No you can keep this box checked but instead of modifying the number of inverters you will have to modify the number of MPPT input in this case

To do this, you must create different sub-arrays. When you have a different number of strings on the MPPT inputs, you should create one sub-array for each configuration (for example one sub-array for the MPPTs with a single string, and another one for the MPPTs with two strings). Then, in ‘power sharing’, you tell PVsyst which sub-arrays belong to the same inverter and how the power of the inputs is balanced. I have attached a PDF document to this e-mail with short examples on how to proceed. You can also find more information in the help under: ‘Project design > Grid-connected system definition > Multi-MPPT inverters’ ‘Project design > Grid-connected system definition > Multi-MPPT inverters: power sharing’

Indeed in this case, as you need to maintain the DC/AC ratio of 1.20 you must manually modify the number of inverters in order to find the desired ratio

If you want to maintain the power of the PV field and the ratio of 1.20 then you must act on the number of inverters and the power of the inverters

Dear Paul Adrian, I think I didn't quite understand your question. I don't know if you want to maintain the same DC/AC ratio of 1.20 or maintain the PV power ?

No, but on the other hand you can put components in "favorites"

We update the database using the requests of the manufacturers, and publish it with each new release of PVsyst. We can't of course follow all the new products of all manufacturers in the world. We don't want to include data without the acknowledgement of the manufacturer. Nevertheless you can easily create your own components by yourself. The easiest way is to choose a similar existing device in the database, modify its parameters according to the manufacturer's datasheets, and save it under a new name, therefore creating a new file in your database. You have a tutorial for that on youtube: https://www.youtube.com/c/PVsystTutos, page Component database

To help you, please send us the PAN files to support@pvsyst.com

You should change the "available Now" and "Bifacial modules" filters to show all the components"

Dear Prayash, This should come from the PAN file you created. Please send it to us at support@pvsyst.com in order to find the problem.

Dear Tobi, The SolarEdge architecture follows very complex and strict rules specified by the folks at SolarEdge. PVsyst scrupulously applies these rules, they are irreversible. These rules define in particular the conditions of compatibility between optimizers and inverters. This implies that all components are specified in the internal PVsyst database. If an inverter is not referenced in the PVsyst database, it cannot be used. Please ask SolarEdge to update their products in PVsyst. Regards,

Dear Hritik, Where does the PAN file come from? Does it come directly from the manufacturer? There may have been a modification of the technical sheet between the creation of the PAN file and the marketing of the component. You can update the component yourself if you notice any differences. For the temperature coefficient you can choose to define it in mA/°C or by %/°C, PVsyst will automatically calculate the other value. Regards,

Your inverter is not defined as allowing work with a cos phi. To resolve this you must modify the OND file from the database
