Some prosumer schemes only allow a household to sell energy its own PV produced (e.g. Poland: grid energy stored in a battery may not be resold). export_budget_mode in apps.yaml limits forced battery export to that energy: - pv_origin: stored energy is split into a PV part and a grid part; battery output up to the on-site load draws the grid part first, only the PV part may be force exported. - pv_equivalent: a bucket filled by PV production and drained by all export (capped by export_budget_cap_kwh, default the battery size). The rule lives in export_budget.py and is mirrored by both prediction engines (kernel ABI 8, parity 18). Each cycle the budget is seeded by replaying 7 days of pv/export/import/load history (and battery SoC for pv_origin). Export targets are raised so the inverter, which exports at full power down to the target, can never sell more than the budget allows, both when clipping a new plan and every cycle for the export running now. predbat.export_budget publishes the budget now and over the best plan. Off by default; with the mode off nothing changes. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
Cross-built with build_kernel_cross.sh and zig 0.16.0 (as in CI) for ABI 8 / parity 18. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
- export_budget_cap_kwh was read with an int default, so get_arg truncated 7.1 to 7. - soc_kw history for the pv_origin replay is now scaled by battery_scaling, as the live SoC is. - export_budget_mode: off unquoted is YAML false; the schema accepts it. - Docs: the replay length follows the history days_previous loads.

Brings springfall2008#5538 into the fork's
main: optional export energy budget that only lets the battery export energy that came from PV (export_budget_mode: off | pv_origin | pv_equivalent).The description, testing and review discussion live in the upstream PR. This PR uses the same branch (
pr/export-energy-budget).On the fork,
mainis upstreammainplus the patches not yet merged upstream, rebased onto upstreammainon every sync. When springfall2008#5538 is merged upstream, its commit is dropped from the fork'smainduring the next rebase.Like springfall2008#5429 (fork PR #2), this changes the prediction kernel's
PkContextand its ABI/parity numbers. With both on the fork'smain, they need one combined numbering and rebuilt kernel binaries, in a separate commit after both.🤖 Generated with Claude Code
