Three Phase Hybrid Inverter |SUN-18K-SG05LP3-EU-SM2 | 18kW | For 48V Batteries | 10 year warranty

Product description:
DEYE Three Phase 18 KW Low Voltage Hybrid Inverter (model SUN-18K-SG05LP3-EU-SM2) is a powerful hybrid inverter designed for three-phase solar systems with low voltage batteries (48V). It combines energy from solar panels, batteries and mains power, providing efficient energy management. The inverter supports both on-grid and off-grid operation and can operate up to 10 devices in parallel for large-scale systems. The system offers remote monitoring and control via built-in Wi-Fi connectivity.

Compatible batteries:

• Pylontech US2000 / US3000 / UP2500

• BYD Battery-Box LVS

• Dyness B4850 / 5.12kWh

• SolaX Triple Power LV

• Key benefits:

  • 48V battery support– stable storage and quick response to load

  • 2 MPPT trackers– optimize the production of different arrays and slopes of the panels

  • EPS mode– provides power supply to critical loads in the event of a network failure

  • Intelligent monitoring and management– via mobile application and SolisCloud platform

  • Advanced Protection:anti-islanding, overvoltage, short circuit, thermal protection, AFCI (optional)

  • AC Coupling Support– ability to connect to diesel generators or existing systems

  • Compact performance and low noise level– ideal for residential and commercial installations

Application:
The SUN-18K-SG05LP3-EU-SM2 is ideal for large solar systems, providing reliable power and flexibility when working with different energy sources. This inverter is suitable for home and small commercial applications that require large-scale energy management.
