Huawei SUN2000-6KTL-M1 three-phase hybrid inverter, 6kW

The inverter is the device that makes the energy from the roof usable in the house: it transforms the direct current of the panels into alternating current and directs it to the loads, to the battery or to the grid. The basic idea is self-consumption — you use your own energy instead of buying it, and the surplus you store or send into the grid. The model is installed on a three-phase connection and permanently monitors the direct current cables, with arc fault detection assisted by artificial intelligence.

The 6,000 W rated cover several large loads at the same time in a spacious house or a small headquarters, and on the panel side it accepts up to 9,000 Wp, that is approximately 1.5 times the output power. The two MPPTs support two strings with different orientations, tracked independently. Connected to a LUNA2000 battery of 5-30 kWh, the inverter charges with up to 10,000 W and discharges with up to 6,600 W, and with the Backup Box-B1 it maintains 3,300 VA at the essential loads during a power outage. At 17 kg, 525 x 470 x 146.5 mm, IP65 enclosure, cooling by natural convection and night consumption below 5.5 W, it can be installed outdoors, makes no noise and requires no periodic maintenance.

6,000 W rated active power and 6,600 VA apparent on a 220/380 V or 230/400 V grid (3W/N+PE), 50/60 Hz, 10.1 A maximum output current, THD below 3%, power factor adjustable 0.8 capacitive...0.8 inductive, maximum efficiency 98.6% / European 97.7%. DC: 2 MPPT with one string each, 1,100 V maximum, range 140-980 V (nominal 600 V, start-up 200 V), 11 A/MPPT and 15 A short circuit, 9,000 Wp recommended (up to 20,000 Wp with SUN2000-450W-P optimisers). LUNA2000 / Smart String ESS battery 5-30 kWh, 600-980 V, 16.7 A, 10,000 W charging / 6,600 W discharging. AFCI protections, insulation and residual current monitoring, type II SPD on DC and AC, anti-islanding, PID recovery; -25...+60 °C; EN/IEC 62109-1/-2, IEC 62116, VDE-AR-N 4105, EN 50438, CEI 0-21, G98/G99; RS485 and Smart Dongle-WLAN-FE, 4G optional.

Who it suits

Suitable for a large house, a small guesthouse or a company headquarters with a three-phase connection and a 6-9 kWp system, with high consumption and the wish for storage.

Terms explained

• Self-consumption: The energy produced by the panels is used first in the building and only the surplus goes into the grid or into the battery.
• Adjustable power factor: The inverter can adjust the way it delivers energy into the grid, at the request of the distribution operator, without stopping production.
• Smart Dongle: The small communication module that connects the inverter to the internet through Wi-Fi, network cable or 4G, so that you can see the production in the app.
