Using the solar industry’s most advanced residential inverter is now even easier, thanks to the new for the. Now available for free download, it provides string design and inverter sizing recommendations in a simple, easy-to-use format.
Just input basic module criteria found on data sheets a details like design temperature, loading ratio preferences and the AC output voltage. Based on this information, the Quick Design Reference Tool will calculate the optimum number of strings and modules per string, as well as the ideal inverter loading ratio (DC:AC) and model of Sunny Boy TL-US with Secure Power Supply. This customized assessment can be printed for customer presentations or as a reference during installation.
Download the free Quick Design Reference Tool from the Sunny Boy TL-US with Secure Power Supply and start designing! Quick question about this design tool. We have a 31 panel (SunPower 327) project coming up. Your tool doesn’t seem to address this number. I’m thinking of the 7700TL with 3 strings of 7 and 2 strings of 5.
Sma String Sizing Calculator
One tracker would have 2 strings of 7 in parallel with the a 3rd string of 7. The other tracker would have 2 strings of 5. The strings of 7 face east and the strings of 5 face south. Is there a way to determine the appropriateness of this type of design with the 7700TL given the different orientation factors and production considerations. Hi Daniel – You bring up an interesting point.
The QDR tool only goes up to (4) string inputs because the inverter only physically has 2 inputs per channel. For most modules you cannot connect more than two strings per one channel, this is why the tool will not recommend (3) strings on channel A and (2) strings on channel B. However, Sunpower modules have really low amperages and are the only exception. At this time is the best way to simulate the design.
Nevertheless, you can verify if (7) modules in series as well as (5) modules in series are compatible within the QDR tool and then manually verify that the combined ISC for (3) strings will not exceed 20A and check for proper DC to AC ratios. Also, if you decide to utilize the 3+2 approach – the (3) strings being connected to Channel A will have to be combined prior to connection (because the inverter only has 2 physical inputs) and fuses may be required. All the best, Justin.
With the latest release of the Sunny Design application, designing PV systems is even easier. Simply install Sunny Design on a Windows-operated PC or open the online version using a browser, iPad or Android tablet, enter all required data and receive the ideal plant configuration within minutes. The application provides solar power professionals and system planners with a user-friendly interface, which thanks to the new desktop version matches Sunny Design Web.
The software also delivers data for an economic evaluation of the system alongside the technical verification of the various components. The end customer gains a customized PV plant and the solar power professional saves valuable time. Release Notes Sunny Design 3.55 (Web/Desktop).
Improved handling of the active power limitation with Sunny Boy 1.5 to 5.0. 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. The specific requirements in the USA regarding UL 1741SA / Rule 21 can be factored in as country-specific requirements.
The information regarding the compatibility of PV inverters with AS-NZS 5033 has been improved. 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.
Database changes:. New PV inverter: SHP75-10. New locations: San Diego (CA, USA) and 'Eifel' region (Germany). Updated PV module database (now containing 123,017 PV modules and 1,348 manufacturers). Release Notes Sunny Design 3.51 (Web/Desktop). Sunny Design now allows to design PV systems containing TS4-R retrofit MLPE components (Module Level Power Electronics) by Tigo Energy. 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 monitoring systems: SMA Com Gateway, Tigo Gateway, Tigo Cloud Connect Advanced. New inverters: SB3.0/3.6/4.0/5.0-1AV-40, SC 1850-US-10. Updated PV module database, now also containing the connector type.
The new version also contains various minor improvements and bug fixes. Release Notes Sunny Design 3.50 (Web/Desktop). Full product support for Sunny Boy 5.0/ 6.0-1SP-US-40 (parallel connection of inputs).
Off-grid systems: integration of Sunny Island 4548/ 6048-US and the Multicluster Box 12U. 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. An alternative dimensioning factor (peak power / max. Inverter AC active power) is now available in the user settings. Designs with central inverters also comprise information about SMA system technology.
Updated consideration of the KfW subsidies for energy storage systems (50% cut). 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.g. At presentations).
Improved presentation of the power tolerance of PV modules. Download winzip for macbook pro free. Manual input of battery efficiency. Improved update dialogue regarding the Sunny Design desktop. Different minor improvements and corrections (bug fixes).
