4 Adjust the maximum DC/AC sizing. This is the ratio between the

rated STC power of the modules and the inverter peak AC power.

Adjusting this range allows you to change the inverter over-sizing.

Save a maximum sizing value with the Set as Default icon. You can

choose your default value by pressing the Restore Default icon, and

you can return to the SolarEdge maximum value by pressing the

Restore SolarEdge Default icon.

5 Germany only: If the system size is <30kWp, this checkbox appears.

This allows you to get designs with an AC/DC ratio according to EEG

2012. When this box is checked the inverter AC power can be limited

to a value between 60-70% of inverter max AC power.

6 If you change any of these settings, press Recommend again.

Each recommended design includes the information detailed below and

shown in Figure 10.

Figure 10 – Recommendation

1 Recommendation #. In the example, recommendation 1 is shown.

2 Inverter models and quantity. In the example, there are 3 inverters from

one model and 1 inverter from a second model. Rge 3 inverters from

the same model are split into two groups (inverters 1-2 and inverter 3)

because the inverters in the first group have different string sizing from

the inverters in the second group.

3 Number of strings per inverter, and power optimizer quantity and

configuration from each array, per string. In the example, each inverter

from the first group has 2 strings, each with 26 OP250-LV power

optimizers from array “South”, the inverter from the second group has

2 strings, one with 26 OP250-LV power optimizers from array “South”

and the other with 25 OP250-LV power optimizers from the same

array, and the inverter in the third group has 1 string with 35 OP250-

LV power optimizers from the array “East”.
