Backup Power
Practical guides to backup power systems, outage planning and emergency resilience.
Power Cut Preparation for UK Homes That Works
Power cut preparation starts with essential loads, realistic runtime and safe backup choices. Plan heating, food, lighting and connectivity for UK outages.
Can You Combine Solar Panels, a Home Battery and a Generator for Backup Power?
Solar panels, a home battery and a generator can complement one another during a power cut, but only with compatible equipment and safe system controls. Learn which arrangement suits short and long outages, and what to check before combining technologies.
Essential Appliances During Power Cuts at Home
Plan essential appliances during power cuts by load, likely runtime and safety. Decide what stays on before choosing a generator, battery or hybrid system.
How to Calculate Home Backup Power Needs
Learn how to calculate home backup power for a UK property, from essential appliance loads and surge demand to battery capacity and realistic runtime.
How to Measure a Refrigerator’s Power Use Before Choosing Backup Power
A refrigerator’s running wattage does not show how much energy it uses over a full day. Learn how to measure compressor cycling, daily watt-hours and starting demand before choosing backup power.
How Long Will a Portable Power Station Run a Fridge and Freezer?
A fridge-freezer’s running watts cannot predict portable power station runtime on their own. Learn how compressor cycling, starting surge, inverter losses, battery reserves and measured energy use affect the calculation.
What Size Portable Power Station Do You Need for a Power Cut?
Work out the portable power station size you need by separating watt-hours from output watts, allowing for surge demand, conversion losses, reserve capacity and real appliance duty cycles.
Watts vs Watt-Hours: How to Calculate the Backup Power You Really Need
Watts determine whether backup equipment can run your appliances, while watt-hours determine how long it can do so. Learn how to total running loads, allow for motor surge, account for inverter losses and calculate a realistic backup-power requirement.
