Deye SUN-6K-SG05LP3-EU-SM2

This three-phase hybrid inverter links into a single system the panels, the battery, the grid and the loads of a house connected on three phases. During the day it uses the solar energy directly in the house and puts the surplus into the battery, in the evening it draws from the battery, and if the grid goes down, it keeps supplying the home. It can be set so that it does not send current into the grid, but only covers its own consumption, if the connection requires it.

With 6000 W active power (6600 VA) and 9,1 A on each phase, it can support the usual loads of a three-phase house, and in the absence of the grid it delivers twice the rated power for 10 seconds, enough to start a motor or a pump. Modules totalling up to 9600 W can be connected, on two trackers with two strings each, and the maximum input voltage of 800 V allows long strings, therefore fewer cables. The 48 V battery charges and discharges with up to 135 A, that is roughly about 6,5 kW, with six programmable time intervals for choosing when it fills up and when it empties. The direct grid-to-load passthrough withstands 45 A. The device weighs 35,2 kg, measures 386 x 660 x 250 mm, has an enclosure sealed against dust and splashes, fans with automatically controlled speed and works between -40 and +60 °C; it is monitored from the phone through the Solarman Smart app, over WiFi or Bluetooth.

PV: 9600 W maximum module power, 2 MPPTs with 2 strings each, Vmax DC 800 V, MPPT window 200-650 V, start-up 160 V, maximum input current 20+20 A (Isc 30+30 A). AC: 6000 W active, 6600 VA apparent, 9,1/8,7 A rated current per phase, 3L+N+PE 230/400 V, 50/60 Hz, off-grid 2x Pn for 10 s, bypass 45 A, maximum efficiency 97,6%, European 97,0%, MPPT efficiency above 99,9%. Lithium-ion or lead-acid battery, 40-60 V (48 V nominal), 135 A charging/discharging, 6 programmable time intervals. RS485, RS232 and CAN communication for BMS, WiFi/Bluetooth for monitoring. IP65 enclosure with intelligent fan cooling, 386 x 660 x 250 mm, 35,2 kg, operating temperature -40...+60 °C. Certifications: IEC 61727, IEC 62116, EN 50549, VDE-AR-N 4105, EN 62109-1/2.

Who it suits

Suitable for a house with a three-phase connection and average consumption, with a panel array of up to about 9,6 kW and a 48 V battery, which wants self-consumption, possibly zero export to the grid, and backup power during an outage.

Terms explained

• Zero export to the grid: A setting through which the inverter produces only as much as the house consumes, without sending surplus into the grid; it is used when the connection does not allow energy to be delivered.
• AC coupling: The method by which this inverter is added on top of an existing solar installation, connecting on the alternating current side, without having to redo the cabling from the panels.
• IP65 protection rating: The enclosure is completely dust-tight and withstands water jets, so the device can also be mounted on an outside wall.

Technical specifications

Recommended applications

• Three-phase residential systems with 48 V battery storage
• Self-consumption with export limitation/zero export to the grid
• Backup and off-grid operation for homes
• AC coupling on top of existing on-grid photovoltaic systems

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-6K-SG05LP3-EU-SM2 is part of the SM2 generation of low-voltage three-phase hybrid inverters (48 V battery). It delivers 6.000 W active power and 6.600 VA maximum apparent power on a 3L+N+PE 230/400 V, 50/60 Hz output, with a rated current of 9,1/8,7 A per phase. In off-grid mode it provides a peak of 2 x the rated power for 10 seconds, and the grid-to-load switching (AC passthrough) withstands up to 45 A.

The photovoltaic side has 2 independent MPPT trackers, with 2 strings each, maximum DC voltage 800 V, MPPT working 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 9.600 W. The maximum efficiency is 97,6%, the European efficiency 97,0%, and the MPPT efficiency above 99,9%.

The battery can be lithium-ion or lead-acid, 40-60 V, with a maximum charging/discharging current of 135 A and 6 programmable time intervals for charging/discharging. IP65 enclosure with intelligent fan cooling, dimensions 386 x 660 x 250 mm, 35,2 kg, operating temperature -40...+60 degrees C. RS485, RS232 and CAN communication for BMS, plus WiFi/Bluetooth for Solarman Smart monitoring. Certifications: IEC 61727, IEC 62116, EN 50549, VDE-AR-N 4105, EN 62109-1/2.
