Huawei SUN2000-3K-LB0

The Huawei SUN2000‑3K‑LB0 is a single-phase hybrid inverter for smaller PV systems with optional storage connection. With a rated AC power of 3,000 VA and two MPP trackers, it is suitable for flexible string layouts and common module configurations up to 600 V DC. The hybrid topology allows the direct coupling of high-voltage storage systems and forms the basis for self-consumption and backup concepts. The compact design with a device weight of 15 kg supports easy wall mounting indoors and outdoors. Protection functions on both the DC and AC sides, as well as the robust design with a high protection rating, are intended for long-term operation in decentralized energy systems. Through integration into the Huawei ecosystem, the inverter can be incorporated into tiered monitoring, optimization, and energy management concepts.

• TechnologyThe SUN2000‑3K‑LB0 operates as a single-phase string hybrid inverter with two independently operating MPP trackers. The DC input voltage of up to 600 V enables the connection of standard module strings while maintaining a wide MPPT operating range. The hybrid architecture allows PV generation, battery charging, and grid supply to be controlled within a single device. This reduces the need for external components, especially in systems with self-consumption optimization. The single-phase feed-in makes the device ideal for smaller systems in residential and commercial applications where the grid connection point and load profile are designed for single-phase operation.
  
  Power electronics
  • Two MPP trackers allow different string orientations and reduce yield losses in cases of partial shading
  • Hybrid topology combines PV feed-in, battery interface, and grid management in one device
  • Single-phase grid connection simplifies integration where connection capacity is limited
  • 600 V DC design supports compact string lengths with common module types
• ConnectivityFor system integration, the inverter provides a serial RS485 interface as well as wireless and network options. WLAN is intended for local and cloud-based monitoring, while Ethernet is implemented via optional dongles. The interfaces enable connection to higher-level monitoring platforms and energy management systems within the Huawei ecosystem. For installers, it is relevant that configuration, commissioning, and diagnostics can be carried out centrally without necessarily requiring additional measurement or gateway components.
  
  Interfaces & Monitoring
  • RS485 for stable communication with meters, storage systems, and management systems
  • WLAN for commissioning, remote monitoring, and service access
  • Ethernet connection via optional accessories for fixed network integration
  • Compatible with central monitoring and energy management platforms
• WarrantyThe SUN2000‑3K‑LB0 is subject to the manufacturer-defined standard product warranty for inverters in this series. It covers material and manufacturing defects within the intended scope of use. For project planning and operation, it is relevant that warranty conditions and possible extensions are governed by the manufacturer and handled via defined service processes. The clear classification within an established product portfolio facilitates long-term maintenance and spare parts strategies.
  
  Manufacturer services
  • Standard warranty according to the Huawei inverter segment
  • Centralized service and RMA structures via the manufacturer
  • Warranty extensions regulated by the manufacturer and dependent on the system
  • Clear distinction from accessories and storage components
• SustainabilityThe SUN2000‑3K‑LB0 is designed for durable operation with high energy efficiency and reduced material intensity. The compact design and comparatively low weight reduce transport and installation effort. At the same time, the hybrid function enables targeted self-consumption of PV energy, which reduces grid feed-in and minimizes system losses. Manufacturer recycling and take-back programs support the material recovery of electronic components.
  
  Ecological aspects
