Design and simulation program for off-grid systems

Designing and planning off-grid systems can be challenging and time-consuming. Whether it’s for a small residential system or a large hybrid plant, the new SMA Off-Grid Configurator provides users with a customizable, professional solution for planning off-grid systems that saves time and money. Each design aspect is carefully analyzed, from sizing the PV array, battery and inverter, to a final cost analysis, providing the user with comprehensive planning assistance. The Off-Grid Configurator supports SMA off-grid systems worldwide, including both 230 V and 120 V systems.

  • New start page
  • Menu items/pages have been extensively revised and more neatly arranged:
    • Menu Consumption
    • Menu Inverter
    • Menu Auxiliary Generator
    • Menu Sunny Island and Battery
  • Menu Plant Type and Surrounding Area
    • Presentation of plant diagram with/without auxiliary generator
    • Display Climate Data
  • Menu PV Modules:
    • The term "Azimuth" has been replaced by the term "PV Module Orientation"
    • Orientation even for elevated PV modules is freely selectable.
    • Percentage data regarding shading (annually) occurrences can be made available
    • The term "Solar Savings Fraction" is replaced by the term "Desired Ratio to Consumption": The ratio of the amount of input energy contributed by a solar energy system to the total input energy required for a specific application
  • Simulation:
    • The result output as CSV has been extended to the following: low-power battery mode and charging strategy
    • After stopping the simulation, the following message pops up from the MessageBox: "Check the Message Window"
    • Warning/Indication when a change of battery is required or during operation in the low-power battery mode
  • Menu Results:
    • The term "Theoretical Consumption" is replaced by the term "Predefined Consumption"
    • The term "Consumption Simulation" is replaced by the term "Saved Consumption"
  • New contents were added to the online help/manual
  • Menu Options:
    • Regional settings during first initialization possible
  • Update database:
    • Battery database has been updated
    • Generator database has been updated
