INDEPENDENT BACKUP POWER GUIDANCE
Find the Right Backup Power for Your Home
Independent guides, comparisons and practical tools to help you choose between generators, portable power stations, home batteries, solar and emerging EV backup.
UK Backup Power Calculator: tell us what you need to keep running and for how long, then calculate the backup power capacity your home needs.
Independent & unbiased
No brands, no installers — just clear guidance.
Compare with confidence
Real-world trade-offs, side by side.
Understand the true cost
Upfront price, fuel, charging and running costs.

EXPLORE GRIDRESOLVE
Start with the problem. Then choose the technology.
GridResolve is technology-neutral. We compare the practical strengths, limitations and costs of the different ways to keep your home powered.
Backup Power
Plan for outages and work out what you actually need to keep essential appliances and services running.
Generators
Compare inverter, dual-fuel and standby generators by output, runtime, fuel, noise and suitability.
Home Batteries
Understand usable capacity, output, backup duration, expansion, charging and long-term value.
Solar Power
Learn what solar can realistically contribute to backup power, recharging and everyday energy use.
Guides & Comparisons
Side-by-side analysis designed to help you choose between technologies, capacities and competing products.
THE GRIDRESOLVE APPROACH
Your problem comes first. The product comes second.
Manufacturers naturally recommend their own technology. GridResolve starts with the load, runtime, location and budget, then compares the realistic options — battery, generator, solar, hybrid and, as the market develops, EV backup.
What needs to stay on?
- Fridge & freezer
- Heating controls
- Broadband & home office
- Lighting & essentials
- Longer outage resilience
The Backup Power Planner will turn those requirements into a usable power target.
