BOS optimal, rendements supérieurs, O&M intelligent, sûr et fiable, compatible réseau

Une nouvelle génération de puissance pour les grandes centrales PV

L’onduleur Smart String HUAWEI SUN2000-506KTL-H1/H3 est conçu pour les centrales solaires utility-scale, délivrant jusqu’à 506 kVA avec une efficacité de pointe ≥99 %. Équipé de six MPP trackers indépendants et d’un système de refroidissement hybride avancé, il convertit l’énergie solaire en énergie injectable sur le réseau tout en prenant en charge les dernières fonctionnalités Grid-Forming pour une exploitation stable et fiable, même dans les environnements les plus exigeants.

Key Features

Unmatched Efficiency

  • Max Efficiency of 99.1% and European Efficiency of 98.8% for superior energy conversion across the full load range.
  • 6 Independent MPP Trackers with up to 6 PV inputs per MPPT (36 strings total) for maximum design flexibility and optimal yield, even with mismatched or partially shaded arrays.
  • Wide MPPT Operating Voltage Range of 500 V to 1500 V to accommodate diverse plant layouts and module technologies.
  • Max DC Input Voltage of 1500 V unlocks longer strings, lower BOS costs, and improved system economics.

Advanced Design and Performance

Hybrid Cooling and Reliable Thermal Management

  • Hybrid Cooling System combining natural convection and forced air for higher power density and stable performance in harsh climates.
  • Self-Cleaning Fan (SSCF) with anti-icing function ensures uninterrupted operation in dusty, humid, or cold environments while reducing maintenance.
  • Operating temperature range: –25 °C to +60 °C, with full power output up to 4,000 m altitude.

Comprehensive Safety and Protection

  • String-Level Disconnection (SSLD) and Smart Connector-Level Detection (SCLD) for fast isolation of DC-side faults.
  • Type II Surge Protection on both AC and DC sides protects the inverter from lightning and grid transients.
  • DC reverse polarity protection, PV string fault detection, AC overcurrent protection, insulation resistance monitoring, and residual current detection for end-to-end electrical safety.
  • IP66 enclosure and C5-Medium anti-corrosion rating make it ideal for coastal, desert, and industrial environments.

Smart Monitoring and Easy Control

  • RS485 and MBUS Communication: Easily integrate the inverter with Huawei FusionSolar Smart PV Management System for real-time monitoring and control.
  • Smart IV Curve Diagnosis: Provides string-level monitoring for precise fault detection and rapid troubleshooting.
  • FusionSolar App: Simplify setup and management via the FusionSolar app, offering remote monitoring and configuration.

Smart Monitoring and Easy Control

  • MBUS Power Line Communication transmits data over the AC power cable, removing the need for additional communication wiring and simplifying plant cabling.
  • Smart I-V Curve Diagnosis enables string-level fault detection and proactive maintenance for lower O&M costs.
  • LED Status Indicators for fast on-site diagnostics, with full remote monitoring and management via the Huawei SmartLogger5000A and FusionSolar management system.
  • Three-Level Fault Recording (plant-level, array-level, and inverter-level) for in-depth analysis of grid events in standard COMTRADE 2013 format.

Grid-Forming Ready for the Modern Power Grid

The SUN2000-506KTL-H1/H3 supports Grid-Forming (GFM) operation, acting as a virtual synchronous generator (VSG) to enhance grid stability during frequency and voltage fluctuations.

  • PV Black Start capability provides commissioning power without an external grid or genset.
  • Primary frequency regulation, primary voltage regulation, and inertia response improve grid resilience in renewable-rich networks.
  • Power Oscillation Damping (POD) suppresses low-frequency oscillations from 0.1 Hz to 5 Hz.
  • Auto-Start with Reactive Power at Night for continuous reactive power support and automatic recovery after grid disturbances (SUN2000-506KTL-H1 with soft-start board).

Power your utility-scale solar projects with the high-efficiency, grid-forming-ready HUAWEI SUN2000-506KTL-H1 Smart String Inverter — built for the next generation of large PV plants.
