Goodwe GW80K-SMT

The GoodWe GW80K‑SMT is a three‑phase string inverter for commercial and industrial photovoltaic systems with rated power up to 80kW. With six independently operating MPP trackers and a wide MPPT voltage range from 180to1000V, the device is suitable for complex rooftop and ground‑mounted layouts with varying string lengths. The maximum DC input voltage of 1100V as well as an input current of up to 21A per string support the use of modern high‑performance modules. The option of DC oversizing up to 150% allows for high specific generator power. Thanks to IP66 protection, integrated protective functions and an active fan‑cooling concept, the inverter is designed for continuous outdoor operation and high ambient temperatures.

• TechnologyThe inverter uses a transformerless, three‑phase string topology with a high efficiency of up to 98.6%. Six MPP trackers, each with two string inputs, enable fine‑grained adaptation to different module fields and reduce yield losses in the event of partial shading. The high permissible short‑circuit current of 52.5A per MPPT ensures that even powerful module strings can be operated within the electrical limits. The maximum AC apparent power of 88kVA provides reserves for temporary overproduction and grid‑side requirements.
  
  Electrical performance data
  • 80kW rated AC power with three‑phase grid feed‑in and adjustable power factor
  • 1100V maximum DC system voltage for long strings and reduced cable losses
  • Six MPP trackers for flexible generator design and higher yields
  • 150% DC oversizing for optimal module utilization
• ConnectivitySeveral communication interfaces are available for system integration, including RS485 as well as optional WiFi‑, LAN‑ or 4G modules. Support of Modbus‑RTU enables integration into higher‑level monitoring, control or energy‑management systems. Via these interfaces, operating data can be read out, power limitations configured and grid‑support functions implemented, which is particularly relevant for larger commercial installations and clustered systems.
  
  Communication & Monitoring
  • RS485 interface for stable, wired system communication
  • Optional WiFi, LAN or 4G for location‑independent monitoring
  • Modbus‑RTU for integration into external control systems
  • Remote monitoring and parameterization of critical operating settings
• WarrantyThe GW80K‑SMT is supplied with the manufacturer’s standard warranty, which secures the inverter against material and manufacturing defects for several years. For projects with longer operating horizons, optional warranty extensions can be used to reduce investment risk over the planned service life. Warranty handling is designed for professional use in C&I systems.
  
  Warranty
  • Standard manufacturer product warranty
  • Optional extensions for long‑term project security
  • Designed for continuous C&I operation
• SustainabilityThanks to its high efficiency and support of high DC oversizing, the inverter contributes to efficient utilization of the installed module capacity. Low self‑losses and a night consumption of less than 1W reduce system‑related energy demand. WEEE registration ensures regulated take‑back and disposal at the end of the product life cycle.
  
  Resource & energy efficiency
  • High efficiency to minimize conversion losses
  • Very low self‑consumption in standby operation
  • WEEE‑compliant disposal and recycling
• QualityThe enclosure with IP66 protection reliably protects the power electronics against dust, moisture and severe environmental influences. The operating temperature range from −30to+60°C and the intelligent fan‑cooling concept enable stable operation even at high power densities. Integrated protective functions such as insulation monitoring, TypeII surge protection on the DC and AC sides as well as an optional AFCI function increase operational safety.
  
  Robustness & protection
  • IP66 enclosure for outdoor and industrial environments
  • Comprehensive integrated electrical protection mechanisms
  • Designed for high ambient temperatures
• ExpandabilityThe modular design with six MPPTs facilitates later adjustments to the generator structure. Optional accessories such as data loggers, remote shutdown or rapid‑shutdown functions enable retrofitting of additional safety and monitoring requirements. This makes the inverter suitable for scalable system concepts and expansions during ongoing operation.
  
  System expansion
  • Retrofit‑capable communication and safety modules
  • Flexible adaptation to changed generator layouts
  • Integration into growing C&I systems
