Goodwe Three-Phase Inverter GW250KN-HT 250kW HT1500V 6 MPPT

6 MPPT architecture with high current per tracker

The Goodwe GW250KN-HT 250kW HT1500V 6 MPPT Three-Phase Inverter offers the same 250 kW power at 800 Vac as the K version, but concentrates management in 6 MPPT trackers capable of supporting three strings each. This increases the current per tracker (up to 60 A) and simplifies field wiring, while maintaining a peak efficiency of 99% and IP66 protection rating. It incorporates intelligent string protection to isolate faulty strings and minimize losses, as well as advanced O&M tools such as string-level monitoring and I-V scanning.

Main features

• Nominal power: 250 kW AC at 800 Vac with adjustable PF 0.8 cap…0.8 ind; THD <3%.
• 6 MPPT, 3 strings per MPPT (18 total strings) with current per MPPT up to 60 A; max Isc 90 A.
• DC bus at 1500 V: MPPT range 500–1500 Vdc; Vmax 1500 V; Vstart 550 V.
• Max efficiency 99.0%, IP66 enclosure and operation −30…+60 °C with forced ventilation.
• Intelligent string protection: switching isolates the faulty string to maintain production.
• Advanced diagnostics with string-level reading and I-V curves for predictive O&M.

Advantages or benefits

• Less BOS and simplified wiring by grouping three strings per MPPT with high current limits.
• Service continuity: automatic isolation of faulty strings reduces impact on daily energy.
• Professional integration with SCADA/EMS via RS-485 (Modbus-RTU/SunSpec) and WiFi/4G options.
• Comprehensive safety: DC isolator, SPD T2 on DC/AC, RCMU, insulation detection and polarity protection.
• LCOE optimization: maximum efficiency, low night consumption and robust outdoor operation.

Purpose or applications

Designed for photovoltaic parks and large rooftops at 1500 Vdc with high-current strings (bifacial 182/210 mm, TOPCon, HJT). Its 800 Vac output facilitates coupling to MV transformer and grid connection for large-scale self-consumption or small utility-scale, with export control via external systems.

Technical specifications

Compatibilities

Compatible with PERC, TOPCon, HJT and bifacial modules (up to 15 A per string), 1500 Vdc combiner boxes with gPV fuses, SPD T2 and MPPT-level isolation, as well as SCADA/EMS via Modbus-RTU. Provide us with your store's internal links to add direct compatibilities.
