The INPPDTMZ-250 is a MPPT integrated microgrid energy storage inverter cabinet. It can integrate 1 to 2 high-performance SiC-based PCS modules (model: INPPCS-125) with three-phase four-leg topology, supporting flexible design configurations such as AC/DC parallel connection or string-specific management to optimize power adaptability and system integration flexibility. The PV side can integrate up to 6 MPPT modules, with a total rated power of 375 kW. This solution enables versatile deployment across diverse scenarios including C&I energy storage, distribution energy storage, solar-storage-charging integration, mining drilling, and construction sites. It provides robust support for critical energy management requirements such as peak shaving, power factor correction, harmonic mitigation, and power quality enhancement.
