MPPT current value in the report

[Ajay Deepak]

Hi,

In most cases, PVSYST calculates the MPPT current based on the voltage automatically. Could you please mention the MPPT current considered by PVSYST for calculation in the report? At present only MPPT voltage ranges are mentioned.

This doesn't make much sense.

The voltage mentioned here is a limit for operating conditions.

The current is roughly proportional to the irradiance. The input current limit has not a "universal" definition, especially at the array level. It is not always well defined in the OND files.

As the maximum input current is not mandated in the OND, I always find it empty in the database. In this case, how PVSYST will know the current limit? 

For example in the help section "string inverters, current limiting", it mentioned that 15A is the current limit considered. If the data is not filled, then how will PVSYST calculate this value?

Mentioning this current value will very help full in better clarification. And for the definition, we can refer to IEC 62894.

Hi,

Can we consider this as the PVSYST limitation for now?

Ajay.
