"Strongly Oversized" Warning in 12 MPPT Inverter

[elisdown]

Hi,

 

I am studying to build a PV system of 555W panel installation on three different levels of building. However the PVsyst warned "strongly oversized" of inverter.

G/F: 94 pcs of PV panel, is divided into 2 x 15 + 2 x 16 + 2 x 16

4/F: 70 pcs of PV panel, is divided into 2 x 17 + 2 x 18

R/F: 70 pcs of PV panel, is divided into 2 x 17 + 2 x 18

Inverter Model: SMA Tripower Core 2 is available with 12 independent MPPT (2 strings per MPPT) (https://files.sma.de/downloads/STP110-60-AFCI-DS-en-20.pdf)

PV Panel Model: 555W Seraphim (https://www.seraphim-energy.com/wp-content/uploads/download/SRP-(540-555)-BMA-HV_182_EN.pdf)

 

Is there any setting wrong I did?

The error message in red is normal. You have defined a PV power on your main input well below its nominal power (55 KWac). You need to increase the number of strings on this main input
