Huawei SUN2000-100KTL-M2 AFCI Inverter, 100kW on-grid three-phase

It is the central device of a large photovoltaic plant: it takes the direct current from hundreds of panels and converts it into three-phase alternating current, ready to be used or delivered into the grid. It has ten independent tracking circuits and twenty inputs, which means the installation can be divided into many zones, each managed separately. The arc fault detection system (AFCI) shuts the installation down if a spark appears at a loosened contact, an important protection on a large scale.

The rated active power is 100,000 W, and the maximum apparent power 110,000 VA — the level of an industrial roof plant or of a medium-power ground-mounted park. The maximum efficiency is 98.6% at 400 V and rises to 98.8% on a 480 V grid, and at night the device consumes about 3.5 W. The IP66 enclosure, of 1,035 x 700 x 365 mm and 93 kg, is mounted outdoors and works between -25 and +60 degrees C, up to 4,000 m altitude. Each string can be intelligently disconnected, and the automatic diagnosis scans the installation and shows where the problem is, which greatly shortens on-site interventions.

Output voltage 380 / 400 / 480 V, 3W+(N)+PE, 50/60 Hz; 144.4 A rated current at 400 V, respectively 120.3 A rated and 133.7 A maximum at 480 V; THD under 3%, adjustable power factor 0.8 capacitive - 0.8 inductive; European efficiency 98.4% at 400 V and 98.6% at 480 V. DC: 1,100 V maximum voltage, 10 MPPTs / 20 string inputs, 30 A per MPPT (20 A per input), 40 A short-circuit current per MPPT, MPPT range 200-1,000 V, rated input voltage 600 V at 400 Vac and 720 V at 480 Vac. Smart Air Cooling, type II surge arresters on DC and AC, I-V diagnosis. RS485, USB, MBUS and WLAN communication. Standards: EN/IEC 62109-1/-2, EN 50530, IEC 62116, IEC 61727; grid connection VDE-AR-N 4105, VDE-AR-N 4110, EN 50549-1/-2, RD 1699, C10/11.

Who it suits

Suited to commercial or industrial photovoltaic plants or ground-mounted parks of the order of hundreds of kW, where the installation is divided into many zones and string-level monitoring is required.

Terms explained

• Endurance at 4,000 m: The device can also operate at high altitude, where the rarefied air cools the electronic components less easily.
• String-level disconnection: The possibility of electrically shutting down a single group of panels, without taking the whole plant out of service.
• Adjustable power factor: The inverter's ability to help stabilise the grid voltage, a frequent requirement of the distribution operator.

Technical specifications

Recommended applications
