Description
A cluster takes 5–16 modules of 16 kWh, so capacity is matched to the specific PCS and the discharge duration required. Cluster current is 168–180 A, and the DC cable cross-section and protection rating between rack and PCS follow from it. Cycle life is at least 6,000 charge and discharge cycles, enough for daily arbitrage or peak shaving year after year. The enclosure is IP20, so the racks go indoors or into a climate-controlled container. CE, IEC 62619, IEC 62040 and UN 38.3 certificates are requested during project approval and for transport. The Pro-A3 version runs in the same pairing with a 100–125 kW PCS.
How to choose
The module count follows from PCS power and the hours of discharge needed, and a 215 kWh cluster on a 100 kW PCS runs at full power for about two hours. Sites of several hundred kilowatts use several clusters, each with its own PCS, up to the 2.5 MW system limit. With no indoor room and a need for an outdoor cabinet with the PCS inside, take the MS-G215 at 100 kW and 215 kWh rated IP54. At 250 kW the liquid-cooled MC-L522 with 522.5 kWh is the closer match.
