The Huawei SUN2000-330KTL-H1 is a string inverter specifically designed for commercial, industrial (C&I) and utility-scale photovoltaic systems. Combining high conversion efficiency, six independent MPPTs and advanced safety and monitoring functions, it is an ideal solution for installers, designers and EPC contractors developing large-scale solar projects.
As the commercial and industrial PV market continues to grow, maximising energy yield while reducing operational costs has become a key priority.
The Huawei SUN2000-330KTL-H1 has been engineered to deliver high performance, greater design flexibility and long-term reliability, making it well suited to demanding MW-scale installations.
Key features of the Huawei SUN2000-330KTL-H1
With a rated active power of 300 kW and a maximum apparent power of 330 kVA, the Huawei SUN2000-330KTL-H1 is optimised for three-phase systems with a nominal output voltage of 800 V.
Its maximum efficiency of 99% and European efficiency of 98.8% ensure outstanding energy conversion performance, helping to maximise energy production and improve project profitability.
The inverter features:
- 6 independent MPPTs;
- maximum input current of 65 A per MPPT;
- short-circuit current of 115 A per MPPT;
- 28 DC inputs;
- maximum DC input voltage of 1,500 V.
These specifications provide greater design flexibility, enabling long PV strings and compatibility with the latest generation of high-current, high-power PV modules.
Why choose the SUN2000-330KTL-H1 for utility-scale PV projects
The continuous evolution of high-power photovoltaic modules requires inverters capable of handling higher input currents without compromising system performance.
Thanks to its six independent MPPTs, 28 DC inputs and 1,500 V DC architecture, the Huawei SUN2000-330KTL-H1 allows designers to optimise string layouts even on complex, large-scale installations.
The ability to support next-generation PV modules also helps maximise energy yield, minimise mismatch losses and reduce the Levelised Cost of Energy (LCOE), making it an excellent choice for utility-scale and large commercial solar projects.
Advanced safety features
Safety and operational continuity are essential requirements for MW-scale photovoltaic installations. The Huawei SUN2000-330KTL-H1 integrates several advanced protection features designed to improve system reliability and minimise downtime.
Key safety functions include:
- Smart String-Level Disconnection (SSLD) and Smart Connector-Level Detection (SCLD) for continuous string monitoring and automatic fault response;
- Type II surge protection devices (SPD) on both the DC and AC sides;
- IP66 enclosure protection, ensuring reliable operation even in harsh outdoor environments.
These integrated protection systems help reduce operational risks while improving plant availability throughout its lifetime.
Integration with Huawei FusionSolar
The SUN2000-330KTL-H1 supports MBUS, RS485 and Wi-Fi communication protocols and integrates seamlessly with the Huawei FusionSolar platform through the SmartLogger.
FusionSolar provides centralised monitoring and advanced plant management features, including:
- string-level monitoring;
- centralised inverter management;
- real-time performance analysis;
- alarm management;
- advanced reporting tools.
This integration enables installers and plant operators to monitor large photovoltaic systems efficiently while simplifying daily asset management.
Intelligent diagnostics for lower O&M costs
One of the key advantages of the Huawei SUN2000-330KTL-H1 is its Intelligent IV Curve Diagnosis, which continuously analyses string performance and detects potential issues before they affect energy production.
This predictive diagnostic capability allows operators to:
- quickly identify performance losses;
- schedule predictive maintenance activities;
- reduce Operation & Maintenance (O&M) costs;
- maximise long-term system availability and operational efficiency.
