Deye SUN-12K-SG05LP3-EU-SM2 – Three-phase hybrid inverter 12 kW (Low Voltage)

Deye SUN-12K-SG05LP3-EU-SM2is powerfulnew generation three-phase hybrid inverter, created forresidential and commercial solar systems with energy storage.
He combinedhigh efficiency, intelligent energy managementandflexibility at workas inon-grid, as well as inoff-grid and backup modes.

The inverter supportslow voltage 48V batteries, ensuring safe operation, high efficiency and easy compatibility with popular storage systems such asDYNESS DL5.0C Pro, Pylontech, Sofar, Deye Batteryand others.
Thanks totransformer insulationandhigh class protection IP65, the device is suitable for outdoor installation and long-term operation in harsh climatic conditions.

Main advantages

• Compatible with 48V batteries– safe low voltage technology ideal for home and small commercial systems.

• Full hybrid functionality– supports on-grid, off-grid, and backup mode.

• Max. charge/discharge current 240A– guarantees fast response and high power under load.

• Parallel operation of up to 10 inverters– enables scalable solutions for large systems.

• Intelligent energy management– optimization through 6 programmable charging/discharging time periods.

• 100% unbalanced output– each phase can deliver up to 50% of the nominal power.
