The INPPCS-450 module is a modular energy storage inverter designed for 1500Vdc battery systems. The module DC side supports up to two branches of access and string management separately. With a rated power of 450kW and three-level topology, it supports multiple functionalities and delivers exceptional performance in large-scale commercial/industrial applications and medium-voltage (MV)/High-voltage (HV) step-up scenarios. Featuring a wide DC voltage range and IP66 protection rating, this product ensures enhanced flexibility and reliability in diverse operational environments. Based on liquid cooling design and integrated with HV box, the overall energy density is higher and the application adaptability is stronger.
