Improvements and fixes

On-site analyses now keep every string result and pick up component changes immediately, and SMA inverters stay on one connection.

• After an on-site analysis on a large plant, every string keeps its result; a few hundred of them no longer go missing.
• Changes you make to a plant's components take effect in the on-site analysis you start right after, instead of up to an hour later.
• Your SMA inverters no longer switch back and forth between the plant controller and their own data logger.
