SUN2000-330KTL-H1 – A high-capacity 330 kW string inverter solution for utility-scale solar projects. The device features a maximum efficiency of $\ge$ 99.0%, integrated Smart String-Level Disconnect (SSLD), and high-speed MBUS communication, optimizing investment return throughout the project lifecycle.
Product Description
The SUN2000-330KTL-H1 is Huawei’s next-generation smart string inverter, specifically designed to optimize costs and energy yield for utility-scale solar power plants. By eliminating the internal transformer, it reduces the weight to 112 kg while maintaining reliable and safe operation under harsh environmental conditions.
Key features
-
High Energy Yield: Achieves a maximum efficiency of up to ≥ 99.0% (European efficiency ≥ 98.8%), maximizing green energy extraction from the PV array.
-
Smart String-Level Disconnect (SSLD): Automatically detects and disconnects faulty strings actively, preventing reverse current and protecting the entire PV array.
-
Smart Connector-Level Detection (SCLD): Automatically monitors temperatures at DC connectors, providing early warnings to eliminate over-temperature fire risks.
-
Online I-V Curve Diagnosis: Compatible with Huawei management software, enabling remote scanning of all strings with a single click and fault identification accuracy of $\ge$ 95%.
-
Smart Self-Cleaning Fan (SSFC): Integrated smart air cooling system featuring a self-cleaning fan function, optimizing heat dissipation for continuous operation across a temperature range of -30°C to +60°C.
Why Choose the SUN2000-330KTL-H1?
- Multiple MPPT Architecture: Optimizes energy yield, minimizing losses caused by mismatch or shading between strings.
- High Current Support: Maximum current per MPPT reaches 65A with a 115A short-circuit current, supporting high-power, next-generation PV modules on the market.
- Reliable MBUS Communication: Supports signal transmission directly over AC power cables, eliminating the cost of separate communication cabling for the project.
- Comprehensive Surge Protection: Equipped with Type II surge protection devices (SPDs) for both AC and DC sides, protecting internal circuits and components from sudden electrical surges.
- Exceptional Environmental Resistance: IP66 protection rating ensures absolute dustproof and waterproof capabilities, combined with C5-Medium anti-corrosion protection technology for reliable operation in coastal areas or floating solar projects.
- Simplified O&M Infrastructure: Supports easy on-site configuration, testing, and firmware updates via USB and mobile app connectivity.
