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

Calculation with different number of panels on the string.
Lazare Fesnien replied to Bakhtiyar's topic in How-to
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 ?

Insert new models of batteries, and pv components in general
Lazare Fesnien replied to Leonidas's topic in How-to
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"

OND File for P700 Solar Edge Optimizer Missing in PvSyst Library
Lazare Fesnien replied to Tobi's topic in PV Components
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,
