Deye SUN-10K-SG05LP3-EU-SM2

This device is the heart of a solar system with storage: it converts the current from the panels into the current used in the house and automatically decides where the energy goes, to the loads, to the battery or to the grid. Being hybrid, it can do all of this simultaneously and can keep the house supplied even when the grid is interrupted. The 10 kW version is the most frequently encountered choice for three-phase homes, because it matches an ordinary family's consumption.

The continuous power of 10,000 W keeps almost all the loads of a house running at the same time; at motor start-up it delivers double the power for 10 seconds, i.e. 20,000 W. You can connect panels of up to 16,000 W, i.e. 1.6 times the inverter's power, an oversizing that brings useful energy also on overcast days. The battery is charged and discharged with up to 210 A at 48 V, i.e. roughly around 10 kW, so even a large battery pack fills up in a single sunny day. The 6 programmable time slots allow consumption to be shifted from the expensive hours into the cheap ones. The IP65 enclosure allows outdoor mounting, and the intelligent cooling starts the ventilation only when needed.

Active power 10,000 W, maximum apparent 11,000 VA, output 3L+N+PE 230/400 V, 50/60 Hz, 15.2/14.5 A rated per phase, 100% unbalanced load, peak 2 x Pn for 10 s off-grid, AC pass-through up to 45 A. Two independent MPPTs, 2 strings each, maximum DC voltage 800 V, MPPT range 200-650 V, start-up at 160 V, 20+20 A (Isc 30+30 A), maximum module power 16,000 W; maximum efficiency 97.6%, European 97.0%, MPPT above 99.9%. Lithium-ion or lead-acid battery 40-60 V, 210 A charging/discharging, AC coupling for retrofit and storage from a generator. Overall size 386 x 660 x 250 mm, 35.2 kg, -40...+60 degrees C, communication RS485, RS232, CAN and WiFi/Bluetooth; compliance with IEC 61727, IEC 62116, EN 50549, VDE-AR-N 4105, EN 62109-1/2.

Who it suits

Suitable for a three-phase house with an 8-16 kWp system and 48 V storage, which wants high self-consumption and full backup during power outages.

Terms explained

• Hybrid: An inverter that works at the same time with the panels, with the battery and with the grid, unlike a simple on-grid one, which cannot charge batteries.
• Oversizing of the PV array: You install panels with a power greater than that of the inverter; in summer a little is lost at the peak, but you gain energy in the morning, in the evening and in cloudy weather.
• Charging current (A): How fast the battery can be filled; the more amps, the earlier the battery is full on a sunny day.

Technical specifications

Recommended applications

• Three-phase residential systems of 8-16 kWp with storage
• Self-consumption and tariff arbitrage over time slots
• Full backup of the home in case of a grid outage
• Small commercial spaces and three-phase offices

Warranty

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

Technical details

Specifications confirmed from the manufacturer's datasheet

Deye SUN-10K-SG05LP3-EU-SM2 is the 10 kW three-phase hybrid inverter from the low-voltage SM2 series (48 V battery), one of the most widespread configurations for three-phase homes. The rated active power is 10,000 W, the maximum apparent power 11,000 VA, on a 3L+N+PE 230/400 V, 50/60 Hz output, with 15.2/14.5 A rated current per phase. It offers a 100% unbalanced output, a peak of 2 x the rated power for 10 s off-grid and AC pass-through of up to 45 A.

The 2 independent MPPT trackers accept 2 strings each, maximum DC voltage 800 V, MPPT range 200-650 V, start-up at 160 V and maximum input current 20+20 A (short circuit 30+30 A). The maximum power of the connected modules is 16,000 W, which allows substantial oversizing of the PV array. Maximum efficiency 97.6%, European efficiency 97.0%, MPPT efficiency above 99.9%.

Lithium-ion or lead-acid battery 40-60 V, with a maximum charging/discharging current of 210 A and 6 programmable time slots. It supports AC coupling for retrofit and the storage of energy from a generator. IP65 enclosure with intelligent cooling, 386 x 660 x 250 mm, 35.2 kg, -40...+60 degrees C. Communication RS485, RS232, CAN and WiFi/Bluetooth. Certifications: IEC 61727, IEC 62116, EN 50549, VDE-AR-N 4105, EN 62109-1/2.
