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

Intelligent Allocation
 
                    
                        As the state of charge reduces, it will automatically switch off the less demanding loads and
                        feed power
                        to the preferential appliances you've set.
                        
                        The intelligent allocation fulfills your most critical requirements and guarantees more enduring
                        power
                        supply.
                    
Highly Integrated for Easy Installation
Say no to tedious assembling. SmartGuard is a highly integrated box with communication, measurement, and management functions. You can simply fix it on the wall with minimal circuit modification.

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 scheduled 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.
