Off-Grid & Power-Cut Backup
Battery backup that keeps essential circuits running during a power cut, fitted by MCS-certified installers UK-wide.
Solar panels generate the energy; a properly configured battery system decides what happens when the grid disappears. Our off-grid and power-cut backup service designs your storage around the circuits you cannot afford to lose — fridge, lighting, Wi-Fi, medical equipment — so they switch over automatically the moment the mains fails. Working through our network of MCS-certified installers, we specify the right inverter topology, transfer switching, and load management to keep essentials running without manual intervention. It is the practical payoff of home battery storage: not just lower bills, but genuine resilience when the network goes dark.
Why it matters
A power cut backup battery turns an outage from a disruption into a non-event for the circuits that matter most. You keep food safe, stay connected, and maintain critical health equipment without starting a generator or hunting for torches. The system isolates from the grid instantly, protecting both your home and utility workers, then reconnects seamlessly when supply returns. It extends the value of every solar kWh you generate, letting you use stored energy precisely when it delivers the highest personal impact. Independence means choosing which loads survive a blackout — and knowing they will, every time.

Frequently asked questions
Will my battery power the whole house during a power cut? +
Only the essential circuits you select — whole-home backup requires a much larger system and is rarely cost-effective.
How fast does the switch to battery power happen? +
The transfer is typically under 20 milliseconds, fast enough that lights do not flicker and sensitive electronics stay online.
Can I add backup capability to my existing solar and battery system? +
Yes, if your inverter supports islanding and a backup consumer unit can be fitted; our installers will assess compatibility.
