Leading Power Density and Configuration Flexibility

Find out more.

Featuring a highly efficient three level topology, the CPS-1250 and CPS-2500 inverters are purpose-built for energy storage applications, providing the perfect balance of performance, reliability, and cost-effectiveness.

The CPS-1250 and CPS-2500 are 1336 kVA (CPS-1250) and 2672 kVA (CPS-2500) bidirectional four quadrant capable converters. Both the CPS-1250 and CPS-2500 offer AC input voltage from 350V_AC to 800V_AC and DC voltage range from 511V_DC to 1500V_DC. Available in indoor and outdoor-rated configurations, units can be paralleled for project size scaling to meet the needs of any grid-tied or microgrid application.

Capable of connecting to an 800VAC 3 phase grid connection, the CPS-1250 and CPS-2500 offer industry-leading power density and efficiency. The CPS-2500 allows DC input configuration flexibility to enable large duration battery connections or reduce balance of system costs through input consolidation.

CPS inverters contain all required protective features, including an AC output breaker and DC pre-charge. This creates a cost savings compared to other inverters that require additional items for battery integration.

AC Current Limiting

The CPS 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.

Low Voltage Ride Through (LVRT) with Active Current Injection

In the event the grid experiences a voltage sag, the CPS will enter into low voltage ride-through operations to maintain proper AC voltage connection. The CPS inverter will enter either Momentary Operation, where the converter supplies at least 80% active current command, or Momentary Cessation, where the converter ceases to export active current but does not fault. The trip levels and trip times for the LVRT settings are configurable by the end user and meet the requirements for IEEE 1547.
