For 600 VAC-class, grid-connected battery energy storage applications utilizing solar, Dynapower offers its Solar Power Systems™ (CPS) family of utility grade, bi-directional, true four-quadrant, Digital Signal Processor (DSP) controlled inverter/converters. Dynapower’s flexible and highly modular SPS optimizes the transfer of energy between a DC energy storage system and a three-phase grid. The SPS provides power conditioning (voltage and frequency support) for intermittent loads and renewable generation. Systems are available in indoor and outdoor configurations.

The SPS integrates system cooling, controls and a full complement of switchgear and protection including an AC circuit breaker, AC contractors, AC & DC Fusing, DC load break contractors, a DC manual isolation switch into a single, heavy duty industrial enclosure. This offers end users and energy storage integrators a cost advantage when compared to non-integrated systems that require additional add-on items.

Dynamic Transfer™ — Dynapower’s proprietary patent pending Dynamic Transfer algorithm monitors the grid stability and upon detecting a grid disturbance will disconnect from the grid connection and transition to stand-alone mode on the load connection. The transition is seamless to the critical loads and supports 100% phase imbalance in UF mode.

The CPS provides two modes of operation — Grid-Tied (PQ-mode) and Stand-Alone (UF mode). In the Grid-Tied mode, the CPS controls the AC output real power (P) and reactive power (Q). In Stand-Alone mode, the CPS controls the AC output voltage (U) and frequency (F). The system can be started in either mode and the transfer between modes is done dynamically. Advanced controls schemes for multi-unit and microgrid applications are available.

Dynapower’s state of the art control and monitoring platform provides operators with both local and remote operation of the system. In the remote operating mode, a communication link provides autonomous operator control via Ethernet, RS232, or RS485. For local control, Dynapower provides an Operator Interface Terminal (OIT) for error set commands and full system display status.

The CPS provides full system status information including AC output real & reactive power, AC output voltage & frequency and DC battery voltage and DC current readings to the remote operator through feedback signals or through the communication link (via an RTU or PLC). The CPS has an on-board monitoring system with error history and grid fault data capture. System operating information is displayed on the OIT in both local and remote modes of operation.
