Haier Energy and enwitec rely on the Power Backup Dual EU
The collaboration between Haier Energy, one of the world’s leading providers of smart energy solutions, and enwitec, the German expert for standards-compliant connection and energy management systems, centers around one key product: the Power Backup Dual EU.
At the Core: The Power Backup Dual EU by enwitec
The Power Backup Dual EU is an intelligent grid switching box specifically developed for off-grid-capable battery and hybrid inverters with two AC outputs (“Grid” and “Backup”). It enables full backup power supply for all consumer circuits – ideal for residential projects where supply security and flexibility are paramount.
Compatibility with Haier Systems
The Power Backup Dual EU is compatible with a wide range of hybrid inverters available on the market – including models from Haier. Particularly relevant is the Haier 3HP, which is listed in the compatibility list of the Power Backup Dual EU. These inverter cover power ranges from6 to 10 kWand is perfectly suited for PV systems with storage solutions in private and small commercial applications.
Benefits for Installers: Simple, Safe, Efficient
Plug & Play: The Power Backup Dual EU is ready to connect and significantly reduces installation effort.
Standards Compliance: CE-certified and compliant with EN 61439-1/-2/-3 and EN 60255-26.
Universal Application: Suitable for all hybrid inverters with two three-phase AC connections up to 30 kW.
Integrated Current Monitoring: Protects against overload of inverter relays.
Benefits for End Customers: More Independence, More Security
In combination with Haier inverters, the Power Backup Dual EU provides a reliable emergency power supply in off-grid mode – without the need for complex consumer distribution. This means: even in the event of a grid failure, all essential household consumers remain powered. The result is a well-thought-out overall system that combines comfort, control, and supply security.
Conclusion: A Strong Alliance for the Energy Future
The partnership between Haier Energ and enwitec demonstrates how smart technology and collaborative thinking lead to real solutions – for installers, for end customers, and for a sustainable energy future. At the heart of it all is the Power Backup Dual EU – a product that sets new standards in safety, efficiency, and future-readiness.
