Overview:
A rural homeowner in the UK faced a major challenge when planning their new property: the cost of connecting the house to the national grid was prohibitively high. With the nearest grid connection point more than one hundred metres away, the quoted installation cost ran into tens of thousands of pounds—before even considering ongoing electricity bills and standing charges.
To overcome this, the homeowner turned to Electrical & Energy Solutions Ltd for a fully off‑grid alternative that would deliver reliable, efficient, and future‑proof power.
The Challenge
- Excessive grid connection cost due to remote location
- Long‑term financial burden from rising electricity prices and standing charges
- Need for a dependable, year‑round power supply
- Desire for a sustainable, low‑maintenance solution
The client wanted a system that could operate independently, provide seamless power, and avoid the ongoing costs associated with traditional grid electricity.
Our Solution
Electrical & Energy Solutions Ltd designed and installed a complete off‑grid energy system built around the advanced Sigenergy product range. The installation included:
- Sigenergy Gateway
The gateway acts as the central control hub, intelligently managing energy flows between the inverter, batteries, generator, and household loads. It ensures the home always has stable, uninterrupted power.
- SigenStor 12kW Hybrid Inverter
This high‑performance inverter converts stored energy into usable electricity for the home. Its hybrid capabilities allow it to:
- Manage battery charging and discharging
- Supply loads for heat pump and cooking
- Optimise energy usage based on demand
- 32 kWh of SigenStor Battery Storage
A robust battery bank provides ample capacity to power the home day and night. Key benefits include:
- Reliable energy storage for off‑grid living
- High‑efficiency charging
- Ability to easily replace or add extra batteries as needed
- Sigenergy 5-level protection
- Generator Integration
A backup generator was incorporated into the system to provide additional resilience during periods of exceptionally high demand or prolonged low‑solar conditions. The Sigenergy Gateway automatically manages generator start‑up and shut‑down, ensuring efficient operation.
- Home assistant integration
Home assistant was added for local control of inverter without the need for cloud based control adding full resilience for internet blackout
The Results
The completed installation delivered a fully autonomous power system that meets the homeowner’s needs year‑round. Key outcomes include:
Significant Cost Savings
- Avoided grid connection costs, which were far higher than the off‑grid installation
- No standing charges or ongoing grid‑related fees
- Reduced long‑term energy costs thanks to efficient battery storage and intelligent energy management
Energy Independence
The homeowner now enjoys complete freedom from grid outages, price fluctuations, and supply limitations.
Smart, Automated Operation
The Sigenergy system continuously monitors and optimises energy usage, ensuring:
- Maximum battery efficiency
- Seamless generator support when required
- Reliable power 24/7
Future‑Ready Infrastructure
The modular nature of the SigenStor system means the homeowner can expand storage or integrate renewable generation (such as solar PV) at any time.
Conclusion
By choosing an off‑grid solution from Electrical & Energy Solutions Ltd, the homeowner not only avoided the substantial cost of connecting to the national grid but also secured a reliable, efficient, and cost‑effective energy system for the future.
This project demonstrates how modern energy technology—when designed and installed correctly—can outperform traditional grid connections both financially and operationally.
