Deye SUN-5K-SG04LP3-EU Three-Phase Hybrid Inverter

The Deye SUN-5K-SG04LP3-EU is a three-phase hybrid inverter designed as an advanced energy management solution, ideal for both residential and commercial photovoltaic installations. This device integrates solar power generation with battery storage capability, allowing for optimal energy usage and significantly improving overall system efficiency.

The SUN-5K-SG04LP3-EU inverter features high battery charge and discharge performance, supporting a maximum charge/discharge current of up to 190A. This enables rapid energy storage and delivery, essential for flexible response to energy demands. The system also supports energy storage from diesel generators, enhancing energy security, particularly in locations requiring reliable backup power sources. The inverter allows for parallel operation of up to 10 units in both on-grid and off-grid modes. Its flexible energy storage design supports parallel battery connection. The device supports retrofitting of existing PV systems via AC coupling. Advanced energy management is enabled with six configurable charging and discharging time periods. The inverter operates with 48V low-voltage batteries and features transformer isolation for enhanced safety and reliability. A key feature is the 100% unbalanced output, where each phase can supply up to 50% of the rated power (5000W), ensuring stability even with uneven loads.

In terms of technical data, the inverter supports lead-acid or lithium-ion batteries within a voltage range of 40-60V, with automatic adjustment to the Battery Management System (BMS). On the PV side, the SUN-5K-SG04LP3-EU has 2 MPP trackers, each supporting 1+1 strings. The maximum PV input power is 6500W, with an MPP voltage range of 200-650V. The inverter delivers high efficiency: maximum efficiency is 97.6%, European efficiency is 97%, and MPPT efficiency exceeds 99%.

The device is equipped with various protections, including DC reverse polarity protection, AC output overcurrent, overvoltage, and short-circuit protection, thermal protection, leakage current monitoring, and anti-islanding detection. It operates in a wide temperature range from -40°C to +60°C (with derating above 45°C) and humidity from 0-100%. The noise level is low (≤55 dB), and the IP65-rated housing ensures durability under various environmental conditions, including outdoor installations. Cooling is managed intelligently via air. The inverter weighs 38 kg and has compact dimensions of 422x658x254 mm (excluding connectors and brackets). It comes with a standard 5-year warranty, extendable to 10 years, and complies with numerous safety and grid regulations.

Communication and monitoring are available through options like GPRS, WIFI, Bluetooth, 4G, and LAN (optional), as well as RS485, RS232, and CAN interfaces, facilitating system integration and management.
