The principle of power optimization is to operate the module with its optimum current and at the same time to the inverter side for an identical current of all power optimizers within the string and an identical voltage of all parallel strings. To achieve this, either the output current can be increased (Optimizer mode buck or at module string level SubstringBuck) or either the output current can be increased or the output voltage increased (Optimizer mode full or at module string level SubstrinFull).
Max. output voltage
The maximum possible output voltage is important for the design of the inverter. If the max. possible output voltage corresponds to the no-load voltage of the PV module used, a -1 is entered here.
Some power optimizers, e.g. TIGO in “long strings” mode, limit the maximum output voltage to a value slightly above the MPP voltage of the PV module used in the STC. In this case, the voltage limit is entered here in Volt.
Max. output current
The maximum possible output current is important for the design of the inverter. If the max. possible output current corresponds to the short-circuit current of the PV module used, a -1 is entered here.
Min. MPP voltage
Max. MPP voltage
The MPP tracking of the performance optimizer takes place within this voltage range. This can be one or more connected PV modules or, in the Optimizer mode Substring, a sub-strand of the module.
Reduction of the open circuit voltage
This information is used for the configuration check (see Pages > Inverters > Configuration check).
To define the efficiency, specify the corresponding efficiency for all load ranges.
