Huawei SUN2000-17KTL-M5 inverter, 17kW on-grid three-phase

The inverter is the part that makes the panels' energy usable: it converts direct current into alternating current and sends it into the building's installation. Being an on-grid model, it works together with the grid and covers consumption in real time, without a battery — suitable where the activity takes place during the day, when the sun produces. Electric arc detection assisted by artificial intelligence stops the installation when a hidden spark appears on the direct current cables.

With 17,000 W of rated power it covers the simultaneous consumption of a small hall or an office, and on the panel side it accepts up to 25,500 Wp, that is about 1.5 times the output power. The four string connections are split two per MPPT, so the roof can be organised over several orientations without losses between groups. The device weighs 21 kg, measures 546 x 460 x 228 mm, works between -25 and +60 °C and up to 4,000 m altitude. Cooling is fan-based, so it is slightly audible in operation and requires the grilles to be cleaned of dust; production monitoring is done in the FusionSolar platform.

17,000 W rated active power, 18,700 VA apparent, at 220/380 V, 230/400 V or 239.6/415 V (3W+N+PE), 50/60 Hz, 27.1 A maximum output current at 400 V, THD below 3%, power factor adjustable 0.8 capacitive...0.8 inductive, maximum efficiency 98.4% / European 98.1%. DC: 2 MPPT and 4 string connections (maximum 2 per MPPT), 1,100 V maximum voltage, MPPT range 200-1,000 V (nominal 600 V, start-up 200 V), full-load MPPT range 440-800 V, 30 A/MPPT with two strings (20 A with a single string), 40 A short circuit, 25,500 Wp recommended (up to 40,000 Wp with SUN2000-450W-P optimisers). AI-assisted AFCI, string fault detection, residual current monitoring, type II SPD on DC and class II on AC, anti-islanding, AC overcurrent and DC reverse polarity protection, PID recovery; IP66 enclosure with fan cooling, 21 kg, 546 x 460 x 228 mm; RS485 and Smart Dongle-WLAN-FE, 4G optional; compliant with EN/IEC 62109-1/-2, VDE-AR-N 4105 and 4110, EN 50549, CEI 0-21, CEI 0-16, G99, IEC 61727/62116.

Who it suits

Suitable for a hall, a commercial space or a company office with a three-phase connection, consumption concentrated during the day and a roof that can take 17-25 kWp.

Terms explained

• On-grid: The inverter works only together with the grid: it covers consumption in real time and sends the surplus into the grid, without storing energy.
• Fan cooling: The device has fans that remove the heat, so it is slightly audible in operation, and the grilles must be cleaned of dust periodically.
• SPD (surge arrester): The component that takes the voltage peaks arising from atmospheric discharges and protects the inverter's electronics.

Technical specifications

Recommended applications

• SMEs and office buildings
• Commercial self-consumption with grid injection

Warranty

10 years standard in Europe (Huawei Residential Smart PV policy), optionally extendable
