- arbiter: a mode now gives way only as far as a site limit above P_MODE
needs (_unit_modes at N>1, _site_mode at N=1). Before, the modes were
released only when the peak floor bound S, so a trade won above the floor
kept them and placed less than the floor (an Off battery at N=1 went to 0 W
under a 2000 W floor), and a capped grid charge released an Off battery.
While released, held batteries weigh 0 and carry only the shortfall.
- control: a side of the loop bound that reaches the rail is left to the
rail, so SAFETY-03's i_clamped still fires with every battery on.
- opt11_identity: add maintenance scenarios and a 6000-case arbiter digest
(peak floor, trades, maintenance, refusals); a5dddad digests pinned.
- tests: test_arbiter part 11, test_control (g), test_modes (0/1 refused,
loop bound counts live units only). DOCS and DECISIONS say the new rule.

# OPT-11 - battery modes, per battery
|
|
|
|
A battery's mode (on/off, Solar first, Leftover solar) is a soft unit limit at
|
|
`P_MODE` = 35 that always holds 0 W. A SET above 35 (a safety stop) overrides
|
|
it; a limit above 35 (the peak guard) makes it give way only as far as that
|
|
limit needs, and a battery its mode holds back then carries only what the
|
|
others cannot (`arbiter._unit_modes()`, `_site_mode()`). Design and owner answers: `goodwe-session/OPT-11-design.md` (2026-09-27);
|
|
P1 is its section 6 P1, and the pull request lists what was measured.
|
|
|
|
- Off by default (`battery_modes_enabled`); off, commands are byte-identical to
|
|
a5dddad (`test_modes.py` part 1).
|
|
- Off is a mode range, so the peak guard can still use an Off battery when the
|
|
others cannot cover the floor (design sections 2-3). Whether Off should be
|
|
absolute is an open owner question.
|
|
- Review (PR #149): releasing only when the peak floor bound S let a trade won
|
|
above the floor keep the modes and place less than the floor, and let a
|
|
capped grid charge release an Off battery. Both are graded in
|
|
`test_arbiter.py` part 11. The loop bound leaves a side that reaches the
|
|
rail to the rail, so SAFETY-03 still flags a loop winding into it.
|
|
- In P1 only Off closes a direction; Leftover solar differs by charging last.
|
|
Price runs, selling (`pack_sell`, reserved) and the forecast are P3/P4.
