Huawei SUN2000-115KTL-M2 Inverter, 115kW on-grid three-phase

This inverter is the brain of a large photovoltaic plant: it converts the direct current collected from hundreds of panels into three-phase alternating current and feeds it into the grid. Being the most powerful model in its family, it allows a plant to be covered with fewer units, so fewer connection and maintenance points. Each group of panels is tracked separately, and an automatic test can scan the whole installation to quickly find the area that is not producing as much as it should.

The rated active power is 115,000 W, with 125,000 VA apparent power — the level of a solar park or an extended industrial roof. The maximum efficiency is 98.6% at 400 V and 98.8% on a 480 V grid, which matters a lot at this scale, where every tenth of a percent means real energy gained. The IP66 enclosure, of 1,035 x 700 x 365 mm and 93 kg, is fan-cooled and withstands -25...+60 degrees C, humidity 0-100% and altitudes of up to 4,000 m. The plug-in type DC connectors shorten the installation time in the field.

Rated output current 166.0 A at 400 V and 138.4 A at 480 V, with maximums of 182.3 A and 151.9 A respectively; frequency 50/60 Hz, THD below 3%; weighted European efficiency 98.4% at 400 V and 98.6% at 480 V. DC: 1,100 V maximum voltage, 10 MPPT / 20 string inputs, 30 A per MPPT and 20 A per input, maximum total DC current 300 A, MPPT range 200-1,000 V, start-up voltage 200 V. Transformerless topology, type II surge arresters on DC and AC, intelligent I-V curve diagnosis, individual management of each string. RS485, USB, MBUS and WLAN communication, with monitoring in the FusionSolar platform.

Who it suits

Suitable for ground-mounted solar parks and large industrial sites, especially where the internal grid works at 480 V and maximum efficiency is sought.

Terms explained

• Total DC current: The sum of the currents coming from all the panel strings; here the limit is 300 A and it determines how many panels can be connected.
• Humidity 0-100% RH: The unit works even in air completely saturated with moisture, as happens in lowland areas with fog or near water.
• Plug-in connector: Plugs that couple by pressing, without screws, which shortens the installation and reduces the risk of a loose contact.

Technical details

Specifications confirmed from the manufacturer's datasheet

Huawei SUN2000-115KTL-M2 is a 115 kW three-phase on-grid string inverter, the most powerful model in the KTL-M2 family, intended for commercial, industrial and utility-type photovoltaic plants. The rated active power is 115,000 W, and the maximum apparent power 125,000 VA. The rated output current is 166.0 A at 400 V and 138.4 A at 480 V, with maximum values of 182.3 A and 151.9 A respectively; grid frequency 50/60 Hz and THD below 3%. The maximum efficiency reaches 98.6% at 400 V and 98.8% at 480 V, with a weighted European efficiency of 98.4% and 98.6% respectively.

The DC side accepts a maximum voltage of 1,100 V, with 10 independent MPPT trackers and 20 string inputs, 30 A maximum current per MPPT and 20 A per input, maximum total DC current 300 A. The MPPT operating range is 200-1,000 V, with a start-up voltage of 200 V. Each string is managed individually, and the intelligent I-V curve diagnosis allows a quick scan of the entire plant.

The IP66 enclosure with forced fan cooling measures 1,035 x 700 x 365 mm and weighs 93 kg, working at -25...+60 C, humidity 0-100% RH and a maximum altitude of 4,000 m. Transformerless topology, with type II surge arresters on DC and AC and plug-in type DC connectors. RS485, USB, MBUS and WLAN communication, with monitoring in the FusionSolar platform.
