HUAWEI SmartGuard

Grid Goes Off, Life Goes On

Three-phase Whole Home Power Backup, We've Got You Covered.

From offering power backup for partial loads to a total power support of 63 A for the whole house, you've witnessed a great leap*. No additional switchboard is required to support the backup and non-backup loads, because the current range is offering sufficient power supply.
With up to 36 KW of backup capacity, it ensures reliable power supply during outages to meet higher power demands.

*Support 63A of the whole house when on grid and may vary according to inverter capacity when off grid.

Bypass Mode for More Secure Backup

A spare bypass switch is to give you a more secure backup experience. If the contactor is defective, manual bypass is ready to support. You can turn on the bypass mode to connect loads and power up again. No worries of failure, we've got your back from the start to the end.

Built-in EMMA, for More Intelligent Scheduling

Your home energy management assistant, EMMA, is pre-integrated in SmartGuard. Home appliances can be flexibly controlled through the Shelly sockets, supporting power usage priority sorting and schduled power usage.

Seamless Switch, Faster than a Blink

With a SmartGuard at home, whenever power outages strike, you will be safeguarded by an ultra-fast switchover from grid to solar backup power, which is faster than the blink of an eye.


Household appliances can't even feel the interruption, continuously working as if no blackouts occurred.
