Deye SUN-15K-SG05LP3-EU-SM2

The hybrid inverter is the device that unites the panels, the battery, the grid and the building's loads into a single system, converting the solar current into ordinary current and sending it where it is needed. When the grid goes down, it takes over the supply, without the appliances in the house feeling the interruption. The 15 kW model is intended for large homes and for small commercial activities, where consumption is constant and varied.

The 15,000 W simultaneously covers a large household with a heat pump, and in off-grid mode it can deliver 30,000 W for 10 seconds for starting motors. Up to 70 A per phase can pass through the inverter from the grid, so you can leave the whole building behind it, not just a few selected loads. Panels of up to 24,000 W can be fitted, with total PV access up to 30 kW, and the battery accepts 280 A at 48 V, that is roughly around 13 kW of charging, with the possibility of connecting several batteries in parallel when you want more autonomy. The IP65 enclosure allows outdoor installation, the noise stays under 60 dB, and maintenance practically means only cleaning the dust off the heatsink.

Active power 15,000 W, maximum apparent 16,500 VA, output 3L+N+PE 230/400 V, 50/60 Hz, 22.8 A nominal and 25 A maximum per phase, 100% unbalanced output, off-grid peak 30,000 W (2 x Pn, 10 s), AC pass-through 70 A. Two MPPTs with a wide range 160-650 V, start-up at 160 V, maximum DC voltage 800 V, input current 36+36 A, maximum module power 24,000 W, total PV access up to 30 kW; maximum efficiency 97.6%, European 97.0%. Lithium-ion or lead-acid battery 40-60 V, 280 A charge/discharge, multiple batteries in parallel, 6 time slots, AC coupling for retrofit and storage from a diesel generator. Overall size 456 x 750 x 268.5 mm, 51.9 kg, IP65, -40...+60 degrees C, under 60 dB, RS485/RS232/CAN and WiFi/Bluetooth communication; compliance IEC 61727, IEC 62116, EN 50549, VDE-AR-N 4105, CEI 0-21, G99, EN 62109-1/2.

Who it suits

Suitable for a large villa or a small company's premises, with an installation of up to 24 kWp, that wants backup for the whole building and storage on 48 V batteries.

Terms explained

• Off-grid: The mode in which the inverter supplies the building by itself, from the panels and the battery, without help from the public grid.
• Batteries in parallel: Several battery modules connected together, so that you increase the autonomy without changing the inverter.
• Total PV access: The total panel power that can be physically connected, greater than the one processed at any given moment, precisely so that the system delivers more on weak days.

Technical specifications

Recommended applications

• Villas and large three-phase homes with 48 V storage
• Small commercial applications and workshops
• Hybrid systems with a backup diesel generator
• AC-coupled retrofit with full building backup

Warranty

5 years standard, extendable to 10 years depending on Deye's regional policy

Technical details

Specifications confirmed from the manufacturer's datasheet

The Deye SUN-15K-SG05LP3-EU-SM2 belongs to the low-voltage three-phase hybrid series 14-20 kW, designed for large residential installations and small commercial applications with storage on 48 V batteries. The rated active power is 15,000 W, and the maximum apparent power 16,500 VA, on a 3L+N+PE 230/400 V output, 50/60 Hz, with 22.8 A rated current and 25 A maximum current per phase. It offers 100% unbalanced output, an off-grid peak of 30,000 W (2 x rated, 10 s) and grid-to-load AC pass-through of up to 70 A.

The 2 MPPT trackers work over a wide range, 160-650 V, with start-up at 160 V, maximum DC voltage 800 V and maximum input current 36+36 A. The maximum power of the connected modules is 24,000 W, and total PV access can reach 30 kW. Maximum efficiency 97.6%, European efficiency 97.0%.

The battery can be lithium-ion or lead-acid 40-60 V, with a maximum charge/discharge current of 280 A and the possibility of connecting several batteries in parallel. It supports 6 charge/discharge time slots, AC coupling for retrofit and the storage of energy from a diesel generator. IP65 enclosure, intelligent cooling, 456 x 750 x 268.5 mm, 51.9 kg, -40...+60 degrees C, noise under 60 dB. RS485/RS232/CAN, WiFi/Bluetooth communication. Certifications: IEC 61727, IEC 62116, EN 50549, VDE-AR-N 4105, CEI 0-21, G99, EN 62109-1/2.
