SUN-14/15/16/18/20K-SG05LP3-EU-SM2 | Three Phase LV

Three Phase Hybrid Inverter | 14-20kW | 2 MPPT | LV Battery Supported

The Deye SUN-14/15/16/18/20K-SG05LP3-EU-SM2 series, designed for three-phase systems, delivers power capacities from 14kW to 20kW. It supports 48V low-voltage batteries and features dual Maximum Power Point Tracking (MPPT) technology, offering both reliability and efficiency for diverse energy needs.

Key Features:

  • High Efficiency:
    With a maximum efficiency of 97.6% and a European efficiency of 97%, this series ensures excellent energy conversion. Moreover, its dual MPPT design optimizes solar energy harvesting, maximizing performance.
  • Intelligent Monitoring:
    These inverters provide a user-friendly smart monitoring platform. As a result, you can remotely shut down the system, adjust parameters, or update firmware. This simplifies maintenance and improves operational ease.
  • Flexible Output:
    In addition, the system supports 100% unbalanced output for each phase. Each phase can deliver up to 50% of the rated power, making it ideal for scenarios with varying load requirements.
  • Scalable Parallel Expansion:
    Another key advantage is the ability to connect up to 10 units in parallel. This works for both grid-tied and off-grid operations. Furthermore, the system allows multiple batteries to be connected, enhancing flexibility.
  • Robust Charging and Discharging Capabilities:
    The Deye Low Voltage Hybrid Inverter offers a maximum charging and discharging current of 350A. Consequently, it efficiently manages energy storage, even from diesel generators, to meet demanding applications.
  • Safe and Reliable Design:
    Lastly, safety is ensured through a 48V low-voltage battery system with transformer isolation. Additionally, six programmable time periods for battery charging and discharging enhance system stability.

 

  • 100% unbalanced output, max. output up to 50% rated power for each phase
  • AC couple to retrofit existing solar system
