Find My Backup Power System

Choose what matters during an outage. We’ll handle the electrical calculations and show the best verified product fit for your planning inputs.

We compare battery energy, the devices that may run together, motor or compressor starting needs, and the kind of outlet or home connection required. Only exact verified configurations can appear.

2. How long do you need backup?

Choose a common duration or enter your own. We keep the exact duration in hours.

1. What do you want to keep running?

These presets are starting estimates. Your actual device may use more or less power. Use the appliance label, EnergyGuide label, manual, or a plug-in watt meter when accuracy matters.

Could these devices run at the same time?

Battery capacity is based on how long each device runs. Peak running watts are based on what may be on at the same time.

Peak load means what could be running at the same time. Leave an item checked if it may be plugged in while your other selected items are running. Uncheck it only if you plan to rotate or unplug it before using other heavy loads.

Rows default to checked for a safer first estimate, but you can edit each row.

Refrigerator helper

Use one energy basis. Refrigerator energy is not estimated as running watts times 24 hours. Startup surge is tracked separately.

Refrigerators and freezers cycle on and off. Their startup surge can happen while other items are already running. Only uncheck this if you know this appliance will not be running while the other selected loads are on.

CPAP helper

This is a planning estimate, not a medical guarantee. Verify medically important power needs from the device label, manufacturer, or healthcare provider.

CPAP power use varies by machine, pressure, humidifier, heated tubing, and power method. Confirm your machine’s requirements before relying on any backup power plan.

Review your selected appliances

Every added item appears here. Review the starting values and use model-specific surge data for motors, compressors, pumps, and microwaves.

3. Do any selected appliances need 240 V power?

Most everyday plugs in a U.S. home are 120 V. Large appliances may use a different 240 V outlet. Check the appliance label or manual if you’re unsure; we won’t substitute a 120 V product for a 240 V load.

4. Would you like solar recharging?

You don’t need to know panel watts, voltage, current, connectors, or wiring. The calculator checks those details against the verified catalog.

5. What matters most to you?

Optional. Choose any priorities that matter.
