The INPMPPTZ-500 is an integrated MPPT cabinet designed for 1000Vdc systems. It can integrate 1 to 8 high-performance silicon carbide (SiC)-based MPPT modules (model: INPMPPT-62.5). Each four-leg module supports up to 4 PV input strings, enabling the entire cabinet to accommodate a maximum of 32 PV strings. Every MPPT string independently performs maximum power point tracking (MPPT), maximizing PV conversion efficiency and enhancing overall project profitability. This product is widely applicable in scenarios such as: C&I self-consumption energy storage projects; Island off-grid power supply systems; Power compensation in industrial facilities; Grid peak-shaving and frequency regulation; PV-integrated charging stations with energy storage, and more. It provides a continuous energy source for battery replenishment. When configured with a PCS (Power Conversion System) in a DC-coupled system, this product can also establish a flexibly interconnected system centered on a DC bus, delivering robust support and protection for the overall power architecture.
