Goodwe GW25K-MT Three-Phase Inverter 25kW SMT 3 MPPT

Product description

The Goodwe GW25K-MT 25kW SMT 3 MPPT Three-Phase Inverter belongs to GoodWe's SMT commercial series, designed to maximize production on medium-power industrial and commercial rooftops. It integrates three MPPT trackers with two inputs each, allowing for six strings in total and precise string management. Its high efficiency (up to 98.7–98.8%), IP65 enclosure, and advanced communications make it a reliable, powerful inverter ready to operate in demanding conditions.

Main features

• Nominal AC power: 25 kW and up to 27.5 kW maximum output (10% AC overload).
• 3 MPPT with 2 strings per MPPT (6 strings total); max. DC voltage 1100 V; MPPT range 200–950 V; startup 180 V.
• Current per MPPT: up to 25 A (I_sc max. per MPPT 31.3 A), suitable for high-current half-cut and bifacial modules.
• Max. efficiency 98.7–98.8% and European yield > 98.4%.
• Fuse-free input design with string-level current monitoring and integrated DC disconnector.
• IP65 protection, type III SPD on DC/AC (type II SPD recommended in panels), and optional AFCI.
• RS-485/Wi-Fi/PLC communications (SEMS portal) and Modbus-RTU (SunSpec) compatibility.

Advantages or benefits

• Design flexibility: three MPPT with two inputs per tracker to group orientations and reduce losses from partial shading.
• Greater availability: robust electronics with solid capacitor, high-durability fan cooling, and night self-consumption < 1 W.
• Optimized total cost: “fuse-free” design reduces maintenance, and 30% DC oversizing allows better use of low irradiance hours.
• Enhanced safety: anti-islanding, residual current monitor, insulation detection, overvoltage and overcurrent protection, and AFCI option.
• Professional monitoring: SEMS portal with reactive power control and dynamic export limitation via three-phase meter.

Purpose or applications

Ideal for commercial and light industrial self-consumption on 400 V three-phase grids (3L/N/PE or 3L/PE): warehouses, supermarkets, workshops, photovoltaic car parks, and buildings with multiple collection areas. Its string format facilitates installation on existing roofs and minimizes service interruptions.

Technical specifications

Compatibilities

Compatible with GoodWe three-phase meter (DTSD/GM) for zero export and consumption monitoring. Recommended DC boxes 3×2 with 15–20 A gPV fuses per string, disconnectors ≥ 25–32 A per MPPT, and type II SPD. On AC side, three-phase panel of 63 A with type A/B residual current protection as per regulations and type II SPD.

Goodwe GW25K-MT 25kW SMT 3 MPPT Three-Phase Inverter provides power, flexibility, and safety for commercial projects seeking maximum performance with controlled costs.
