This complete solution not only simplifies planning and installation, but also operation. Everything is controlled and monitored via a central interface, giving you maximum convenience and control over your energy supply.

Powerful three-phase performance for demanding households

With an impressive inverter output of 12 kW, this system is equipped to meet even the most demanding requirements. It can easily power energy-intensive appliances such as heat pumps, instantaneous water heaters or charging points for electric vehicles. The three-phase design ensures a balanced grid load and enables the entire house to be powered even during emergency power operation, meaning you’ll face hardly any disruption to your daily routine in the event of a power cut.

Smart and AI-powered energy management

The integrated, intelligent battery management system (BMS) not only ensures the safety and longevity of the LiFePO4 battery modules, but also controls the energy flows throughout the entire system. It can analyse weather data and your typical consumption patterns to optimise the charging and discharging process. This ensures that as much of the self-generated solar power as possible is either used by you or stored at the most cost-effective time.

FAQs on the Deye AI-W5.1 All-in-One System

What is the main advantage of an all-in-one system?

The main advantage lies in its simplicity and efficiency. All components are perfectly matched by the same manufacturer and integrated into a single housing. This results in quicker and easier installation, a smaller footprint and a more aesthetically pleasing appearance compared to separate individual components.

Who is this 12 kW / 20 kWh system suitable for?

This high-performance system is ideal for large detached houses with high electricity consumption, particularly where heat pumps, air conditioning systems or electric cars are used. It is also excellent for small commercial premises, workshops or farms seeking a high degree of energy self-sufficiency.

Can the system power my entire house in the event of a power cut?

Yes, thanks to the powerful 12 kW inverter and the three-phase emergency power supply, this system can continue to supply the majority, if not all, of the electrical loads in a typical household in the event of a mains power cut, provided the battery has sufficient charge.

Is the system expandable?

Yes, the battery system is modular. The storage capacity can usually be adapted to future requirements by adding further, compatible 5 kWh battery modules. Please note the maximum possible capacity as specified in the manufacturer’s data sheet.
