Highlights at a glance

• All-in-one solution with integrated inverter and battery storage for space-saving installation
• 12 kWh usable storage capacity for high self-consumption and security of supply
• Maximum PV input power of 15,600 watts for large solar installations
• Two MPPT trackers for optimal energy yields with different module orientations
• Support for grid-coupled and off-grid operation for flexible application possibilities

Efficient energy conversion for modern requirements

The Deye GB-S12K-EU storage system achieves a maximum efficiency of 97.6 percent and an MPPT efficiency of 99.9 percent. With a maximum PV input power of 15,600 watts and a DC input voltage of up to 1,000 volts, it is ideal for large solar installations. The wide MPPT voltage range from 150 to 850 volts ensures high energy yield and efficient system performance even under fluctuating irradiation conditions.

Flexibility and scalability

The system offers high flexibility through the possibility of operating up to ten devices in parallel. AC coupling enables simple integration into existing photovoltaic installations, allowing existing systems to be easily modernised. Thanks to the support of lithium-ion batteries with a voltage range from 160 to 700 volts, the system can be optimally adapted to different project requirements.

Reliability and protection

The Deye GB-S12K-EU system has comprehensive protective functions such as overcurrent, overvoltage and short-circuit protection, thermal monitoring as well as insulation monitoring of the DC connections. With IP65 protection class, it is optimally protected against dust and water and is suitable for use under demanding environmental conditions. It operates reliably in a wide temperature range from minus 40 to plus 60 degrees Celsius, with power reduction from 45 degrees Celsius to secure system life.
