Deye Tri 8.8 kW Hybrid Inverter – SUN-8K-SG05LP3-EU-SM2

Deye SUN-8K-SG05LP3-EU-SM2: the 8.8 kW three-phase hybrid inverter designed for large homes and SMEs

The Deye SUN-8K-SG05LP3-EU-SM2 is a 48 V low-voltage three-phase hybrid inverter with a nominal AC power output of 8.8 kW. Thanks to its SG05LP3 series architecture, it sits at the top of Deye’s low-voltage three-phase range, offering the highest AC power available in this segment (8,000 W active / 8,800 VA) with a PV input of up to 12,000 W. It is designed for large homes with a high prosumer ratio, three-phase SMEs and agricultural projects seeking to combine 48 V storage, advanced energy management and uninterrupted power supply in all circumstances.

8.8 kW three-phase: performance and power-to-footprint ratio

With a maximum efficiency of 97.6% (Euro 97.0%) and MPPT efficiency of ≥ 99.9%, the SUN-8K-SG05LP3-EU-SM2 makes the most of every watt generated. Its 12, 000 W PV input for an 8,000 W active AC output represents a DC/AC ratio of 1.5 — ideal for optimising production during periods of low sunlight and smoothing out winter peaks. The maximum PV short-circuit current of 30 + 30 A makes it compatible with high-power panels (500–700 Wp) without current limitation.

• Nominal AC power: 8,000 W active / 8,800 VA max
• Max PV input: 12,000 W — 2 MPPT (200–650 V, max 800 V) — 20 A per MPPT
• Max PV short-circuit current: 30 A per MPPT
• Max efficiency: 97.6% — Euro: 97.0% — MPPT: ≥ 99.9%
• Output THDi < 3% — Power factor: 1
• Nominal AC current: 11.6 A per phase | max 15.9 A per phase

48V battery storage: extended compatibility, 190 A charging current

The SUN-8K-SG05LP3-EU-SM2 operates with 40–60 V low-voltage batteries, whether lithium-ion or lead-acid. Its maximum charge/discharge current of 190 A enables rapid recharging of a large capacity (up to ~9.7 kW at 51.2 V) to meet three-phase consumption peaks. BMS management is automatic via CAN, RS485 or RS232 — the inverter is compatible with Pylontech, DeLong, Leapton, Dyness, WECO and other compatible brands.

Advanced energy management: Time of Use, Peak Shaving, generator

The SUN-8K-SG05LP3-EU-SM2 offers one of the most comprehensive energy management systems in its class, with an intuitive touchscreen LCD interface:

• 6 Time of Use time slots: charge during off-peak hours, discharge during peak hours — reduce your energy bill
• Peak Shaving: limits power drawn from the grid to prevent exceeding your contracted power limit
• Self-consumption mode: solar priority, battery charging with surplus, feeding the rest back into the grid
• Zero-feed-in mode: no feed-in to the grid, ideal for prosumers without a feed-in tariff agreement
• Priority feed-in mode: maximum feed-in to the grid (resale)
• Off-grid / backup mode: autonomous power supply from battery + panels in the event of a power cut
• Diesel generator compatibility: dedicated GEN port for battery charging during low solar output
• Battery-free mode: operates as a pure grid-tied inverter without storage
• Parallel operation: up to 16 units in parallel for installations up to 140 kW

Main Screen

The LCD screen is touch-sensitive and displays general information about the inverter.

1 • The icon in the centre of the home screen indicates that the system is operating normally. If it displays "comm./F01~F64", this means that the inverter has communication errors or other faults. The error message will appear below this icon (errors F01-F64; details of the errors can be viewed in the System Alarms menu).

2 • The time is displayed at the top of the screen.

3 • System configuration icon. Press this button to access the system configuration screen, which includes basic configuration, battery configuration, grid configuration, system operating mode, generator port usage, advanced functions and Li-Ion battery information.

4 • The main screen displays information regarding solar, grid, load and battery. It also indicates the direction of energy flow using arrows. When power approaches a high level, the colour of the panels changes from green to red, allowing system information to be clearly viewed on the main screen.

- PV power and charging power always remain positive.

- A negative grid power reading indicates power being sold to the grid; a positive reading indicates power being drawn from the grid.

- A negative battery power reading indicates charging; a positive reading indicates discharging.

Remote shutdown function

Smart monitoring platform
