I made a small parser of emap log files for Huawei Sun2000. Please test it. It helps to analyze failures in work.
Thanks for the feedback.

I kindly ask you to upload your data - it will help a lot in improving the program
Thank you

https://andysu3.mooo.com/hua3/env3 is comin' ! - at 24/04/26
still trying to use free coders to the max (there are still alternatives to qwen, luckily))

1 - added Huawei by serials check - here is a little explanation - Huawei (at least here)behaves with a warranty like this - when there is a warranty - equipment replacement without problems (checked - they even paid for the transfer),when there is no warranty - they don't do off-warranty repairs at all. They only offer to extend it before the end of the off-warranty.Therefore - I think - it's better to control here. Also - pay attention to the country of service - there may be no service.
2 - added documentation on error codes.
3 - beta testers are really needed - please come and test

big update!

Big Parsers Update Today

Today is a big update for the parsers. Here are the details:

### Support for new log types added

The capabilities of the system have been significantly expanded, now decrypting files that were previously ignored:

• Critical and active alarms (alarmg_major, alarmg_active) — information about the most important accidents in the ESS (Energy Storage System) is now available.
• LUNA2000 battery logs (bmu_alarm_log) — added support for diagnostics of battery blocks.
• Universal performance (perfmg) — the system learned to understand any performance variations: hourly, daily, monthly, as well as old SmartLogger formats (his_per_data).
• Alternative inverter logs (his_inv_data, his_fan_data) — added support for operating parameters for large industrial ESS systems.
• New panel inspection format (sun_inspect_rec) — decoded a new extended format of IV-curve diagnostics, which differs from the classic panel passport.
• Text and debugging data (text_log, sun_dbg_info) — the system now automatically sorts standard text reports and decrypts inverter system debugs.
• Memory (RAM) optimization — all parsers have been ported to streaming processing, reducing server RAM consumption by tens of times when processing massive log archives.

### Bug Fixes

• Missing data: Fixed an issue in the main log (his_inv_rd) where significant data arrays were lost (in some cases, up to 90% of records were missing).
• SmartLogger compatibility: Fixed device recognition logic, due to which internal communications (dsp_log) and oscillograms (dsp_wave_data) from SmartLogger were not read by the parser.
• Column shifting: Repaired "broken" column shifts in dsp_log reports, which caused some values to end up in the wrong cells.

### Improved Report Quality (Usability)

• Code decryption: Added translation of many numeric codes into text format (statuses, alarm names, etc.).
• More details: From settings (cfg_file_ctrl), a full dictionary of parameters is now extracted (previously only a part was extracted), and voltage and current now have the correct scale (divided by 10 or 100 to show actual Volts and Amperes).
• New metrics: In oscillograms (dsp_wave_data), calculations for average values and phase imbalance were added, and in communication logs (dsp_log), indicators of insulation resistance and grid disconnection reasons appeared.

All these updates have successfully passed mass testing on a database of over 450 real files.

Wellcome!

and please - check your files - this help me to teach AI )))

12/08/26

A new platform update has been published. Key changes:

• Security: Added request rate limiting, CSRF protection, and additional checks to prevent Path Traversal and RCE vulnerabilities.

• I-V Curve Analysis: Added tools for string diagnostics. The parser calculates the Fill Factor, detects steps, and identifies open-circuit voltage drop

(Voc-drop). We also implemented current and voltage point extraction for charting.

• Authorization: Configured Google Sign-In. Basic parsing features remain available without registration, while advanced analysis has been moved to the

authorized users' zone.

• Localization: Completed translation of the interface and reports (available in Ukrainian, English, and Chinese).
