Huawei 4.6K-LB01 Hybrid single-phase inverter

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. Why choose it 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). Battery compatibility (Huawei storage) Compatible with: LUNA2000-5/10/15-S0 LUNA2000-7/14/21-S1 Battery (DC) specs: Voltage range: 350–560 Vdc Max current: 16.5 A Max charge power: 6,000 W Backup / EPS (optional) The inverter supports backup output, available via SmartGuard-63A-S0 (dedicated accessory/solution). Key technical highlights (4.6K model) PV input Recommended PV power: up to 6,900 Wp Max PV voltage: 600 V Start voltage: 50 V MPPT voltage range: 40–560 V 2 MPPT / 1 input per MPPT Max current per MPPT: 16 A (Max Isc 20 A) Grid (AC) output Rated power: 4,600 W Max apparent power: 5,000 VA Max current: 23 A THD: ≤ 3% Power factor adjustable: 0.8 leading … 0.8 lagging Installation & connectivity Dimensions: 425 × 376.5 × 150 mm | Weight: < 15 kg Operating temperature: –25 °C … +60 °C Communications: RS485 + built-in WLAN (FusionSolar App); Ethernet/4G via optional dongles Ideal for Residential single-phase systems that want to reduce grid import and increase self-consumption. New installs or retrofits that need a battery-ready inverter with future upgrade to Huawei LUNA2000. Roofs with multiple orientations thanks to 2 MPPTs.
