Microgrid & Distributed Energy Equipment worked example
Inverter Cabinet Capacity at 99% line uptime: a worked example
Push line uptime up to 99% and the picture changes. This example computes every intermediate figure at that operating point. Use it when an inverter or PCS cabinet build line is asked to absorb more microgrid and distributed energy orders and you need to know whether there is room in the schedule.
The inputs for this scenario
- Inverter cabinets finished per cycle: 4 cabinets / cycle (unchanged)
- Available build cycles: 480 cycles (unchanged)
- Line uptime: 99 % (raised for this scenario; the documented default is 90)
- First-pass test yield: 97 % (unchanged)
Working through the calculation
- Applying the documented formula (Gross inverter cabinet capacity = inverter cabinets finished per cycle × available build cycles) to the inputs above produces each figure below.
- At this operating point the engine returns 1,844 cabinets for good inverter cabinet capacity, the number this scenario is built around.
- At this operating point the engine returns 1,920 cabinets for gross inverter cabinet capacity.
- At this operating point the engine returns 19.2 cabinets for inverter cabinet capacity downtime loss.
- At this operating point the engine returns 57.02 cabinets for inverter cabinet capacity yield loss.
How this compares with the baseline
- Against the tool's baseline example, where line uptime sits at 90% and the headline result is 1,676 cabinets, this scenario comes in 10% above the baseline at 1,844 cabinets.
- It computes good (sellable) inverter cabinet capacity by derating gross cycle output for line uptime and first-pass test yield, and breaks out the downtime and yield losses. 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.
