Huawei Backup Box for Solar Systems
Ensure uninterrupted power and peace of mind with the Huawei Backup Box – your smart solution for reliable energy during grid outages.
Overview
The Huawei Backup Box is designed to seamlessly integrate with residential solar systems, providing automatic backup power whenever the grid goes down. Intelligently switching your system from grid-tied to off-grid mode ensures that your essential appliances and loads remain powered using stored energy from your battery system. Once grid power is restored, the Backup Box automatically returns your system to standard operation.
How It Works
- Automatic Detection & Switching:
Instantly senses grid outages and switches your inverter to off-grid mode in under 3 seconds, ensuring critical loads like lighting and appliances remain powered1. - Reliable Backup Power:
Draws energy from your connected battery to supply backup power, keeping your home running smoothly during interruptions1. - Seamless Grid Restoration:
When grid power returns, the system automatically reverts to grid-tied operation, and manual intervention is required. - Smart Energy Management:
Works with self-consumption and Time of Use (TOU) modes to maximise solar energy utilisation and optimise your home’s energy consumption.
