Huawei SmartGuard-63A-T0

Backup

The Huawei SmartGuard-63A-T0 offers a complete three-phase backup solution for residential buildings with a service connection of up to 63 amps; it can also be integrated with the SmartAssistant using current transformers for service connections exceeding 63 amps. In the event of a power outage, it switches to emergency power in less than 20 milliseconds using MAP0 inverters and keeps all essential loads running without any noticeable interruption.

 

Thanks to the integrated SmartAssistant SA4H-A02, heat pumps, wallboxes, and smart devices can be intelligently controlled, and self-consumption can be specifically optimized. Installers benefit from a compact device that combines backup power, grid disconnection, and energy management in a single unit.
