Huawei SUN2000-5KTL-M1

The Huawei SUN2000‑5KTL‑M1 is a three-phase hybrid string inverter for grid-connected PV systems in the small power range. The AC nominal power of 5kVA in combination with two MPP trackers enables flexible string design even for partially shaded roof areas. With a maximum DC voltage of 1,100V, modern module concepts with high string voltages can be efficiently integrated. The inverter is designed as “battery-ready” and prepared for coupling with Huawei storage systems. Integrated safety functions such as arc fault detection increase system and fire safety. The compact housing with a high protection rating supports outdoor installation, while the comparatively low weight allows single-person installation. Typical applications include residential buildings and smaller commercial applications with a three-phase grid connection.

• TechnologyThe hybrid string topology used combines high conversion efficiency with system-side flexibility. Two independently operating MPP trackers allow the connection of differently oriented module arrays and reduce yield losses caused by shading. The design for a maximum PV generator power above the AC nominal power supports intentional DC oversizing for better system utilization. With a maximum efficiency of 98.4% and high European efficiency, the inverter operates stably even in partial load conditions. The three-phase grid feed-in ensures symmetrical load distribution and meets common grid connection requirements in the residential sector.
  
  Core technological data
  • Two MPP trackers for flexible string concepts in complex roof geometries
  • Maximum DC voltage of 1,100V for the use of modern high-voltage modules
  • High efficiency for low conversion losses in continuous operation
• ConnectivityFor monitoring and system integration, the inverter provides several communication interfaces. RS485 is integrated as standard and serves as a stable basis for connecting meters, energy management components, or optimizers. Ethernet, WLAN, or cellular connections can be implemented via optional smart dongles, allowing various system topologies and locations to be covered. Integration into the FusionSolar ecosystem enables centralized monitoring, remote maintenance, and parameter adjustments. For installers, this means simplified commissioning as well as reduced service effort over the entire system lifecycle.
  
  Interfaces and monitoring
  • RS485 as a robust connection for meters, storage, and system components
  • Ethernet, WLAN, or 4G realizable via optional smart dongles
  • Central monitoring and parameterization via the FusionSolar platform
• WarrantyHuawei equips the SUN2000‑5KTL‑M1 with a manufacturer’s standard product warranty covering basic operational reliability. Relevant protection functions such as DC and AC surge protection, residual current monitoring, and AI-supported arc fault detection are integral parts of the device. These functions support compliant operation and increase safety during installation and operation. For projects with higher requirements in terms of availability and runtime, the warranty concept can be supplemented with optional extensions, allowing economic risk to be managed over longer operating periods.
  
  Warranty and protection concept
  • Integrated protection functions reduce failure and fire risks
  • Standard manufacturer warranty as a basis for predictable operating periods
• SustainabilityIn product design, Huawei clearly emphasizes resource efficiency throughout the entire lifecycle. Reduced dimensions and a compact housing concept lower material usage and facilitate logistics and installation. Packaging is predominantly fiber-based and optimized for low volume. In addition, the manufacturer operates a global recycling program for electronic components, enabling the recovery of valuable raw materials. For planners and EPCs, this supports sustainable project concepts and facilitates integration into environmental tendering and documentation requirements.
  
  Sustainability aspects
  • Optimized housing concept to reduce material and transport effort
  • Fiber-based packaging materials for simplified disposal
  • Recycling programs for recovering electronic raw materials
• QualityThe SUN2000‑5KTL‑M1 meets high quality requirements in terms of mechanical design and electrical safety. The IP65-rated enclosure is suitable for permanent outdoor use and reliably protects against dust and water jets. Passive cooling reduces moving components and contributes to a long service life. With a weight of around 17kg, the device can be installed efficiently without compromising mechanical stability. This combination supports low-maintenance operation even under changing environmental conditions.
  
  Build and operational quality
  • Robust IP65 enclosure for protected outdoor operation
  • Passive cooling concept to reduce wear
• ExpandabilityThe system architecture of the inverter is consistently designed for expandability. Battery readiness allows for later retrofitting with Huawei storage systems without replacing the inverter. In addition, the system can be expanded via smart module controllers and optimizers to implement module monitoring and yield optimization at string or module level. In three-phase backup concepts, additional components such as backup boxes and energy management units can be integrated. This facilitates step-by-step adaptation to increasing self-consumption or autonomy requirements.
  
  System extensions
  • Battery-ready design for later storage integration
  • Compatibility with optimizers and energy management modules
  • Integration into three-phase backup and emergency power concepts
