Backup power calculators
Estimate UPS runtime and battery capacity from entered load, usable energy, efficiency and reserve assumptions.
Backup power calculators project basis
Estimate UPS runtime and battery capacity from entered load, usable energy, efficiency and reserve assumptions. These calculators support Australian design, estimating, installation and verification preparation. Keep the circuit, equipment, route, supply arrangement and source data with the result before it is used in a project record.
More
Confirm the nominal 230/400 V a.c. or project-specific voltage basis, 50 Hz context where applicable, phase arrangement, metric units, manufacturer information, DNSP or authority conditions and current project documents before applying a result.
Check entered values, supply arrangement, cable or equipment data, product limits, DNSP or authority conditions and review limits before using the result.
Records covered
- UPS runtimeEstimate UPS runtime from entered battery energy, load, efficiency and usable fraction. Inputs: Battery energy, load, efficiency and usable fraction. Output: UPS runtime worksheet for Australian backup-power records.
- UPS battery sizingEstimate required UPS battery capacity from entered load and runtime target. Inputs: Load, runtime target, DC bus voltage, efficiency and reserve allowance. Output: UPS sizing worksheet for Australian backup-power records.
Review before applying
Backup power calculator results are preparation records. Keep entered values beside current Australian requirements, DNSP or authority conditions, manufacturer information and project documents before applying a result.
Recheck the selected calculator whenever the supply arrangement, equipment data, route length, tariff basis, measurement method or project document set changes.
- UPS runtimeReview UPS runtime from entered battery energy and load assumptions.
- UPS battery sizingReview UPS capacity from entered load and runtime target.
- UPS runtime limitationsReview why runtime and sizing remain product-bound topics.
Backup power record notes project basis
Backup power calculators need extra project context before a result is applied. These calculators support Australian design, estimating, installation and verification preparation. Keep the circuit, equipment, route, supply arrangement and source data with the result before it is used in a project record.

Records covered
- Record note 1Backup power calculations usually depend on the load profile, runtime target, battery or UPS data and the way the equipment will be used during an outage. Keep those assumptions beside the calculator result so the record can be compared with product data and site expectations.
- Record note 2For Australian backup-power planning, the calculator result is only one part of the decision. Confirm the load category, runtime reserve, installation environment, charging arrangement, maintenance requirement and manufacturer documentation before carrying the number into procurement or design work.
Review before applying
Use these backup power notes beside the calculator input record, current project documents and competent Australian review.
Recheck the selected calculator whenever the supply arrangement, equipment data, route length, tariff basis, measurement method or project document set changes.
