RatedPower updates pvDesign software program to align with NEC and IEEE requirements
RatedPower has improved the way the NEC is implemented in its pvDesign software for cable sizing, introduced IEEE standards for connector size, and now offers all downloadable documentation in Imperial Units.
Over the past few months, the RatedPower engineering team has been working hard to improve the implementation of the NEC when planning solar PV projects with pvDesign. The main improvements include:
- The amperage tables for cables have been updated
- The NEC isolations were included
- The soil temperature, thermal resistance and trench depth correction factors have been added
- The dimensioning of the cables with regard to the voltage drop has been changed and improved
With regard to the implementation of the IEEE standard, pvDesign users can now have their substation (electrical devices, insulation coordination, short circuit calculations and busbar calculation) dimensioned according to this standard.
The US customers of RatedPower have made it clear that it is important to download the documentation provided by pvDesign with Imperial Units. In order to adapt to the needs of the customers, the entire documentation in pvDesign can now be downloaded not only in the interface in Imperial Units but also in Imperial Units.
Meteo Data Importer
Last but not least, after understanding that SolarAnywhere and NREL are the most widely used TMYs in the US, RatedPower has integrated a meteo data importer that allows users to upload SolarAnywhere, NREL, Meteonorm or SolarGIS TMYs directly.
RatedPower will continue to customize pvDesign not just for the US market, but for all markets it is present in, trying to meet its custom requirements while remaining a global tool.
