Specifications
Product Description
The Huawei SUN2000-4K-LB0 4kW Single-Phase Hybrid Inverter belongs to Huawei's Smart Energy Controller series, designed to deliver maximum output in residential installations and prepare your system for high-voltage battery storage. It integrates a grid inverter, battery charger, and communications in a single compact IP66 chassis. Its two wide-range MPPT trackers allow you to maximize energy on roofs with multiple orientations, while its active protections (AFCI, type II SPD on DC/AC) and monitoring via the FusionSolar app provide professional safety and control.
Main Features
- 4 kW nominal power for single-phase homes with medium consumption.
- 2 independent MPPTs with a range of 40–560 V, max. PV voltage 600 V, and start-up voltage 50 V.
- 16 A current per MPPT and Isc 20 A: suitable for high-current modules.
- Max. efficiency 97.8% (EU ~96.8%), resulting in more kWh utilized per year.
- Ready for HV battery Huawei LUNA2000 (350–580 V, 20 A) with charge/discharge managed directly from the inverter.
- Backup for essential loads via SmartGuard 63A-S0 or Backup Box-B0.
Advantages or Benefits
- Immediate savings: higher output and the possibility to shift night-time consumption with a battery.
- Service continuity during grid outages thanks to backup mode for critical circuits.
- Quick and clean installation: integrated WLAN, guided commissioning, and lightweight design.
- Enhanced safety with AFCI, SPD II on DC/AC, anti-islanding, and insulation monitoring.
- True scalability: start without a battery and expand when needed without changing the inverter.
Purpose or Applications
Ideal for single-phase homes with medium consumption, gable roofs or pergolas with different orientations, small businesses at 230 V, and projects looking to add storage now or in the future. Also recommended for second homes requiring backup for essential loads.
