Ik laad en ontlaad via Battery Max Charge Current en Battery Max Discharge Current in zelfconsumptie modus. Het draait deze week als test en ik ben zeer tevreden over de resultaten.
Ik heb samen met Gemini een hele automatisering gemaakt met als doel NOM met o.a. een failsafe ter bescherming van de 3 fases (max current 23A), de accu beschermen tegen onnodige cycli, met PI (nee er is geen D), Deadband en EMS spread via schuifregelaars. Zelfs een digitale noodstop, zodra de switch uitgaat stopt de automasering automatisch.
Ik zal vanavond de automasering, templates en helpers hier delen.
Vandaag versie 4 met Gemini gemaakt, de afgelopen dagen heb ik allemaal kleine tweaks toegepast.
Even een korte samenvatting: woning uit 1962 met 3x25A en gasloos, 3900Wp zonnepanelen (180°), verwarming middels 7 kW pellet kachel, 15 kW Nexus thuisbatterij van Zonneplan, Quooker in de keuken, warm water badkamer via 120l elektrische boiler, koken op keramische kookplaat.
Met deze gegevens ben ik met Gemini aan de slag gegaan. De dongels van ZP zitten nog gewoon in de accu en hij staat in de modus zelfconsumptie. P1 meet ik via HomeWizard.
Sinds afgelopen zondagmiddag draait de automatisering en mijn verbruikskosten in de app van ZP zijn als volgt: zondag +€ 1.95, maandag -€ 0.85, dinsdag + € 0.41 en vandaag - € 0.52.
5 helpers:* input_boolean.nexus_batterij_failsafe
* input_number.nexus_pid_kp (min 0, max 2, step 0.05)
* input_number.nexus_pid_ki (min 0, max 0.2, step 0.005)
* input_number.nexus_em_spread (min 0.05, max 0.5, step 0.01)
* input_number.nexus_pid_deadband (min 0, 250, step 5, unit W)

mode: restartGemini heeft er her en der wat toelichting ingezet i.v.m een aantal aanpassingen.
In verband met de Quooker en de kooplaat hebben we er een filter ingebouwd die er voor zorgt dat het niet zo'n zaagtand situatie wordt. Indien gewenst kan ik de grafieken van de P1, PID en SoC van de afgelopen dagen delen.
Heb je aanvullingen of verbeteringen? Ik hoor het graag! En zoals altijd, gebruik van de code is op eigen risico!
