FAQs about 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 simplicity and efficiency. All components are perfectly matched by the same manufacturer and integrated in a single housing. This results in faster and easier installation, reduced space requirements and a more aesthetically pleasing appearance compared to separate individual components.

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

This powerful system is ideal for large single-family homes with high electricity consumption, especially when using heat pumps, air conditioning systems or electric cars. It is also ideal for small businesses, workshops or farms that are seeking a high degree of energy autonomy.

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

Yes, thanks to the powerful 12 kW inverter and 3-phase emergency power supply, this system can continue to supply the majority, if not all, of a typical household's consumers in the event of a grid outage, as long as the battery has sufficient charge.

Is the system expandable?

Yes, the battery system is modular. The storage capacity can generally be adjusted to future needs by adding additional compatible 5 kWh battery modules. Please refer to the manufacturer's data sheet for the maximum possible capacity.
