Description
The system is built as an integrated AC-DC unit, meaning the PCS converter sits in the same block as the batteries. This reduces the number of separate cabinets and cable runs between the batteries and the converter. The liquid loop keeps the temperature spread in the system below 2.5 °C, and an even cell temperature means more uniform ageing of the whole string. Active balancing works across the entire battery string, not separately in each module. The declared cycle life is 15 000 cycles, which matters for daily cycling in grid projects. Fire protection has four levels.
How to choose
Choose this model when you need a 6.25 MWh unit with the converter included. For smaller projects, Center L comes in a 20-foot container with liquid cooling and a cycle life of over 10 000 cycles. Center F containers come in 20 and 40 ft formats with a DC voltage of 1500 V or 1000 V, and the 372.7 kWh Edge FL cabinet suits commercial and industrial sites.
