Issue:
What is the usable file storage capacity on the PM8000 meter’s internal FTP/SFTP site?

Product Line:

PM8000 series meter

Environment:
PM8000 internal FTP/SFTP site
PM8000 default and custom webpages
PM8000 COMTRADE disturbance files

Cause:
The PM8000 provides onboard file storage accessed via FTP/SFTP for items such as COMTRADE disturbance files and meter webpages. The exact user‑accessible capacity is not specified in the standard user documentation and can vary by firmware and reserved system space.

Resolution:

1. Understand what is stored on the FTP/SFTP site. The meter can generate COMTRADE disturbance files and stores them on its internal SFTP site; default and custom webpages are also managed here.
2. Note total onboard storage context. Product materials indicate onboard data/event storage is present on the meter; however, the precise portion exposed as user‑writable FTP/SFTP space is not stated in the user manuals and may vary by build.
3. Verify usable capacity on your device.
   3.1 Connect to the meter via SFTP using an SFTP client and review any free‑space indicator provided by the client, if available.
   3.2 Use the meter webpages (Diagnostics/Statistics, where available) to review storage usage.
   3.3 Optionally perform a controlled upload test with known file sizes to determine practical free space, then remove the test files.
4. To maximize available space for custom webpages or files, remove unused custom webpages and other unneeded content from the /web folders via SFTP using the documented upload/delete workflow.
5. If a formal capacity figure is required, request an official statement for the specific firmware version from the product team, or validate on a representative meter as in step 3.
