    <p>Vzal jsem spotřebu po dnech za poslední rok, odběr v kWh v každém
      dnu a povolil maxiální odběr nabíječe aku cca 5 kW (mám 3x25A, ale
      cca 3x 7A bude v zimě po tu dobu brát tepelné čerpadlo + nějaká
      rezerva) a získal tak počet hodin každý den, kdy by se aku
      nabíjel. Vzal jsem po tuto dobu vždy příslušný počet hodin s
      nejnižší spotovou cenou a výsledek je tato tabulka (srpen není
