Huawei SUN2000-4K-LB0 4kW Single-Phase Hybrid Inverter with Integrated AFCI Ready for battery connection mpn: 01077158
The Huawei SUN2000-4K-LB0 represents the new generation of LB0 series single-phase hybrid inverters, designed to deliver maximum flexibility for residential applications, including small-scale photovoltaic systems. Thanks to its high conversion efficiency of up to 97.8%, advanced integrated safety features, and battery-ready design, it provides a complete solution for maximizing self-consumption and increasing household energy independence.
Compatible with Huawei LUNA2000 high-voltage battery storage systems, it allows batteries to be integrated either during the initial installation or at a later stage, ensuring maximum flexibility for both new and existing PV systems. The Battery Ready technology enables energy storage to be added without invasive modifications or additional equipment.
Equipped with two independent MPPTs, AFCI (Arc Fault Circuit Interruption) protection, an IP66 protection rating, and intelligent monitoring through the FusionSolar platform, the SUN2000-4.6K-LB0 delivers outstanding reliability, safety, and performance under all operating conditions.
High Efficiency and Smart Energy Management
Engineered for superior performance, the Huawei SUN2000-4K-LB0 delivers an impressive maximum efficiency of 97.8%, ensuring optimal energy production and minimal losses.
Equipped with a 16A MPPT input current, it is fully compatible with the latest high-power photovoltaic modules, allowing greater design flexibility and improved energy harvesting.
Compact Design and Easy Installation
Thanks to its compact dimensions and lightweight construction, the SUN2000-4K-LB0 can be installed quickly and easily by a single technician, reducing installation time and costs.
Its elegant design and premium build quality make it a perfect fit for modern residential environments.
Advanced Monitoring and Connectivity
System monitoring is managed through the integrated WLAN connection, providing real-time access to performance data and system status.
Connectivity can be expanded through optional communication accessories: Huawei Smart Dongle WLAN FE 2.0, Huawei Smart Dongle 4G
These options enable remote monitoring and management through Huawei's intelligent energy platform.
Intelligent AFCI Safety Protection
The integrated AFCI (Arc Fault Circuit Interrupter) technology continuously monitors the system and detects DC arc faults up to 200 meters away.
In the event of an arc fault, the inverter automatically disconnects the circuit in less than 0.5 seconds, significantly reducing fire risks and enhancing overall system safety.
Built for Harsh Environments
Designed to operate reliably in demanding conditions, the SUN2000-4K-LB0 features:
- IP66 protection rating
- Resistance to dust, sand, corrosion, salt mist, and high-pressure water jets
- Operating temperature range from -25°C to +60°C
- Integrated protection against AC/DC surge voltages caused by lightning
These features ensure long-term durability and dependable operation in virtually any climate.
Battery-Ready for Greater Energy Independence
The Huawei SUN2000-4K-LB0 is designed for seamless integration with Huawei energy storage systems, allowing homeowners to add battery storage whenever desired.
By storing excess solar energy generated during the day, users can continue powering their homes during the evening or periods of low solar production, increasing self-consumption and reducing reliance on the grid.
Backup Guaranteed at All Times
Say goodbye to darkness: the optional whole-home backup solution automatically activates in the event of a power outage, ensuring a continuous and reliable power supply.
For single inverter installations connected exclusively via Wi-Fi (with the router located sufficiently close to the system), plant monitoring can be performed using the inverter's built-in wireless communication module, without the need to purchase an additional dongle.
Communication options can be expanded as follows:
Internet/Ethernet communication via the Huawei Smart Dongle WLAN-FE (Part No. 6856625)
4G/3G/2G mobile network communication via the Huawei Smart Dongle 4G (Part No. 6853066)
Important: Huawei Smart Dongles are optional accessories and must be purchased separately. They are not included with the inverter.
