What Is Full Home Back Up And Why You Might Need It. A Couple Sitting In The Dark During A Power Cut.

When the Lights Go Out: Could You Cope Without Power?

At 12:33 on April 28, 2025 Spain experienced a massive nationwide power cut. Whole towns plunged into darkness. Fridges stopped. Broadband died. Mobile phone networks were overloaded. Businesses halted. Homes sat in silence, some with no heating, no cooling and no clue how long it would last.

Now imagine for a moment:
It’s 6:30PM in November.
You’re halfway through cooking dinner.
The power cuts out.
And stays out.

No lighting. No Wi-Fi. No heating.
No way to charge your phone.
No updates. No clue what’s going on.

It’s not just inconvenient. It’s helpless.


“But I’ve Got Solar, So I’m Covered, Right?”

Not necessarily.

Most grid-tied solar PV systems automatically shut down during a power cut. Why? Safety, so your system doesn’t send electricity back to the grid while engineers are working on repairs.

That means even if the sun is shining and your battery is charged, your home might still go dark unless you have something else in place…


Introducing: Full Home Back-Up

A full home back-up system is exactly what it sounds like, a way to keep your entire home running during a power cut.

Here’s how it works:

  • Your solar panels and battery charge as normal during the day.

  • If the grid goes down, a smart backup inverter kicks in automatically.

  • Your battery powers the circuits in your home; lights, fridge, Wi-Fi, sockets all without any interruption.

  • If you’ve got enough storage, you can run your home for hours or even days.


Who Needs Full Home Back-Up?

✔️ Families who want reassurance that the heating will stay on, the oven will still cook dinner, and the kids won’t be left without a nightlight.

✔️ Homeworkers and business owners who rely on broadband, laptops, and a stable environment to keep things running.

✔️ Anyone who values energy independence and doesn’t want to rely on the luck of the grid.


Peace of Mind You Can Feel

Power cuts are no longer a third-world problem. The UK grid is under pressure, and the risk is growing,  whether from weather, ageing infrastructure, or energy demand spikes.

With a full home back-up system:

  • Your lights stay on.

  • Your food stays cold.

  • Your home stays liveable.

It’s about comfort, control, and confidence, no matter what’s happening outside.


Want to Know If It’s Right for You?

We’ll show you what’s possible based on:

  • Your energy needs

  • Your home layout

  • Your existing (or planned) solar system

There’s no guesswork, no jargon, and no obligation. Just clarity.
