Release Notes Sunny Design 3.10
- In Sunny Design there are now three different project types available which are individually tailored to specific requirements: PV system without self-consumption, PV system with self-consumption, and PV hybrid system. 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.g., for implementation of the 70% cap in accordance with the Renewable Energy Sources Act (EEG). 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 design now takes into account the requirements of country-specific standards in Belgium (RGIE), Australia (AS/NZS 5033) and Italy (CEI-021).
- 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. Their properties will in future be taken into account for design, yield simulation and self-consumption forecasting.
Changes in Version 2.30
- Central inverters with reactive power capability: The calculation of the minimum DC voltage dependent on the displacement power factor has been revised.
- When the line voltage changes, the minimum PV voltages are tested now.
- Improved consideration of DC currents with the yield forecast.
- New inverters: STP 5/6/7/8/9000TL, SC 500CP XT, SC 630CP XT, SC 800CP XT, SC 850CP XT, SC 900CP XT, SC 720CP XT, SC 760CP XT, SC 720CP XT (700 kVA / 315 V), SC 760CP XT (740 kVA / 333 V), SC 800CP XT (780 kVA / 351 V)
- Updated country approvals: SB 2100TL, SB 3000TL-21, SB 3600TL-21, SB 4000TL-21, SB 5000TL-21, SB 3/4/5000TL-20, SCxxxHE-11
- New product images of SB 1300TL-10, SB 1600TL-10, SB 2100TL
- New locations: Islamabad (Pakistan); Hanoi, Ho Chi Minh City (Vietnam)
Changes in Version 2.21
- When displaying project documentation there is also a page on self-consumption available now.
- PV arrays can now have up to 500,000 modules.
- If the number of strings on one input exceeds the number of inverter connections, information to this effect is displayed in the overview.
- A minimum of 4 mm2 is now recommended for DC cable cross-sections in the cable dimensioning section.
- Improved design recommendations through optimized ranking in the profitability evaluation process.
- If there is no maximum unbalanced load stored for a location, the "Consider max. unbalanced load" check box is no longer pre-selected.
- When testing for too-low string voltages, only a yellow warning is displayed now if the minimum PV voltage is lower than the minimum MPP voltage of the inverter at grid nominal voltage.
- The yield calculation has been improved for PV arrays with tilt tracking.
- A problem when accessing no longer existing network drives during Sunny Design start-up has been resolved.
- New inverters: SC 500CP-US, SC 630CP-US, SC 720CP-US, SC 750CP-US, SC 800CP-US, SC 500CP-JP
- New locations: Esbjerg, Odense (Denmark)
- Improved meteorological data is now used for certain locations. As a result of this the energy yield prognosis and the calculated optimum nominal power ratio can differ from the previous version.
