Huawei Smart Guard 63A-TO-AUTO three-phase energy management module

Huawei SmartGuard-63A-TO-AUTO is an advanced three-phase energy management module designed to ensure an uninterrupted power supply. It detects grid failures and instantly switches the power supply to a backup source – batteries or a generator. It also protects sensitive appliances from power outages and allows managing power distribution between backup and non-backup loads. It can be integrated with Huawei FusionSolar APP, EMMA, and Shelly systems. It works best with inverter-type generators, ensuring stable frequency and voltage. The generator must not be connected directly to the SmartGuard, but via a backup load panel. Shelly smart switches can be used for automatic generator start/stop. The EMMA system can optimize energy distribution, starting the generator only when necessary.

Key features:

• supports up to 63 A current, enabling stable power supply even under high loads

• in the event of a power outage, switching to backup power occurs within ≤20 ms, protecting sensitive appliances from shutting down

• optimizes power supply using EMMA, helping reduce costs and ensuring energy efficiency

• allows energy consumption management and automation of power supply processes

• thanks to IP55 dust and water protection, the device is suitable for both indoor and outdoor installation

• batteries or a generator can be connected to the system

• manual BYPASS switch keeps the system operational even in the event of a malfunction
