Renewable Energy, Solar & Wind Manufacturing worked example

Inverter Test Time at 12% setup, handling, and dwell allowance: a worked example

Push setup, handling, and dwell allowance up to 12% and the picture changes. This example computes every intermediate figure at that operating point. Use it when inverter test time in renewable energy, solar and wind manufacturing is changing rate or allowance and you want to see the impact.

The inputs for this scenario

  • Inverters to burn-in and test: 120 units (unchanged)
  • Test-cell throughput rate: 12 units / min (unchanged)
  • Setup, handling, and dwell allowance: 12 % (raised for this scenario; the documented default is 10)

Working through the calculation

  • Applying the documented formula (Base inverter test time = inverter test time workload รท inverter test time completion rate) to the inputs above produces each figure below.
  • At this operating point the engine returns 11.2 hr for required inverter test time, the number this scenario is built around.
  • At this operating point the engine returns 10 hr for base inverter test time.
  • At this operating point the engine returns 12 % for inverter test time allowance applied.
  • At this operating point the engine returns 12 pieces / min for inverter test time completion rate.

How this compares with the baseline

  • Against the tool's baseline example, where setup, handling, and dwell allowance sits at 10% and the headline result is 11 hr, this scenario comes in 1.82% above the baseline at 11.2 hr.
  • Computes the total test-cell hours for a batch of inverters, including a setup and handling allowance on top of raw test throughput. The value of this scenario is the size of the gap it exposes: that gap, priced out over a year, is the budget you can justify spending to close it.

Results at a glance

  • Required inverter test time: 11.2 hr (headline result)
  • Base inverter test time: 10 hr
  • Inverter test time allowance applied: 12 %
  • Inverter test time completion rate: 12 pieces / min
