Deye SUN-20K-SG05LP3-EU-SM2 is a high-performance 20 kW hybrid inverter developed for operation in three-phase grids. It uses 48 V battery packs and features a high charging current of up to 350 A, which makes it possible to build a stable and efficient power supply system for a home, a business or industrial facilities. Support for three-phase connection ensures versatile application.
The inverter efficiency reaches up to 97,6%, which guarantees minimal energy losses and high efficiency of the entire system. The device can work with different energy sources: solar panels, the centralised power grid and generators (petrol or diesel). Low-voltage 48 V batteries are used for backup power. Lithium iron phosphate (LiFePO₄) batteries deliver the best results.
The inverter makes it possible to feed surplus electricity into the grid under the “green tariff” programme, which opens up the possibility of additional income from generation. The intelligent monitoring system provides flexible parameter configuration and allows the solar power plant to be controlled remotely.
Key advantages of the inverter
- Two MPPT trackers, each with two strings, which allows up to 4 separate solar panel arrays to be connected. This makes it possible to place panels on different planes — on the roof or on the ground, with different orientations and connection schemes.
Input parameters: current 36A + 20A, operating voltage — 160–650 V.
- A high charging current of up to 350 A, which ensures fast battery charging and efficient system operation.
- Compatibility with diesel and petrol generators for backup power supply.
- A reliable protection system against overloads, short circuits and other emergency situations.
- A convenient monitoring system for supervising the solar power plant in real time.
- Scalability — support for parallel connection of up to 10 inverters to increase system power.
