What is string planning?

String planning is the electrical connection of solar modules to strings for connection to inverters. It determines the number of modules, voltage and amperage per module row. Correct string planning maximizes yield and prevents technical problems. Factors such as module type, inverter compatibility, and installation conditions are considered.

How does string planning work with autarc?

autarc automates the entire string planning based on your module assignment. The software calculates optimal string configurations and checks all technical parameters in real time. You will receive immediate feedback on the feasibility and efficiency of your planning. Inverter data is automatically included and individual MPPT settings are taken into account.

  • Schritt 1: Module per Drag & Drop verschalten
  • Schritt 2: Live-Prüfung aller Parameter
  • Schritt 3: MPPT-Optimierung

Benefits of string planning with autarc

  • Fehlerfrei planen: Automatische Prüfung verhindert Rechenfehler und technische Probleme.
  • Zeit sparen: Keine manuellen Berechnungen mehr – alles wird automatisch optimiert.
  • Live-Feedback: Sofortige Rückmeldung zu Spannung, Strom und Wechselrichterkompatibilität.
  • Temperatur-Berücksichtigung: Außentemperatur und Installationsart fließen in Berechnung ein
  • MPPT-Flexibilität: Individuelle Einstellungen pro Maximum PowerPoint Tracking (MPPT) für optimale Ausnutzung.
  • Integrierte Lösung: Direkt verknüpft mit Dachplanung und Angebotserstellung.

Which features are included?

planning

Easy string planning

Intuitive connection by clicking or dragging the modules. The software automatically recognizes optimal string configurations and suggests the best solution. Manual adjustments are possible at any time.

MPPt

Flexible MPPT settings

Inverters can be assigned individual values per MPPT, which are automatically taken into account when planning strings. This maximizes the efficiency of every single MPPT input for optimal yield.
