Summary

  • Charge/discharge slot times are written to the Solis inverter as plain HH:MM values with no timezone attached, so the inverter interprets them using its own configured timezone rather than Predbat's.
  • A mismatch (e.g. inverter left on UTC while Predbat runs Europe/London) shifts the resulting charge/discharge windows by the difference - most visibly a full hour out whenever BST is in effect.
  • Documents the requirement that the inverter's own timezone be set to match Predbat's timezone setting.

Ref: #4448

Test plan

  • Docs-only change, mkdocs.yml unaffected (existing page)
  • ./run_pre_commit passes (markdownlint, cspell)
