Huawei SUN2000-36KTL-M3 inverter, 36kW on-grid three-phase

The inverter is the device that takes the direct current from the panels and converts it into the alternating current used by the equipment in the building, on three phases. This model is designed for industrial installations, where a few hundred panels are mounted and it is important to know quickly if a group has stopped producing. Each of the eight strings is monitored separately, and the device can run a diagnostic test on its own.

It delivers 36,000 W of active power and 40,000 VA of apparent power, meaning it can cover the daytime consumption of a production unit or a logistics centre. The 4 MPPT trackers split the panel field into independent zones, useful when the roof has several pitches or partial shading at different hours. The maximum efficiency of 98.7% and the European weighted efficiency of 98.4% describe how much of the panels' energy actually reaches the installation. The box is 640 x 530 x 270 mm and 43 kg, with IP66 protection, and it operates between -25 and +60 degrees C — wall mounting, including outdoors, with free space around it for cooling.

Rated output current 52.0 A, maximum 58.0 A at 400 Vac; output voltage 230 / 400 / 480 Vac, 3W/N+PE, 50/60 Hz. DC: maximum voltage 1,100 V, 4 MPPT / 8 inputs, 27 A per MPPT and 20 A per input, MPPT range 200-1,000 V, start-up voltage 200 V. Transformerless design, intelligent air cooling, integrated AFCI, PID recovery, type II surge arresters on DC and AC, insulation resistance detection, intelligent I-V curve diagnosis. RS485 and MBUS communication, WLAN/Ethernet or 4G through Smart Dongle, FusionSolar integration; grid connection according to EN 50549-1 and C10/11.

Who it suits

Suitable for a production unit or a warehouse with a large roof and constant consumption during the day, where a photovoltaic field of around 36 kWp is installed.

Terms explained

• Apparent power (VA): The total power the device can deliver into the grid, including the part used to support the voltage, not only the energy actually consumed.
• Transformerless: A lighter and more efficient design, without the heavy isolation coil, which explains the low weight for this power level.
• Type II surge arrester: A protection component that takes the voltage peaks from indirect lightning strikes and diverts them to earth.

Technical specifications

Recommended applications

• PV installations on industrial roofs
• Logistics centres and warehouses
• Production and processing units
• High-power self-consumption projects

Warranty

Standard manufacturer warranty 5 years, with the possibility of extension

Technical details

Specifications confirmed from the manufacturer's datasheet

Huawei SUN2000-36KTL-M3 is a 36 kW on-grid three-phase string inverter from the M3 family, designed for commercial and industrial photovoltaic installations. The rated active power is 36,000 W and the maximum apparent power 40,000 VA. The rated output current is 52.0 A and the maximum 58.0 A at 400 Vac; the output voltage is 230 Vac / 400 Vac / 480 Vac, 3W/N+PE, at 50/60 Hz.

On the DC side it accepts a maximum voltage of 1,100 V and has 4 MPPT trackers with 8 string inputs, with 27 A maximum current per MPPT (20 A per input), MPPT operating range 200-1,000 V and start-up voltage 200 V. Maximum efficiency is 98.7% and the European weighted efficiency 98.4%. The 8 strings are monitored individually, which simplifies the rapid identification of faults.
