UPS Runtime Estimator • ScopedLabs

Part of a Design Flow

This tool continues the Power design flow

Use this step to check whether the projected design load can actually be supported by the proposed UPS and its usable battery energy.

This is where the future design load gets converted into real outage duration so the final battery-bank step is based on realistic runtime expectations rather than nameplate optimism.

What this models

Projected load compared against usable UPS watt capacity
Usable battery energy after inverter efficiency and battery derate
Estimated outage duration before moving into final battery-bank sizing

Inputs

Estimated load (Watts)

UPS rating (VA)

Power factor (0.50–1.00)

Battery capacity (Wh)

If you only know Ah and V: Wh = V × Ah.

Inverter efficiency (%)

Battery health / derate (%)

Old batteries and cold rooms reduce usable energy.

Results

Enter values and calculate.

Planning-grade UPS runtime math. This is a quick sizing pass, not a vendor discharge-curve simulator. Use projected load values from the prior step so you size for where the system is going, not only where it is today.
