The Huawei 4.6K-LB01 is a single-phase hybrid inverter designed to maximize self-consumption and make your PV system battery-ready with plug & play integration for Huawei LUNA2000 storage. It combines advanced active safety, smart monitoring via FusionSolar, and compatibility with Huawei optimizers to help improve energy yield—especially on complex roofs.
Battery-ready (HV) with simple integration: dedicated interface for Huawei LUNA2000 batteries (S0 and S1 series).
2 independent MPPTs: efficient management of two PV strings with different orientations or partial shading.
High efficiency: up to 97.8% (European efficiency 97.0% on the 4.6K model).
Advanced safety: includes arc-fault protection (AFCI) plus comprehensive AC/DC protections.
Outdoor-ready & silent: IP66 enclosure, natural convection cooling (no fan noise), and night consumption < 3 W.
Optimizer compatible: supports Huawei optimizers (DC MBUS) to increase yield at module level (actual gain depends on roof/layout).
Compatible with:
LUNA2000-5/10/15-S0
