Efficiency and output

The system offers a maximum PV input power of 20,000 watts and a rated output of 10,000 watts at the AC output. It operates with an MPPT efficiency of 95.5 per cent and achieves an overall system efficiency of 97.6 per cent. Two independent MPPT trackers enable optimal utilisation of the solar modules in the event of varying orientations or shading. The MPPT voltage range is between 200 and 650 volts.

Energy storage and expansion

The integrated LiFePO4 battery has a capacity of 10.24 kWh, consisting of two stackable modules, each with a capacity of 5.12 kWh. The system can be expanded to up to six modules (max. 30 kWh). For larger applications, up to 36 modules with a total capacity of up to 184 kWh can even be installed. The long-life cell chemistry enables over 6,000 charge cycles at a 90 per cent depth of discharge and an end-of-life capacity of 70 per cent.

Comfort and safety

Thanks to the rapid switchover to emergency power supply in just 4 milliseconds, the system ensures an uninterrupted power supply. It is suitable for both grid-connected and off-grid applications. The IP65 protection rating allows for use both indoors and outdoors. The system is fully certified to IEC 62619, CE, VDE 2510-50, EN 50549-1, CEI 0-21 and other European standards. Communication takes place via CAN 2.0 with the integrated battery management system.

FAQs on the 10 kWh Deye AI-W5.1-12P3-EU-B ALL-IN-ONE Hybrid Storage System

What is the battery’s capacity, and can it be expanded?

The system comes as standard with a 10 kWh LiFePO4 battery storage unit (5.12 kWh per module), which can be expanded in a modular fashion by up to 6 modules (30 kWh in total). Furthermore, by connecting additional units in parallel, the system can be scaled up to 184 kWh.

What are the battery’s safety specifications and cycle life?

The battery is based on safe LiFePO4 technology and offers a service life of over 6,000 cycles at 70% DoD (Depth of Discharge). A service life of 10 years.

Can the system serve as an emergency power supply in the event of a power cut?

Yes. The system offers an emergency power function with automatic switchover within 4 milliseconds. This ensures that the power supply is maintained immediately in the event of a mains failure (provided the installation is designed for this).

How is the system controlled and monitored?

Control is conveniently carried out via an app, a web portal or the integrated LCD touchscreen. Parameters such as state of charge, energy flows and consumption can be viewed and controlled in real time.

What smart functions does the system support?

It offers a wide range of smart features, such as:

• Peak shaving (peak load management)
   
• Smart Load Control (intelligent load prioritisation)
