UPS runtime calculator
Choose the equipment, then estimate backup time.
What are you powering?
Desktop type
Includes the computer and one typical monitor. Gaming and workstation loads allow for higher-power graphics.
Laptop type
Based on a typical charger rating. Use the wattage printed on your charger when you have it.

Equipment figures are practical averages, not product specifications. Check the power label on the computer, charger, cameras, NVR, PoE switch, monitor and storage. Runtime assumes 80% usable battery capacity and 85% inverter efficiency.
Solar & battery calculator
Estimate panels from your electricity bill and backup from the appliances you need in a power cut.
Add your electricity bill
Use a recent bill, then confirm the meter readings or units used.
Photo added. It stays on your device — confirm the numbers below.
Use the consumption units — not the barcode, CNP, computer code or meter number.
Choose outage essentials
Select what must keep running when the power is out.
Calculation assumptions
- Monthly units ÷ billing days gives your average daily energy use.
- Panel count includes a 20% allowance for typical system losses.
- Battery size uses the selected outage load, backup hours, 90% usable capacity and 90% inverter efficiency.
- Inverter size includes 25% headroom, but motor and air-conditioner start-up surge still needs checking.

This is a planning estimate. Our solar team will confirm roof space, shading, wiring, surge loads, panel direction and equipment compatibility before you buy or install.
Storage calculator
Work out how much hard drive space you need, then pick a drive that's in stock.
