Huawei SUN2000-15KTL-M5 Inverter, 15kW on-grid three-phase

The inverter takes the direct current of the panels and converts it into alternating current, which the building's installation can use immediately. It is an on-grid unit, that is it works together with the grid: it covers the consumption while the sun produces and sends the surplus into the grid, without a battery. It has electric arc protection assisted by artificial intelligence and a sealed enclosure, designed for mounting on an outside wall.

With 15,000 W of rated power it covers the daytime consumption of a medium-sized building, and on the panel side it accepts up to 22,500 Wp, that is about 1.5 times the output power. The four string connections, two per MPPT, allow a large roof to be split over several slopes or orientations, each pair being tracked separately. The unit has 21 kg and 546 x 460 x 228 mm, works between -25 and +60 °C and up to 4,000 m altitude, so in mountain areas as well. The cooling is fan-assisted, so it is worth mounting where the slight noise does not disturb, and the grilles must be kept clean.

AI-assisted AFCI, string fault detection, residual current monitoring, type II SPD on DC and class II on AC, anti-islanding, AC overcurrent and DC reverse polarity protection, PID recovery; IP66 enclosure with fan cooling, 21 kg, 546 x 460 x 228 mm, -25...+60 °C, maximum altitude 4,000 m; RS485 and Smart Dongle-WLAN-FE, 4G optional; compliant with EN/IEC 62109-1/-2, VDE-AR-N 4105 and 4110, EN 50549, CEI 0-21, CEI 0-16, G99, IEC 61727/62116.

Who it suits

Suitable for a building with high consumption during the day — guesthouse, workshop, offices — with a three-phase connection and a roof that can take 15-22 kWp of panels.

Terms explained

• Full-load MPPT range: The voltage range in which the inverter can deliver the whole power; the panel strings are dimensioned to work inside it, here 410-800 V.
• Weighted European efficiency: An average of the efficiency, calculated over the operating regimes of an ordinary year; it is closer to reality than the maximum peak value.
• String: A group of panels connected in series; four string connections allow the roof to be split over several slopes or orientations.
