Battery Energy Storage System (BESS) Solution
Transformer solutions for grid-scale and C&I battery storage — PCS-adapted, bi-directional, harmonic-tolerant. From PCS step-up to grid connection, with containerized options.
PCS Adaptation & Bi-directional Operation
Engineered around the inverter — every unit is matched to the PCS it serves, not the other way round.
PCS-to-Transformer Interface
Transformers matched to PCS output characteristics: voltage, current, harmonic spectrum, and switching frequency.
Charge & Discharge
Bi-directional power flow design — transformer handles both charging and discharging cycles without derating.
Cyclic Loading Design
Thermal design optimized for cyclic loading patterns typical of BESS operation, ensuring insulation longevity.
Key Technical Parameters
Standard design envelope — every project is then tuned to site and PCS data.
