The Deye SUN-20K-G04 20kW On-Grid Inverter is a high-performance, smart inverter engineered for demanding commercial and industrial solar applications. Whether it’s a rooftop installation on a factory, warehouse, or solar farm, this three-phase inverter delivers uncompromising efficiency, superior monitoring, and outstanding durability all packed into a sleek, compact design.
At the heart of the SUN-20K-G04 is dual Maximum Power Point Tracking (MPPT) functionality, allowing two separate solar string configurations for increased energy yield. With a wide MPPT voltage range of 160V to 1000V, the inverter ensures optimized energy harvesting across various panel orientations, shading conditions, and layouts — giving system designers true flexibility.
Boasting an industry-leading maximum efficiency of 98.6%, this inverter transforms solar power into usable AC electricity with minimal energy loss. With a high DC input voltage of 1100V and max input current of 26A per MPPT, the SUN-20K-G04 can support modern high-efficiency PV modules and long strings — reducing BOS (Balance of System) costs.
From high temperatures to heavy rain, the Deye SUN-20K-G04 doesn’t flinch. With an IP65-rated aluminum alloy enclosure, the inverter withstands the harshest outdoor environments. Internal systems are safeguarded by comprehensive protection mechanisms including:
Anti-islanding
Over/under voltage protection
Overcurrent and short circuit protection
Reverse polarity detection
Overtemperature shutdown with smart fan cooling
✔️ High efficiency and excellent thermal design
✔️ Perfect for commercial, industrial, and large-scale rooftop PV systems
✔️ Flexible and modular for scalable solar arrays
✔️ Reliable grid compliance and safety certifications
✔️ Smart monitoring + remote diagnostics = peace of mind
