Stage 12 of 13 / Commissioning

Commission and verify

Define the tests that prove the installed system matches the design, and the measurements that would falsify it.

Development preview. The calculations on this journey run on existing EngiMetric engines, but the journey text and scope have not completed independent engineering review. The route is excluded from search while it remains a preview.
Professional review required.The engines are implemented and unit-tested in this repository, but the journey copy, defaults and boundary still require review by a licensed engineer before publication. The route remains a noindex preview. Current verification state: Needs engineering review.

After this stage you can

Learning objectives
  • Name the electrical and energy tests that prove the design.
  • Set acceptance criteria before seeing the measurements.
  • Explain why an as-built change requires a re-run of the model.

The engineering

Commissioning is not a visual inspection. It is a set of measurements with acceptance criteria: insulation resistance, polarity, open-circuit voltage per string, short-circuit current, earth continuity, inverter configuration, battery capacity test and a monitored energy balance.

The design predicts specific yield, self-consumption and unserved energy. Commissioning should compare measured values with those predictions and investigate a material gap instead of explaining it away. A performance ratio far below the screen is evidence of a problem, not weather noise.

Record the as-built configuration. If the installer changes a string length, a breaker or a dispatch setting, the report must be re-run. The commissioning checklist is deliberately a template: the project team owns the instruments, calibration and signed results.

Stage assumptions, limits and sources

Provenance

Assumptions

  • Test instruments are calibrated and operated by competent personnel.
  • Acceptance criteria are agreed with the client and the installer.

Constraints

  • No measured test data is generated or stored by the workbench.
  • No grid-code or utility commissioning witness procedure is included.

Limitations

  • The checklist is not a commissioning method statement or a safety procedure.
  • No performance guarantee, liquidated damages or long-term monitoring plan.

Review status

  • Needs engineering review
  • Professional review is required before publication or use as a design basis.
