Deye SUN-15K-SG01HP3-EU-AM2

The inverter brings together in a single device the panels, the battery and the grid, converts the solar current into ordinary current and decides automatically whether the energy goes into the house, into the battery or back into the grid. The high-voltage battery is built from stacked modules and works with small currents, so the cables are thinner, the device heats up less and less energy is lost. When the grid fails, the inverter takes over the supply of the building without anyone's intervention.

The 15.000 W support in parallel the loads of a large building, and in the absence of the grid it delivers for 10 seconds 1,5 times the power, that is 22.500 W, for starting motors. Up to 80 A per phase can pass through the inverter from the grid, which allows a significant part of the installation to be supplied through it. Panels of up to 24.000 W can be connected, that is over 1,5 times the power of the inverter, an oversizing that brings useful energy on cloudy days and at the beginning and end of the day. The battery is charged and discharged with 50 A, but at a few hundred volts, so the energy flow remains consistent. With 30,5 kg and an IP65 enclosure, it is wall-mounted, including outdoors, and maintenance is limited to periodic cleaning of the cooling surfaces.

Active power 15.000 W, maximum apparent 16.500 VA, output 3L+N+PE 230/400 V, 50/60 Hz, 22,8/21,8 A rated and 25/24 A maximum per phase, off-grid peak 1,5 x Pn for 10 s, AC pass-through 80 A. DC side: maximum voltage 1000 V, 2 MPPT with 2+1 strings, range 150-850 V, rated DC voltage 700 V, start-up at 180 V, input current 26+26 A, maximum module power 24.000 W; maximum efficiency 97,6%, European 97,0%. Lithium-ion battery 160-700 V, maximum charge/discharge current 50 A. IP65 enclosure with natural and intelligent cooling, 408 x 638 x 237 mm, 30,5 kg, operating temperature -40...+60 degrees C, communication RS485/RS232/CAN and WiFi; compliance IEC 61727, IEC 62116, EN 50549, VDE-AR-N 4105, EN 62109-1/2.

Who it suits

Suitable for a large residential building or a commercial space with 18-24 kWp of panels and a high-voltage battery, where efficiency and low weight at installation matter.

Terms explained

• HV architecture: The system works at high voltage and low current; the practical effect is less heat in the cables and less energy lost.
• MPPT range 150-850 V: The voltage interval in which the inverter can extract energy from the panels; a wide one means the system starts early in the morning and works until evening.
• European efficiency: A weighted average of the efficiency over a real year, not only at maximum power; it is the figure closer to everyday life.

Technical details

Specifications confirmed from the manufacturer's datasheet

Deye SUN-15K-SG01HP3-EU-AM2 is the 15 kW version of the three-phase high-voltage hybrid series, designed for storage systems with lithium-ion batteries of 160-700 V. The HV architecture allows small currents on the battery side, thinner cables, reduced losses and better thermal dissipation. The rated active power is 15.000 W, the maximum apparent power 16.500 VA, on a 3L+N+PE 230/400 V output, 50/60 Hz, with 22,8/21,8 A rated current and 25/24 A maximum current per phase. In off-grid mode it offers a peak of 1,5 x the rated power for 10 s, and the AC pass-through reaches 80 A.

The PV input supports a maximum DC voltage of 1000 V, with 2 MPPT trackers (2+1 strings), working range 150-850 V, rated DC voltage 700 V, start-up at 180 V and maximum input current 26+26 A. The maximum power of the connected modules is 24.000 W, allowing a consistent oversizing of the photovoltaic field. Maximum efficiency 97,6%, European efficiency 97,0%.

The maximum battery charge/discharge current is 50 A. IP65 enclosure with natural and intelligent cooling, dimensions 408 x 638 x 237 mm, weight 30,5 kg, operating temperature -40...+60 degrees C. Communication RS485/RS232/CAN and WiFi. Certifications: IEC 61727, IEC 62116, EN 50549, VDE-AR-N 4105, EN 62109-1/2.
