3-Phase Backup System Designed & Installed by AES – Abel Environmental Services Ltd
At AES – Abel Environmental Services Ltd, we recently completed the installation of a Tesla Powerwall 3 with Expansion Pack at a residential property in Hampshire.
This advanced home battery storage project was designed not only to maximise solar energy usage, but also to deliver true backup power resilience — particularly important as the property operates on a 3-phase electricity supply.
Project Overview
📍 Location: Hampshire
⚡ Supply Type: 3-Phase Electrical Supply
🔋 System Installed: Tesla Powerwall 3
➕ Additional Capacity: Tesla Expansion Pack
🛠 Special Requirement: Dedicated Backup Circuit & Essentials Board
This installation required careful electrical design to ensure that essential household circuits would continue operating seamlessly during a grid power cut.
Tesla Powerwall 3 with Expansion Pack – Why This System?
The Tesla Powerwall 3 is one of the most advanced home battery storage systems available in the UK. Paired with an Expansion Pack, it provides increased storage capacity, making it ideal for larger homes and properties with higher energy demand.
Key Benefits:
- High-capacity energy storage
- Integrated inverter technology
- Whole-home energy monitoring
- Intelligent load management
- Seamless backup functionality
- Future-ready solar compatibility
For this Hampshire property, the expansion pack ensured sufficient battery capacity to support essential loads during extended grid outages.
3-Phase Supply & Backup Circuit Design
Installing battery storage in a 3-phase property presents unique challenges compared to standard single-phase homes.
To ensure reliable operation during a power cut, AES designed and installed a dedicated backup (essentials) circuit.
What This Involved:
- Identifying all essential household circuits
- Rewiring those circuits into a new essentials distribution board
- Separating non-essential high-load appliances
- Configuring the Tesla system for controlled backup supply
- Ensuring full compliance with UK electrical regulations
This approach guarantees that during a power outage, the Powerwall 3 automatically supplies power only to the critical circuits — preventing overload and ensuring stable, uninterrupted performance.
What Circuits Were Protected?
Typical essential circuits in projects like this include:
- Lighting circuits
- Refrigeration
- Broadband & communications
- Heating controls
- Security systems
- Key socket circuits
By consolidating these onto a dedicated backup board, the homeowner now benefits from trouble-free operation during grid failure without risking system overload.
Seamless Backup Operation
One of the standout features of the Tesla Powerwall 3 system is its near-instant switchover capability.
In the event of a power cut:
- The system detects grid failure
- Automatically isolates from the grid
- Supplies stored energy to the essentials board
- Maintains stable voltage across protected circuits
For the homeowner, this means minimal disruption — lights stay on, Wi-Fi continues running, and critical systems remain operational.
Benefits of Tesla Powerwall Installation in Hampshire
With rising energy costs and increasing grid instability, more homeowners across Hampshire are investing in battery storage solutions.
This project delivers:
- Increased energy independence
- Protection against power outages
- Greater control over electricity usage
- Reduced reliance on peak-rate grid energy
- Future compatibility with solar PV systems
For 3-phase properties in particular, professional design and installation are essential to ensure safe and reliable performance.
