Static power limitation of inverters

[Loïs Masson]

Hello,

 

In France, low-voltage grid connections are only available for photovoltaic plants with an apparent power of up to 250 kVA.

However, in some cases, we need to to use several inverters, resulting in a total installed power higher than 250kVA. 

In this situation, inverters are subject to a static power limitation of 250 kVA to comply with low-voltage grid connection constraints. 

What's the best way to simulate this limitation in PVSYST ?

Should I simply define a grid power limitation ?

or should I change the maximum power output of my inverters in the .ond files ?

I have tested both approaches but the results are not the same 

I would appreciate your insights on the most accurate way to model this scenario.

 

Best regards

Hello,

Indeed if it is a grid limitation can be applied in the Energy management window, Grid power limitation, instead of modify the inverter. 

If the grid limit is in apparent power, note that you here can change the limit from active power to apparent power.

Kind regards
