Description

The cabinets sit on a Flex Mount Skid mounting frame and ship one by one, with no oversized container to move. The operating mode sets power, 4180 kW over a two-hour cycle or 2090 kW over four hours, with DC round-trip efficiency of 93 % and 94 %. Inside are 314 Ah LFP cells, the enclosure is IP55 / NEMA 3R, and the operating range is −30…+55 °C. Service life is up to 20 years. The PCS is chosen separately, as the system works with the main inverter types. Its certificate set, IEC 62619, IEC 63056, IEC 62477-1, IEC 62933-5-2, UL 9540A, NFPA 855 and UN38.3, matches the SolBank 3.0 Plus container, which simplifies review of mixed projects.

How to choose

FlexBank suits projects where logistics and a capacity step of 1,672 kWh matter more than a whole container. If the site has room for a crane and heavy equipment, a SolBank 3.0 Plus container at 5,016 kWh goes up faster. Where space is short, the SolBank 4.0 holds 6.25 MWh per container.
