Simplified creation of new time windows for EV usage profiles. Input of a consumption power limit for peak load shaving of the battery system.
Export of all energetic and economic key figures as csv file. Automatic calculation of current electricity purchase costs using load profile and purchasing tariff. Input option for Sunny Design Pro activation codes.
Improved management of alternatives. Extended display of details for thermal components. Numerous additional small product improvements. Release Notes Sunny Design Web 4. In PV projects with self-consumption, an e-vehicle and a charging station can be configured as a special load Templates of typical scenarios are included Important key figures are also presented E-mobility in the commercial sector: Multiple charging stations are supported as part of the system Two options for specifying the energy demand of e-mobility, including templates: Fixed user group and known vehicle types as in the case of multi-family houses or defined fleets Statistical usage of the charging station with unknown user groups supermarkets, hotels Additional improvements Single-family homes available for energy system projects Numerous pre-defined building types are supported Allows the thermal energy demand to be estimated when the actual consumption is not known Manual dimensioning of the thermal energy storage system Also: Sunny Tripower Storage 60 is covered.
Release Notes Sunny Design 3. Load profiles with a time period of seven days can also be imported now. The data are then automatically rounded up to an entire year. The usable battery capacity of the storage system can now be changed for off-grid projects. For the THD calculation the input value of the connectable feed-in power is now validated to prevent miscalculations.
For hybrid projects the total minimum load of the gensets is now shown in the project documentation. New Sunny Design tutorial videos have been incorporated on the landing page and the personal dashboard. An error when calculating solar fractions of heat pumps was rectified.
The import of load profiles from CSV files was improved. An unnecessary status icon of the nominal power ratio was removed in the project documentation. Additional minor error corrections and product improvements.
Sunny Design also supports smart modules with Tigo TS4 components. The effects of the various TS4 products on system design and yield estimation are taken into account. New inverters: SB3. The new version also contains various minor improvements and bug fixes. The limitation of the active power feed-in at the grid-connection point is now being supported by the SMA Cluster Controller.
The integration of a heat pump into the energy management of the Sunny Home Manager can now be simulated. Designs with central inverters also comprise information about SMA system technology. The project documentation has been extended to include a page regarding cable dimensioning. The profitability analysis now also includes the storage system costs, annual rate of return and LCOE. Projects can be hidden on the start page via the user settings e.
Improved presentation of the power tolerance of PV modules. Manual input of battery efficiency. Improved update dialogue regarding the Sunny Design desktop. Different minor improvements and corrections bug fixes. SDPA for the simultaneous export or import of several projects Improvements in the data synchronization Numerous additional improvements and bug fixes.
These projects are identified in the overviews by corresponding symbols. In the project data it is now possible to enter active power limitation specifications manually within a wide setting range. In projects with self-consumption, the Sunny Home Manager can be used to limit active power, e. This is also taken into account in the yield forecast.
Also for projects with self-consumption, a new planning stage has been introduced under the heading "Define load profile". This provides not only a chart of average daily profiles, but also an editor for creating individual load profiles.
The new section "Planning of PV system monitoring" provides the possibility of integrating communication products hardware and software for system monitoring, system management and visualization of key system data in the PV system.
This new function also offers design options based on the specific requirements for PV system monitoring. The sizing of AC cabling now also supports split-phase grids.
Project documentation for design alternatives can now be created quickly and easily. The dialog for creating your own PV modules has been optimized. All mandatory specifications have been condensed in one list to facilitate their entry. Missing PV module data can now be transmitted by e-mail via a link on the homepage.
The user interface and the documentation are now also available in Japanese. The new version has been prepared for inverters with integrated battery. Thanks for this great tool! Are there string sizing tools available for inverters larger than the TL?
I am installing SMA us, and need the proper dc string voltage, for proper operation. I have dcv, on one string, and about vdc on second string. Could you help as I find these string sizing programs offered by all manufacturers to be very helpful to save lots of design time.
Do you see any issues here? I am a newbie and still learning about solar. Question about which inverter to use. I get all green checks for both systems when inputting all the data. I am reading about the DC to AC ratio which should be around 1.
