Description
Deye SUN-20K-SG05LP3-EU-SM2 20kW Three-Phase Hybrid Inverter
The Deye SUN-20K-SG05LP3-EU-SM2 is a high-capacity three-phase hybrid inverter engineered for large commercial, industrial, agricultural, and energy-intensive residential applications. As one of the most powerful models in Deye's low-voltage hybrid inverter range, it delivers exceptional performance, advanced energy management, and industry-leading battery integration capabilities, making it the ideal solution for customers seeking maximum energy independence and long-term operational savings. Supported by a robust 48V battery architecture, the inverter seamlessly integrates solar generation, battery storage, utility power, and generator backup into a single intelligent energy ecosystem.
With support for up to 40kW of PV access capacity, the SUN-20K enables businesses and large properties to harvest significantly more solar energy, reducing dependence on increasingly expensive grid electricity. Its dual MPPT design allows solar arrays to be split across multiple roof orientations while continuously optimizing performance from each string. The inverter delivers MPPT efficiencies greater than 99%, ensuring maximum energy production throughout the day, even in challenging installation environments.
At the core of the system is an industry-leading 350A battery charging and discharging capability, allowing rapid energy storage during peak solar production and powerful battery discharge during periods of high demand. The inverter supports both lithium-ion and lead-acid battery technologies and includes dual battery inputs, enabling the creation of large-scale energy storage systems capable of supporting substantial loads and extended backup durations. Intelligent communication with compatible battery management systems ensures safe, efficient, and reliable operation.
Designed for mission-critical applications, the SUN-20K provides seamless backup functionality during grid outages. Its unique ability to deliver 100% unbalanced output across all three phases offers exceptional flexibility for commercial and industrial environments where loads are often unevenly distributed. The inverter can also store energy from diesel generators, making it an ideal solution for remote facilities, manufacturing plants, farms, lodges, and businesses operating in areas with unreliable grid infrastructure.
Scalability is a major advantage of the SUN-20K platform. Up to 10 inverters can operate in parallel for both on-grid and off-grid applications, while multiple battery banks can be connected in parallel to accommodate future growth. Six programmable charging and discharging periods provide advanced energy management capabilities, allowing users to optimize battery usage around tariff structures, peak demand periods, and operational requirements.
Built for harsh operating conditions, the inverter features an IP65-rated enclosure, intelligent air-cooling technology, comprehensive protection systems, and advanced monitoring capabilities via WiFi, RS485, and CAN communication interfaces. With a maximum efficiency of 97.6%, the SUN-20K delivers outstanding performance, reliability, and flexibility for the most demanding energy storage projects.
