GoodWe HT 1500V 250 kW Three-Phase Solar Inverter GW250K-HT

High-power three-phase inverter for utility-scale installations that combines industry-leading performance, intelligent string-level diagnostics, and professional communications. Its 1500 Vdc topology with 12 MPPT (2 strings per MPPT) maximizes output with high-current modules and reduces line losses, while the IP66 rating and outdoor-ready design simplify installation and O&M.

Main Features

• AC Nominal Power: 250 kW (three-phase 800 V, 3L/PE).
• PV Architecture: 12 independent MPPTs, 2 strings per MPPT (24 inputs).
• DC Level: 1500 Vdc; typical MPPT range 500–1500 V; startup ~550 V.
• Current per MPPT: up to 30 A (max Isc per MPPT up to 50 A).
• Efficiency: max. 99.0%; European reference efficiency ~98.5%.
• Environmental Protection: IP66 for outdoor/indoor protected installation.
• Cooling: intelligent ventilation with thermal control.
• Nighttime Self-Consumption: < 18 W to minimize off-service losses.
• Connectivity and Control: RS-485 and PLC; Modbus RTU protocol; app/portal for commissioning and monitoring.
• O&M Functions: string monitoring, I-V diagnostics, remote adjustments and updates.

Safety and Protections

• Anti-islanding, insulation monitoring, RCMU, and reverse polarity protection.
• Type II surge protection on DC/AC (Type I optional depending on project).
• Integrated DC disconnector and string-level fault management for proactive maintenance.

Electrical Integration

• AC Connection: OT/DT terminals (up to 300 mm²).
• DC Connection: MC4-Evo2 connectors (4–6 mm²).
• Compatible with high-current bifacial modules (182/210 mm).

Dimensions and Weight

• Dimensions (W × H × D): 1091 × 678 × 341 mm.
• Weight: 111 kg.

Project Advantages

• Higher annual yield with 12 MPPTs and adaptation to heterogeneous rooftops/fields.
• Lower BOS cost by operating at 1500 Vdc and reducing cable sizes and voltage drops.
• Optimized O&M with string-level diagnostics, remote updates, and integrated PLC.
• Robust outdoor deployment thanks to IP66 and industrial-grade construction.

Installation Best Practices

• Design strings within the MPPT voltage/current limits.
• Complete protections and disconnection according to regulations and grid operator requirements.
• Ensure ventilation and perimeter space for thermal dissipation.
• Commission with app/portal, verify RS-485/PLC communications, and register on the platform.

Designed for ground-mounted plants and large rooftops, this 250 kW inverter reduces CAPEX and OPEX by combining 99% efficiency, 1500 V electronics, and an O&M toolset that shortens commissioning and field diagnostics times.
