Highlights at a glance

Integrated complete system consisting of inverter and lithium iron phosphate battery
15 kWh storage capacity, modularly expandable up to 30 kWh
4 ms emergency power switchover time for uninterruptible supply
Simple installation without additional wiring between the modules
Convenient control via app, touch display or PC

Technical performance

The system achieves a nominal AC power of 12,000 watts and a maximum PV input power of 24,000 watts. Two MPPT trackers ensure optimum energy yields for different roof orientations. The MPPT voltage range is between 200 and 650 volts, the maximum PV input current is 48 amps per tracker. The maximum efficiency is 97.6 per cent, the charging and discharging efficiency is 95.5 per cent.

Energy storage and expansion

The system uses three stackable LiFePO4 battery modules with 5.12 kWh each. These are safe, durable and maintenance-free. The battery cells offer over 6000 charging cycles at 90 per cent depth of discharge (DoD) and an end-of-life capacity of 70 per cent. If required, the system can be expanded to up to 30 kWh (six modules). The expansion is carried out without tools via plug connections.

Safety and reliability

The emergency power function with a switching time of just 4 milliseconds ensures that critical loads in the household continue to run without interruption even in the event of a power failure. The IP65 protection class allows installation indoors and outdoors. The system is certified in accordance with IEC62619, VDE2510-50, CEI 0-21, EN50549-1, UN38.3 and other international standards. It is fully prepared for grid-connected, off-grid and hybrid operating modes.

FAQs for the 15 kWh Deye AI-W5.1-12P3-EU-B ALL-IN-ONE Hybrid storage system

How big is the battery and can it be expanded?

The system comes with 15 kWh of usable LiFePO₄ capacity, typically realised by three 5.12 kWh modules. It can be expanded modularly - up to 6 modules for max. 30 kWh and several units can be connected in parallel, so that a total of up to 184 kWh is possible.

What safety functions and how long-lasting is the battery?

The battery uses robust LiFePO₄ cells with an in-built BMS for protection against overvoltage, undervoltage, overcurrent, temperature, etc. It can withstand at least 6,000 cycles at 70% DoD and comes with a 10-year warranty.

Can the system also be installed outdoors?

Yes, the housing is IP65-certified, suitable for indoor and protected outdoor areas. It is designed as a stackable floor design - no wall mounting is required.

What smart functions does the system offer?

Equipped with intelligent energy management, it supports:

Peak shaving (peak load reduction)
Smart Load Control (load prioritisation)
AC coupling for PV systems
Operation via touch display, app or PC - firmware updates can also be carried out remotely.

Is parallel operation with other units possible?

Yes, up to 6 modules per unit are possible in parallel, and several AI-W5.1-12P3-EU-B systems can be networked together. This allows the capacity to be flexibly expanded - up to 184 kWh in a system network.
