What Data for This Category Looks Like
Data for energy storage industry financial reports comes from annual and quarterly financial reports of publicly traded energy storage enterprises, industry white papers released by industry associations, and completion acceptance documents for power station projects. Update schedules follow public disclosure rules. Annual reports are released per calendar year. Quarterly reports are published after the end of each quarter. Temporary announcements are updated synchronously with project progress. Document structures include fields such as project installed capacity, system integration cost, and charge-discharge cycle count. Common units include megawatt (MW), kilowatt-hour (kWh), yuan per watt-hour (yuan/Wh), and cycle count. Document length varies widely. Small project documents span tens of pages. Large power station project documents can reach hundreds of pages.
Constraints Imposed on Document Parsing and Chunking
Documents from multiple sources have significant format differences. They include structured financial report tables, unstructured project descriptions, and scenarios with embedded charts. This requires parsing workflows to support format adaptation. The wide span of document lengths imposes clear constraints on chunk granularity control and memory usage. Field units include multiple professional measurement identifiers. Accurate recognition is required to avoid parsing deviations. The sudden nature of temporary announcements requires parsing workflows to support rapid triggering. It also requires controlling single-file parsing time to avoid impacting overall service efficiency.
How to Configure Settings
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
PARSE_FILE_TIMEOUT_SECONDS | 600 seconds | Energy storage project documents range from tens to hundreds of pages. Large documents take longer to parse. 600 seconds covers parsing needs for most scenarios |
UPLOAD_FILE_MAX_SIZE | 1000 MB | PDF documents for large power station projects may include high-definition drawings. 1000 MB supports upload and parsing of such files |
maxChunkSize | 800–1200 characters | Energy storage financial reports include professional terminology and long sentences. Chunking at 800–1200 characters preserves context integrity and avoids splitting professional content |
chunkOverlap | 100–150 characters | Chunk overlap ensures contextual coherence for professional paragraphs and prevents key information from being split between two chunks |
PARSE_USE_PDF_MARKER | Enabled | Energy storage documents often include charts and complex layouts. pdf-marker better extracts text around charts and structured content |
RECALL_CHUNK_COUNT | Top 8 entries | Key information in energy storage financial reports is mostly concentrated in specific sections. 8 chunks cover the core information scope while avoiding redundant recall |
The parameter values provided on this page are common starting points for configuration. Actual values are affected by material form, data volume, and business rules. Specific issues require individual analysis. Testing on local samples is recommended before finalizing settings.
Three Common Mistakes
- Scenario: When using the Claude 3.7 model, normal chat functions operate correctly, but uploading energy storage financial report documents returns parsing failure or empty results. Cause: The
PARSE_USE_PDF_MARKERconfiguration is not enabled. This prevents adaptation to complex charts and layout structures in energy storage documents. - Scenario: The parsing process returns a
JSON parse errormessage, and logs show field parsing exceptions. Cause: Configurations for professional units in energy storage documents are not adjusted. This causes the parsing engine to fail to correctly identify identifiers such as MW and yuan/Wh, triggering JSON serialization failure. - Scenario: After locally deploying FastGPT 4.8.22, uploading energy storage financial report documents causes the file parsing function to fail. The interface shows parsing in progress but returns no results. Cause: The
UPLOAD_FILE_MAX_SIZEandPARSE_FILE_TIMEOUT_SECONDSparameters are not correctly configured during local deployment. This causes large files or long-duration parsing to be blocked by the system.
How to Confirm Correct Configuration
- Upload a typical document from the energy storage industry. Check that the parsed text fully extracts professional fields with no garbled characters or missing content.
- View system operation logs. Confirm that the parsing process does not trigger timeout errors and that the chunk generation logic matches configuration requirements.
- Upload energy storage documents of different sizes. Confirm that upload and parsing processes are not blocked by the system, matching the current configured file size limit.
- Trigger multiple large file parsing requests. Confirm that the system completes processing according to the configured timeout parameters with no abnormal interruptions.
