Update 1.22 Photosimpianti
It 'available in the download version 1.22 of the 2010 PhotosImpianti 29/12/2010
Log updates:
- Ability to change minimum and maximum temperatures for the calculation of PV modules paramettri electrical and verification coupled with Inverter
-Fixed bugs for typing coeff. PV Modules
-Possibility to progress calculations with values Pot of Max inverter side DC, (calculated at the minimum temperature and radiation of 1000W / m ^ 2), above all DC Inverter Max Pot.

Always Pmax DC?
After some clarification, and requests received by e-mail carry a small selection that I think may be helpful to latria:
Many manufacturers omit the data of the inverter DC side Potez Max.
This is because it is strongly recommended to size the PV system to MAX DC side, but should be back on the nominal size in order to have an operating margin in particular cases of solar radiation and / or sudden changes in temperature, protects 'inverter *. (* Inverter which only the manufacturer knows the true maximum operating margins).
This obviously respecting the conditions of voltage, current maximum and minimum 'inverter.
The Power Max DC side in 'inverter is usually given by:
Imax (DC) x VmpMax (DC) = Pmax KWp
This power is clearly THEORETICAL , because the manufacturer does not provide information on the Power Max DC real usually greater than the nominal but less than that calculated . It 'also true that most likely will not be able to establish such a power inverter input, as higher than the value of Imax, Voc, and VmpptMax VmpptMin inverter.
E 'possible to verify that fact by applying this formula on a number of inverters in circulation, the values \u200b\u200bof the DC power Max recommended are significantly lower than those calculated using the formula Imax (DC) x VmpMax (DC).
Photosimpianti 1121 sizing runs on Nominal and if it exceeds the value thereof, indicates the overhead calculations showing Inverter Output hour did not exceed the Max DC power (theoretical and / or real ).
It is up to you to verify the optimal operating parameters, so 'as to all other software is generic, as the software course could not provide the optimal configuration in all possible cases.
E 'should therefore always check the configuration information and software manufacturers themselves.

PhotosImpianti 2010 on Ubuntu Linux 1.21 Ubuntu
I have personally tested PhotosImpianti 2010 on the official version of Ubuntu 10.10 and I must say with great results.
Here are the steps: First you must
install Wine from the Software Center Ubuntu
Once installed go to terminal and type: wget
http://www.kegel.com/ Wine / winetricks
then
sh winetricks corefonts vcrun6 jet40 mdac25 MDAC28 vb6run
Run the normal setup of PhotosImpianti 2010 and installed the software that should work now so great stuff!

What To Write In A Sympathy Card For Cancer
The DC Power Max or Rated?
Given the confusion on this type of coupling modules and PV panels are trying to understand together.
I got to see several tools for coupling Inverter and sometimes with different results and / or conflicting.
Normally producers Inverter DC supply side, two powers:
Given that the total number of strings connected in parallel to the inverter must meet the following limits: The Voc
Modules -10 ° C lower than the Vmax Inverter
at OLV-70 ° C greater than the inverter VmpptMin
OLV -10 ° C less than the Inverter VmpptMax
Isc (total strings) less than the IDC Max Max Power Inverter
The strings = (pmode * * nMode nSTRING at -10 ° C) must be less than the Max DC Power Inverter ! Translated
would want to say find the coefficient. of Power / temperature module or at least the second coefficient. voltage and current, then calculate everything to the limit temperature (-10 ° C).
you might find in the special case where, after checking the voltages and currents, the power of these forms in terms of temperature limit far exceeds the maximum power inverter, resulting in the reality of the block because stesso.Ecco producers sometimes have a lot of difference between the nominal and maximum DC Pot.

Power Bug solved!
The software update is never facile.E 'available for download for those who find a bug on the total power of PV generator (not shown), the version of PhotosImpianti 2010 1:21 3/12/201 should definitely solve the problem. Please
anyone had installed earlier versions to upgrade to version 1.21
Thanks.
