What is a Bess battery?

The small BESS series is a fully integrated battery energy storage system that's built to last. The Series is both scalable and engineered for modularity with a low MTTR, making it ideal for medium renewable energy projects. It offers flexible and scalable designs for various applications, whether you need a small or medium energy storage solution.

How efficient is a Bess battery system?

The BESS shall have a DC round-trip efficiency of > 90% when charged and discharged at 2 C (7.5 MW). The Contractor to indicate the efficiency of the system at the rated discharge and charge power levels and any degradation thereof as battery system ages.

What are the different types of Bess cabinets?

Our BESS is modular, which means you can mix and match cabinets to suit your system requirements. Plus, it comes in two variants, AC Single Bay and AC Dual Bay. Medium BESS Cabinets The medium series battery energy storage system is designed with versatility and scalability in mind.
