9.1. How to Select and Configure PV Panels
The following parameters can be found in each PV panel’s specification:
• P
max
: Max output power (W)
• V
oc
: open-circuit voltage (V)
• I
sc
: short-circuit current (A)
• V
mp
: max power voltage (V)
• I
mp
: max power current (A)
PV panels can be connected in series or parallel in order to obtain the desired output voltage and
current which meets the inverter’s allowed range.
When connecting PV panels in
series, the max voltage and current of the string is:
