Electrical data

Inverter: Electrical data

Here you define the electrical data of the inverter.

  • Nominal DC power
    The nominal DC power is the power for which the inverter is designed on the input side for continuous operation.

  • Nominal AC power
    The nominal AC power is the power for which the inverter is designed on the output side for continuous operation.

  • Standby consumption
    If the inverter does not supply energy to the grid or to the consumer, the inverter’s own consumption must be taken into account. In addition to standby consumption, there is also night consumption.

  • Night consumption
    The inverter switches off at night, but still requires a minimum of energy.

  • 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.

  • Nominal DC voltage
    The rated voltage on the input side for normal operation of the inverter.

  • Mains connection

    • 1 phase
    • split-phase
    • 3 phase
  • Max. DC power , Max. AC power
    Exceeding these power limits results in control of the PV output. In PV*SOL® these limits are also required for the configuration check, see Pages > Inverters > Configuration check.

  • Feed in from
    Minimum power that the inverter can feed into the grid.

  • Number of DC inputs
  • Galvanic isolation of the inverter

    • With transformer
    • Without transformer
  • 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.


Inverter: MPP

Here you define the MPP-Tracker of the inverter.

  • MPP adaptation efficiencies

    • Power ranges < 20% of rated power
    • Power ranges > 20% of rated power
  • Parallel operation

    • 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.
