+## Planner v2
+
+Tahle sekce popisuje návrh druhé verze planneru. Cíl je mít samostatný solver, který bude vycházet ze stejného vstupu a bude zapisovat do stejného `planning_interval`, ale provozní pravidla budou čitelné a striktně dané zadáním.
+
+### Význam hranic SoC
+
+- `reserve_soc_percent` = ranní cílová hranice, na kterou se má baterie dobít, pokud to denní forecast a ceny umožňují
+- `min_soc_percent` = fyzická / TOU podlaha, pod kterou baterie nesmí klesnout
+- `reserve_soc_percent` je tedy provozní kotva pro den, zatímco `min_soc_percent` je tvrdé minimum
+- `reserve_soc_percent` není predikce noční spotřeby; jen znamená „než začne export z FVE do sítě, drž baterii aspoň sem“
+
+### Základní pravidla v2
+
+#### Ráno
+
+- pokud denní forecast dává dostatek výroby nebo levných hodin, planner dobije baterii minimálně na `reserve_soc_percent`
+- tato rezerva slouží jako ochrana proti neplánované spotřebě během dne
+- `min_soc_percent` se v ranní fázi nepoužívá jako cíl, ale jen jako spodní limit
+
+#### Záporná nákupní cena
+
+- při `buy_price < 0` má prioritu nabíjení ze sítě
+- cílem je uložit levnou energii pro pozdější dražší prodej
+- to ale neznamená, že se má baterie dobít hned v první záporné hodině; pokud jsou v horizontu ještě zápornější ceny, může být lepší nabíjet později
+- nabíjení ze sítě je omezené jen fyzickými limity baterie a připojení
+
+#### Záporná prodejní cena
+
+- při `sell_price < 0` je export do sítě zakázán
+- řiditelná FVE A se může škrtit
+- neřiditelná FVE B se neškrtí, pouze se povinně zohlední v bilanci
+- baterie se nejdřív nabíjí z přebytku FVE, potom se využije flexibilní spotřeba
+- pokud je potřeba uvolnit místo pro pozdější extrémně záporné ceny, může planner baterii předem záměrně mírně vybít až na bezpečnou ekonomickou podlahu
+
+#### Nezáporná prodejní cena
+
+- věta „prodám vše“ v tomto návrhu neznamená povinné okamžité vybití baterie
+- znamená pouze to, že pokud je baterie už plná z levných nebo záporných hodin, přebytek FVE A jde do sítě
+- pokud ještě dává větší smysl uložit energii pro pozdější dražší prodej, má přednost uložení do baterie
+- dynamické zátěže jako TUV a wallbox zůstávají plně součástí bilance; jejich spotřeba může být využita jako další „úložiště“ levné energie
+
+#### Prodej z baterie
+
+- při cenové špičce má baterie prodávat do sítě
+- v2 má využít baterii jako arbitrážní zásobník mezi levnými a drahými okny
+- vybíjení nesmí klesnout pod `min_soc_percent`
+
+#### PV A a PV B
+
+- PV A je řiditelná a může být curtailovaná
+- PV B je neřiditelná a nikdy se neplánuje jako curtailovaná výroba
+- PV B je vždy pevný vstup do bilance
+
+#### BA81 / GEN cutoff
+
+- v lokalitě BA81 může být zapnutý `deye_gen_microinverter_cutoff_enabled`
+- pokud by při záporné prodejní ceně nebo no-export politice vznikal nežádoucí export z GEN portu, planner v2 musí umět aktivovat cutoff mikroinvertoru
+- cutoff má být součást rozhodnutí planneru, ne dodatečná heuristika v exporteru
+
+### Co má být v plánu zapsané
+
+Planner v2 má do `planning_interval` zapisovat stejné základní položky jako dosavadní verze:
+
+- `battery_setpoint_w`
+- `battery_soc_target_pct`
+- `grid_setpoint_w`
+- `export_limit_w`
+- `export_mode`
+- `deye_physical_mode`
+- `deye_gen_cutoff_enabled`
+- `pv_a_curtailed_w`
+- `expected_cost_czk`
+- `effective_buy_price`
+- `effective_sell_price`
+
+### Implementační oddělení od v1
+
+- v1 zůstává beze změny
+- v2 bude samostatný modul planneru
+- přepnutí mezi v1 a v2 bude na úrovni orchestrace nebo konfigurace lokality
+- exportér i control pipeline mají dál číst standardní výstup z `planning_interval`
+- pokud je zapnuté `PLANNING_ENGINE_COMPARE_ENABLED`, backend spočítá obě verze nad stejným vstupem, aktivní verzi zapíše do plánu a druhou uloží i jako samostatný read-only `planning_run` se stavem `comparison`
+- compare čtení jde přes `GET /api/v1/sites/{site_id}/plan/compare` a endpoint páruje compare run na aktivní run přes `comparison_of_run_id`
+- FE stránka `frontend/src/pages/Planning.tsx` ukazuje souhrn aktivní verze, compare verze, slotové rozdíly a compare křivku baterie v grafu
+- fyzicky se na střídač aplikuje jen aktivní plán; compare běh slouží jen pro audit a vizualizaci
+
+### Shrnutí v jedné větě
+
+Planner v2 má dělat přesně toto:
+
+- ráno držet baterii na `reserve_soc_percent`
+- při záporných nákupních cenách nabíjet ze sítě
+- při záporných prodejních cenách zakázat export
+- při cenových špičkách prodávat z baterie
+- PV A škrtit jen když je to nutné
+- PV B nikdy neškrtit
+- BA81 řešit přes GEN cutoff
