Huawei SUN2000-330KTL-H1 — 300 kW grid PV inverter, 800 V

Description

Technical specifications

Photovoltaics for utility plants

Huawei SUN2000-330KTL-H1 is a three-phase grid-connected string inverter for utility photovoltaic plants and industrial energy projects. Rated output is 300 kW with a 330 kVA maximum. The system uses PV voltage up to 1500 V DC and an 800 V AC output connected through a dedicated power transformer.

Exact model output

Connection design uses 300 kW rated output, 330 kVA maximum apparent power and 238.2 A maximum AC current at 800 V. The model number is assessed together with these values. Maximum efficiency is 99.01% and European efficiency 98.8% per the current manual. Actual generation in kWh depends on location, modules, orientation and operation.

MPPTs and PV inputs

6 independent MPPTs serve 28 DC inputs with up to 65 A per MPPT. Startup voltage is 550 V, minimum operating voltage 500 V and operating range 500–1500 V. Full-load range is 930–1300 V with 1080 V rated DC voltage. Strings follow the exact model terminal plan; strings sharing an MPPT use matching module types and counts.

Operating environment

IP66 protection and a −25 to +60°C operating range support fixed outdoor installation. Relative humidity is 0–100% and operating altitude up to 5000 m with derating above 4000 m. Placement considers the temperature characteristic, airflow, access and installation clearances.

Dimensions and construction

Dimensions are 1048 ×732 ×395 mm and net weight is 112 kg per the current manual. Smart air cooling is combined with an appropriately designed supporting structure and service clearance. Site preparation considers handling, AC-terminal access and PV cable routing.

System configuration

The project combines designed PV strings, inverter, protected AC distribution, a dedicated power transformer and system monitoring. Output is designed as 800 V AC, 3L+PE, in the supported IT system for PV operation. Model groups are assigned to the appropriate separate transformer winding according to documentation. Power, protection, control and connection rules are engineered together.

Monitoring and communication

LED indicators, USB and the app support local commissioning and service. RS485 and MBUS connect the plant to system monitoring. Compatible SmartLogger and control infrastructure are selected for the project and firmware. MBUS forms part of the industrial transformer layout; communication routes and power cables receive the appropriate arrangement.

Protection and operating supervision

The model includes DC switches, anti-islanding, AC overcurrent and reverse DC polarity protection, PV-string supervision, insulation monitoring and residual-current monitoring. DC and AC surge protection are Type II. Protection settings and grid profile are coordinated with the plant design and connection conditions.

Protection and cable design

The reference three-phase breaker is 400 A rated at least 800 V AC. Copper AC conductors are 120–400 mm² for single-core and 120–240 mm² for multi-core cables; aluminum alloy or copper-clad aluminum conductors are 150–400 and 150–240 mm² respectively. 1500 V DC cable is 4–6 mm² with 5–7.8 mm diameter. AC lugs are M12 OT/DT and PE lugs M10 OT/DT. Reference PE cross-section is at least half the AC cross-section for the same conductor material; other combinations are designed for equivalent conductivity according to IEC60364-5-54.

Selection for an energy project

Selection separately evaluates 300 kW rated output, the 330 kVA maximum, string counts and currents, array area and transformer capacity. Energy generation in kWh depends on the designed array and site. Any storage is engineered as a separate compatible power and control section of the energy system.

Offer scope and documentation

The price covers the exact individual inverter model. PV modules, transformer, protection, cables, metering and monitoring are selected for the project. The public Markdown provides a detailed model profile including system relationships. Estimated delivery of 2–3 days is the seller’s estimate.
