Brand: Prostar
Commodity name: Micro Inverter 1600W-2250W (4 MPPT)

Prostar NBQ Series Micro Inverter delivers enhanced power optimization for residential and small commercial applications through a dual-module architecture (1600W-2250W, 4 MPPT). By independently managing two PV panels with dedicated MPPT channels, it extends the advantages of module-level power electronics—notably mitigating shading and mismatch losses—to installations where partial roof orientations or intermittent obstructions challenge traditional string inverter performance. Engineered with IP67 ruggedness and integrated anti-islanding protection, the series ensures reliable grid interaction while enabling granular, per-panel monitoring for precise system oversight. This configuration balances elevated energy harvest with cost-effective deployment, offering a scalable and resilient solution for projects requiring higher power density without compromising the reliability and diagnostic clarity inherent in distributed inverter topologies.
