The INPBESS-1500 is a high-energy-density solution integrated with a string inverter architecture. By connecting 12×125kW modules in parallel, a system power of 1.5MW was achieved. Supporting multi-branch DC side design, providing more options for battery management. Its DC side employs liquid-cooled 628Ah battery cells to minimize system losses while ensuring precise temperature control, significantly enhancing system reliability and stability. The AC side delivers 400Vac output, the design of 3-phase and 4-wire can better connect to the power grid or support loads without connecting transformers. Designed for seamless compatibility with multiple scenarios — including peak shaving, load shifting and frequency regulation, and large-scale microgrids — this solution stands out for its flexibility, stability, and adaptability.
