Nominal DC voltage
The rated voltage on the input side for normal operation of the inverter.
Max. input voltage, Max. Input current
This voltage limit or current limit must not be exceeded to protect the inverter.
In PV*SOL® these limits are required for the configuration check, see Pages > Inverters > Configuration check.
Number of DC inputs
Electrical data AC
Nominal AC power
The nominal AC power is the power for which the inverter is designed on the output side for continuous operation.
Max. AC power
Exceeding these power limits results in power regulation of the PV output.
In PV*SOL® these limits are also required for the configuration check, see Pages > Inverters > Configuration check.

Changing the efficiency in case of deviation of the input voltage from the nominal voltage
The efficiency characteristic of the inverter is specified for the nominal voltage.
If an inverter is not operated at nominal voltage, the efficiency of the inverter changes.
The efficiency of an inverter decreases by the specified value per 100 V with deviation of the input voltage.
Minimum power that the inverter can feed into the grid.
If the inverter does not supply energy to the grid or to the consumer, the inverter’s own consumption must be taken into account.
Besides the stand-by consumption there is also the night consumption.
The inverter switches off at night, but still requires a minimum of energy.
Here you define the MPP-Tracker of the inverter.
MPP adaptation efficiencies
Power ranges < 20% of rated power
Power ranges > 20% of rated power
Interconnection of MPP trackers possible/not possible
MPP trackers cannot be interconnected
Either none or all MPP trackers are interconnected
Number of MPP trackers
Data per MPP tracker:
Max. Input current per MPP tracker
Max. Input power per MPP tracker
Min. MPP voltage , Max. MPP voltage
The MPP tracking of the inverter takes place within this voltage range.
To define the efficiency, specify the corresponding efficiency for all load ranges.
