Deye SUN-50K-G03 — is a highly efficient 50 kW three-phase string inverter designed for commercial and industrial solar power plants. The device delivers a maximum efficiency of up to 98.7%, features 4 independent MPP trackers, and supports a wide input voltage range of 200–850 V. Thanks to its well-designed architecture, the inverter integrates easily into complex photovoltaic systems and ensures stable operation even under variable lighting conditions.
The model supports Zero Export (energy export limitation) and the VSG (Virtual Generator) function, allowing the inverter to operate as part of a microgrid. The device has an IP65 protection rating, ensuring safe outdoor operation, and a “smart” cooling system that maintains low noise levels (<50 dB). The inverter supports remote software updates and parameter changes via RS485, RS232, Wi-Fi, or LAN interfaces.

Features
The Deye SUN-50K-G03 inverter features a transformerless architecture, enabling high efficiency with low energy losses. Thanks to four MPP trackers, the inverter easily adapts to complex solar array configurations. The built-in monitoring system controls the current and voltage of each string, enabling optimized energy production.
The inverter features a full suite of protection functions—from isolation to grid failure detection (Anti-Islanding Protection). It supports software updates, remote configuration, and integration into power grid dispatch systems. Thanks to its compact housing, high IP65 protection rating, and minimal noise, the SUN-50K-G03 is ideal for outdoor installation.
Applications
- Medium- and large-scale commercial solar power plants;
- Industrial facilities, warehouses, shopping centers, agricultural enterprises;
- Grid-connected generation systems with export limitation;
- Microgrids with VSG (Virtual Generator) support;
- Facilities requiring low noise and high efficiency.
