## Huawei SUN2000-4K-LB0 - 4 kW 1-phase hybrid inverter


The Huawei SUN2000-4K-LB0 is an advanced 1-phase hybrid inverter that maximises solar energy yield while offering flexibility through battery integration. This inverter is an essential component for modern, residential solar energy systems.


### Key Features


- **Power and Efficiency:** The inverter has a nominal AC power output of **4000 W** and a maximum apparent power of **4400 VA**. The maximum DC input power is **6000 W**.
- **Hybrid Functionality:** Direct compatibility with Huawei LUNA2000 battery systems, allowing the inverter to not only convert energy from solar panels but also to charge and discharge the battery.
- **Two MPP Trackers:** Ensures optimal yield, even with complex roof configurations with different orientations or shading.
- **Integrated Communication:** Equipped with standard WLAN for easy monitoring and configuration via the FusionSolar app. RS485 and optional dongles offer further communication possibilities.
- **Arc-Fault Circuit Interrupter (AFCI):** An active safety feature that automatically shuts down upon detection of an electrical arc, which minimises the risk of fire.


### Main Benefits


- **Maximum Energy Efficiency:** With a Euro-efficiency of **96.8%** and the possibility of optimizer integration, this inverter achieves a high energy yield from your PV installation.
- **Future-proof and Scalable:** The plug-and-play design enables seamless integration of the** [LUNA2000 battery systems](https://www.estg.eu/en-gb/assortment/energy-storage/home-battery?system=Huawei%20LUNA2000)**, making it easy to expand storage capacity later.
- **Intelligent Monitoring:** The FusionSolar app provides real-time insight into energy production, consumption, and battery status, which facilitates efficient energy management.
- **High Safety:** In addition to arc-fault detection, the inverter features Type II surge protection on both the AC and DC sides and has a robust IP66 enclosure.
- **Quiet Operation:** The inverter uses natural cooling, which ensures quiet operation and reduces the risk of mechanical failure.


### Applications


The Huawei SUN2000-4K-LB0 is particularly suitable for residential solar panel installations. Thanks to its compact dimensions and quiet operation, it can be mounted both indoors and outdoors. The hybrid functionality makes the inverter ideal for projects where future or immediate energy storage is desired, for example, to increase self-consumption.


### Warranty and Durability


The inverter has an **IP66** protection rating, which means it is completely dust- and water-resistant. The wide operating temperature range of -25°C to +60°C guarantees reliable performance under various weather conditions. The standard factory warranty is **10 years** from 180 days after shipment.
