Inverter DEYE SUN-20K-G04, 20 kW

This is a new-generation three-phase inverter designed to guarantee maximum efficiency, reliability, and durability. The device can be used in commercial and industrial facilities where a stable and high-performance power generation solution is essential.

The inverter features an extremely high efficiency of 97.8%, meaning the device very effectively converts the received energy into electricity with minimal losses. The unit operates extremely quietly (<45 dB) and is designed to work in various weather conditions: from -25°C to +60°C – reliable operation is guaranteed all year round. The inverter housing is robust and features an IP65 protection class, making it suitable for both indoor and outdoor installation. The device has a compact design, and natural convection cooling guarantees economical operation without additional maintenance.

This Deye device features an integrated advanced monitoring system that allows real-time tracking of energy production and overall system status. The inverter can be managed via smartphone or computer over Wi-Fi, and the integrated RS485 interface allows the device to be connected to external control or monitoring systems.

This Deye Sun inverter also features an outstanding safety system. It includes integrated DC reverse polarity protection, which prevents incorrect connection of solar module cables by automatically blocking startup – protecting the inverter from damage. There is also AC output overcurrent and overvoltage protection, which responds to grid overloads and voltage spikes – protecting both the device itself and the entire electrical system. AC short-circuit protection detects abnormal current and stops the device's operation, while thermal protection can automatically reduce the load when a critical temperature is reached.

The device is also equipped with DC insulation and ground fault monitoring, which checks the system's insulation level and immediately shuts down the inverter if damage is detected. Leakage current detection guarantees additional protection against electrical leakage.
