Huawei Three-phase Inverter 330kW SUN2000L-330KTL-H1

Product Description

The Huawei SUN2000L-330KTL-H1 is a high-power three-phase inverter designed for large-scale photovoltaic plants that require maximum efficiency, advanced safety, and professional management. It operates at 1500 Vdc and offers an architecture with 6 MPPT trackers and up to 28 PV inputs, allowing for the design of long strings with current high-power modules and high currents, reducing mismatch losses and improving the project's LCOE. Its maximum efficiency reaches 99%, and its IP66 enclosure ensures reliable outdoor operation for years.

Main Features

• Power: 300 kW nominal AC and up to 330 kW maximum active power (330 kVA apparent).
• 1500 V PV Input: 6 independent MPPTs with 4/5/5/4/5/5 inputs (up to 28 strings in total).
• Current per MPPT: 65 A max.; Isc max. per MPPT 115 A; start voltage 550 V; MPPT range 500–1500 V.
• Output at 800 Vac (3W+PE), 50/60 Hz; THD <1% and adjustable power factor from 0.8 inductive to 0.8 capacitive.
• Advanced protections: AFCI, SSLD (intelligent string disconnection), SCLD (connector detection), SPD type II on DC and AC, RCMU, and insulation monitoring.
• Intelligent cooling “Smart Air Cooling”, operation from −25 °C to +60 °C and altitude up to 4000 m without derating.

Advantages or Benefits

• More kWh per area: 6 independent MPPTs with up to 28 inputs allow the generator to be divided by orientations and lengths, mitigating partial shading and mismatch.
• Leading efficiency (up to 99%) resulting in higher annual production and lower levelized cost of energy.
• Industrial-grade safety: arc detection and mitigation, string-level disconnection, and granular control reduce risks and speed up O&M interventions.
• Minimal OPEX: intelligent I-V curve diagnosis, string-level monitoring, and transformerless design facilitate maintenance and shorten downtime.
• Outdoor robustness: IP66 rating, C5-Medium anti-corrosion, and high-reliability ventilation for demanding climates.
• Digital integration: guided commissioning and remote monitoring with FusionSolar; RS485, MBUS, WLAN/APP, and USB communications for data management.

Purpose or Applications

Designed for large industrial rooftops, ground-mounted solar parks, agro-industry, logistics centers, and high-power energy communities. Its operation at 1500 V reduces cable sections and the number of strings, optimizing CAPEX and simplifying electrical works, especially when connection to medium voltage grids via transformer is required.

Technical Specifications

Compatibilities

Direct integration with the FusionSolar platform and APP for monitoring and commissioning. Compatible with SmartLogger for plants, MBUS/RS485 communications, and network accessories (Smart Dongle WLAN/Ethernet or 4G depending on the project). It does not have a battery interface or backup function.

In summary, the Huawei SUN2000L-330KTL-H1 delivers utility-scale power, 99% efficiency, and advanced safety with granular string management, maximizing energy and reducing operating costs in large photovoltaic installations.
