how to determine ac collection panel?

[hamidkursad]

There is an AC collection panel at the pv system. However, I did not find the AC collection panel in the program. Could you help?

Hi Hamid,

Not sure that PVsyst can model an AC PV Module.

In practice, an AC module is just a standard module with a built-in micro-inverter.

The use of "AC modules" has indeed been implemented in PVsyst since several years.

For the association (PV-module - Micro-inverter), the remarks of the AC module should mention: "AC module (with LM305UE-G1 (240V) AC module of LG Electronics)"

and inversely the remarks of the inverter will mention "AC module (with LG 300 A1C-B3 ACModule 240V of LG Electronics)".

However only one device has been proposed by manufacturers up to now. This is the LG Electronics LG 300 A1C-B3 AC Module 240V (or --- 208V).

When choosing this device, the corresponding micro-inverter LG Electronics LM305UE-G1 (240 or 208V) is automatically selected.

In the sub-array, please make sure that you define the same number of inverters than the number of modules.
