# Huawei Smart Guard 63A-TO-AUTO

> Huawei SmartGuard 63A system controller for compatible Huawei residential energy storage and backup power systems. This smart controller supports 380V/400V/415V three-phase voltage and 50/60 Hz frequency. It works best with inverter-type generators, ensuring stable frequency and voltage.

## Product identity
- **Brand:** Huawei
- **SKU:** SmartGuard-63A-S0
- **MPN:** SmartGuard-63A-S0

## Description
**Huawei SmartGuard-63A-TO-AUTO** – is an advanced three-phase energy management module designed to ensure 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 energy 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, allowing stable power supply even under heavy 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 to reduce costs and ensure energy efficiency
- allows managing energy consumption and automating power supply processes
- Due to **IP55** protection against dust and water, the device is suitable for both indoor and outdoor installation
- Batteries or a generator can be connected to the system
- Thanks to the manual **BYPASS** switch, the system can be kept running even in case of faults
