UPS / Inverter Battery Capacity Verification Checklist PDF

Full QC Checklist+

Verify load input accuracy, battery configuration/depth of discharge, runtime/sizing calculation, and installation/safety.

✓21 Inspection Points

✓4 Verification Categories

✓Load Input Accuracy+

Actual nameplate/rated watts used for major equipment, not guessed from a generic chart
All equipment you actually intend to keep running is included, including easy-to-forget items
Motor-driven, cycling loads (refrigerator, sump pump) flagged as producing a variable, not perfectly steady, draw
Quantity field used correctly for repeated items, not double-counted as separate identical rows
Non-essential loads excluded, rather than listing everything in the house "just in case"

✓Battery Configuration & Depth of Discharge+

Battery chemistry selection matches the actual battery type purchased or planned
Planned usage confirmed not to regularly discharge the battery beyond its recommended DoD
Series/parallel wiring configuration confirmed against the actual battery's voltage rating
System voltage confirmed against the inverter/UPS's actual DC input requirement
Aging/end-of-life margin considered appropriate for the expected battery lifespan and how it will be used

✓Runtime / Sizing Calculation+

Correct calculation mode selected for the actual planning question being asked
Efficiency percentage reflects the actual inverter/UPS's rated efficiency, not left at a generic default
In Sizing mode, the actual achieved runtime (not just the target you entered) confirmed adequate
Understood that motor-driven/cycling loads' real-world backup time can differ from this steady-load estimate
Runtime and Sizing mode results cross-checked against each other where practical

✓Installation & Safety+

Battery placement and ventilation confirmed per the manufacturer's guidance
DC-side wiring and cable gauge sized for the actual current draw, not just the AC-side circuit
Overcurrent protection (fuse or breaker) confirmed on the battery bank, sized for the DC circuit
Inverter/UPS VA rating cross-checked against the actual connected load, not assumed automatically adequate
Permanent or whole-panel backup installation reviewed by a licensed electrician
Battery disposal/recycling plan confirmed per local regulations at end of life

Inspection Notes+

Use the latest approved drawings, specifications, and site measurements.

Complete all critical checks before proceeding to the next work stage.

Record deviations and confirm rectification where required.

Record deviations and confirm rectification where required.

Use it after collecting the project inputs and again before approving or closing the relevant work stage.

No. It supports verification but does not replace approved drawings, specifications, codes, manufacturer requirements, or professional inspection.
