The Deye SG05LP3-EU-SM2 series is a range of three-phase hybrid inverters supporting low-voltage (48 V) batteries, designed for residential and light commercial solar systems.
The series covers power ratings from 3 kW up to 18 kW, with the specific models 5K, 6K, 8K, 10K, 12K, 15K, 16K, and 18K corresponding to model numbers SUN-3/4/5/6/8/10/12K-SG05LP3-EU-SM2 and SUN-14/15/16/18/20K-SG05LP3-EU-SM2, according to Deye’s official documentation.

These inverters intelligently manage energy by combining power from photovoltaic panels, batteries, and the grid to ensure a reliable and efficient power supply — even during grid outages. They also support AC coupling, allowing integration into existing solar systems.

Key Features

• Hybrid functionality: Configurable for on-grid, off-grid, and backup applications. Can also store energy from a diesel generator to ensure continuous power supply.

• Optimal solar energy harvesting: Two independent MPPT trackers maximize solar output under varying conditions or panel orientations.

• Low-voltage battery support: Compatible with 48 V lead-acid and lithium-ion batteries; transformer-isolated design ensures enhanced safety.

• Efficiency: PV > 97.6 % / Battery round-trip > 95 %.

• Smart energy management: Up to six programmable time periods for battery charging/discharging, allowing tariff-based optimization.

• High scalability: Parallel operation of up to 10 units for both on-grid and off-grid configurations.

• Three-phase unbalanced output: Supports 100 % unbalanced load; each phase can handle up to 50 % of rated power.

• Durable design: IP65 protection against dust and water, suitable for outdoor use; operating temperature −40 °C to +60 °C.

• Comprehensive protection: Reverse DC polarity, AC overcurrent/overvoltage, thermal, DC component, and ground-fault current monitoring.

• Remote monitoring: RS485, RS232, CAN communication; optional Wi-Fi, GPRS, or 4G dongle for Deye Cloud connectivity.
