Inverter Huawei SUN2000-30KTL-M3, 30kW on-grid three-phase

This device converts the current produced by the panels into alternating current, the one used by the machines, pumps and installations in a building, and delivers it on three phases. It is sized for company roofs, not for an ordinary house. It has eight separate inputs for the panel strings, which means that each group is tracked individually: if a string drops or fails, it is seen immediately in the app, without the need to search on the roof.

With 30.000 W of active power and 33.000 VA of apparent power, it supplies the daytime consumption of a workshop, a hall or a farm, reducing the bill during working hours. The 4 MPPT trackers and 8 strings allow the panels to be split over several roof slopes or over different orientations. The maximum efficiency of 98,7% means that the conversion losses are below 1,5%. The device weighs 43 kg and measures 640 x 530 x 270 mm, has IP66 protection and works between -25 and +60 degrees C, so it is wall-mounted, including outdoors. Maintenance comes down to the periodic checking of the connections and to keeping the cooling area clear.

Rated output current 43,3 A, maximum 47,9 A at 400 Vac; output voltage 230 / 400 / 480 Vac, 3W/N+PE, 50/60 Hz. DC: 1.100 V maximum voltage, 4 MPPT / 8 inputs, 27 A per MPPT (20 A per input), MPPT range 200-1.000 V, start-up voltage 200 V; weighted European efficiency 98,4%. Transformerless topology, intelligent air cooling, integrated AFCI, PID recovery, type II surge arresters on DC and AC, insulation resistance detection and I-V curve diagnosis. RS485 and MBUS communication, WLAN/Ethernet or 4G through Smart Dongle, FusionSolar integration; connection according to EN 50549-1 and C10/11.

Who it suits

Suitable for a hall, a warehouse or a farm with high consumption during the day and a roof that allows the installation of a field of approximately 30 kWp over several orientations.

Terms explained

• String (row of panels): A group of panels connected in series, as in a chain; the inverter can track eight such chains separately.
• PID recovery: A function that corrects at night a slow degradation of the panels caused by voltage, helping to preserve the production over time.
• I-V curve: An automatic test that measures the behaviour of each string and shows where the problem is, without climbing on the roof.

Technical specifications

Recommended applications

• Commercial and industrial roofs
• Production halls and warehouses
• Crop and livestock farms
• Self-consumption with grid compensation

Warranty

Standard manufacturer warranty 5 years, with the possibility of extension

Technical details

Specifications confirmed from the manufacturer's datasheet

Huawei SUN2000-30KTL-M3 is a three-phase on-grid 30 kW string inverter of the M3 family, dedicated to commercial and industrial rooftop applications. The rated active power is 30.000 W, and the maximum apparent power 33.000 VA. The rated output current is 43,3 A, and the maximum one 47,9 A at 400 Vac; the output voltage is 230 Vac / 400 Vac / 480 Vac, 3W/N+PE, at 50/60 Hz.
