Introduction to Inverter Technology


Sunny Design contains the most important data of all SMA inverters as well as all cur- rently available PV modules. It is easy to use and guides the planner through the entire design process. This saves time and allows different configuration options to be simulated without the need for complicated calculations. Sunny Design calculates the values automatically and comes up with a comprehensive result for all design vari- ants.


Operating states that could be critical are reliably detected and identified. This ensures that the planner is notified of any deviations from the standard design. Such a notification does not necessarily mean that the design is not permissible, but it serves to indicate that a thorough check is required to see whether this operating state (e.g. gen- erator voltage too low) is relevant in the current plant.


Sunny Design thus enables the plant de- signer to fully concentrate on what plant designing is all about. The software helps to estimate the implications of the most im- portant parameters on the yield and invest- ment costs. In this way, the customer can be offered a tailor-made plant.


Additionally, realistic operation is evalu- ated over a calendar year on the basis of the integrated meteorological database. Although an accurate yield forecast can- not be expected from Sunny Design (further simulation programs with complex adjust- ment possibilities are necessary for this), Sunny Design can determine the yield dif- ferences between the different designs and also includes technical checking. Thus not only can the best plant design be found, it can also be evaluated how cost-effective it is.


Finally, the technical assessment of the plant design is illustrated clearly in a results report that can be individually customized. As a printout or a PDF file, this summary is the ideal supplement to an offer.
