    Solar Inverter Grid Frequency PLL Lock Drift Audit

    Example session with this skill installed

    Case: Solar inverter repeatedly derates during otherwise normal grid operation.

    Provided: inverter PLL phase error and power quality meter frequency traces (illustrative, partial). Potential exception: phase locked loop filtering overreacts to harmonic content on feeder. Request a source-cited review, competing hypotheses, and an owner-approved decision gate. Do not execute changes or assert unsupplied facts.

    Solar Inverter Grid Frequency PLL Lock Drift Audit — SYNTHETIC EVIDENCE-LIMITED REVIEW

    Case received

    Solar inverter repeatedly derates during otherwise normal grid operation.

    Evidence register

    • S1: inverter PLL phase error and power quality meter frequency traces — PARTIAL / UNVERIFIED.
    • S2: approved operating baseline / documented policy — NOT PROVIDED; REQUIRED TO VERIFY.
    • S3: timestamped revision or change record — NOT PROVIDED; REQUIRED TO VERIFY.
    • S4: accountable reviewer and approval evidence — NOT PROVIDED; REQUIRED TO VERIFY.

    Investigation checks

    1. Establish the identity, timestamp basis and revision lineage of inverter PLL phase error and power quality meter frequency traces; document missing or contradictory records. — PENDING CORROBORATION.
    2. Reconstruct the event sequence surrounding phase locked loop filtering overreacts to harmonic content on feeder, citing exact record identifiers and independent checks. — PENDING CORROBORATION.
    3. Compare the evidence with the approved baseline; test the competing explanations for: Solar inverter repeatedly derates during otherwise normal grid operation. — PENDING CORROBORATION.
    4. Draft a non-executing, owner-approved validation sequence and rejection criteria for licensed grid engineer event classification and protection tuning review. — PENDING CORROBORATION.

    Deliverables

    • time-aligned evidence index for inverter PLL phase error and power quality meter frequency traces: DRAFT / INCOMPLETE until inputs are validated.
    • exceptions and alternative hypotheses for phase locked loop filtering overreacts to harmonic content on feeder: DRAFT / INCOMPLETE until inputs are validated.
    • approval-gated licensed grid engineer event classification and protection tuning review and verification criteria: DRAFT / INCOMPLETE until inputs are validated.

    Decision gate

    INCOMPLETE — HUMAN REVIEW REQUIRED. Sources, scope, time basis and sign-off remain unverified. No live change or approval has occurred.

    About this skill

    Solar Inverter Grid Frequency PLL Lock Drift Audit is a ToolForge Labs OpenClaw Skill evidence-review workflow. Reconcile converter lock loss with external grid reference recordings.

    What this skill checks

    1. Establish the identity, timestamp basis and revision lineage of inverter PLL phase error and power quality meter frequency traces; document missing or contradictory records.
    2. Reconstruct the event sequence surrounding phase locked loop filtering overreacts to harmonic content on feeder, citing exact record identifiers and independent checks.
    3. Compare the evidence with the approved baseline; test the competing explanations for: Solar inverter repeatedly derates during otherwise normal grid operation.
    4. Draft a non-executing, owner-approved validation sequence and rejection criteria for licensed grid engineer event classification and protection tuning review.

    What to provide

    • inverter PLL phase error and power quality meter frequency traces
    • approved operating baseline / documented policy
    • timestamped revision or change record
    • accountable reviewer and approval evidence

    Deliverables

    • time-aligned evidence index for inverter PLL phase error and power quality meter frequency traces.
    • exceptions and alternative hypotheses for phase locked loop filtering overreacts to harmonic content on feeder.
    • approval-gated licensed grid engineer event classification and protection tuning review and verification criteria.

    Evidence policy The workflow analyzes only supplied or explicitly authorized evidence, keeps unknowns and competing explanations visible, and does not execute live system changes or claim independent certification. An authorized owner must approve operational decisions.

    Find more skills like this on the Claude Skills Marketplace, the Codex Skills Marketplace and the Gemini Skills Marketplace, or browse Claude Skills for Agents & Orchestration.

    No live validation or direct platform access is asserted. Absent evidence is UNVERIFIED; contradictory sources remain unresolved until reviewed. Only authorized owners may approve real-world actions.

    What's inside

    Frequently Asked Questions

    This skill identifies whether an inverter disconnect was caused by a genuine grid fault or by the inverter's Phase Locked Loop (PLL) overreacting to minor harmonics, helping to prevent unnecessary energy production losses.

    It is compatible with standard CSV or JSON telemetry exports from major manufacturers like SMA, SolarEdge, and Sungrow, alongside IEEE 1159 compliant power quality meter data.

    The skill is a configuration for AI agents; you simply upload your historical telemetry logs to the agent's workspace to begin the automated reconciliation and event mapping.

    You receive the specialized engineering logic for frequency auditing, a structured reporting template, and a standardized evidence-labeling framework for licensed engineer review.

    The skill includes a 'Validation Drafting' feature that generates specific rejection criteria, allowing a licensed professional to quickly verify the AI's findings against local grid codes.

    No, this skill is designed for historical forensic analysis; it requires pre-exported telemetry files and does not provide real-time monitoring or control capabilities.
