13.2.3 Inverter – Grid Connected Systems
The characteristics for the inverter are entered in this window. Details on using the
database are given under Project Design.
If you want to enter an inverter that can be switched to different voltage levels, you will
have to enter the individual voltage fields as separate inverters with the characteristic
data for each of these.
As in all database dialogs there are the Load, Save and Close buttons and there is also a
Print button.
Manufacturer and Type are allowed a maximum text length of 50 characters.
DC Power Rating [kW]
DC stands for direct current and refers to the input side of the inverter. As this value is not
clearly defined by inverter manufacturers, it is no longer used in PV*SOL and is shown for
information only.
Max. DC Power [kW]
This value is also not clearly defined by inverter manufacturers. It is no longer used in
PV*SOL and is shown for information only.
AC Power Rating [kW]
AC stands for alternating current and refers to the output side of the inverter. The AC power
rating is the output that the inverter is designed for when in continuous operation. When
the inverter is in continuous operation the power output is limited, with the AC power
rating being the upper limit.
Max. AC Power [kW]
The output that the inverter can produce in 10 minutes. This value is not currently used in
PV*SOL.
Stand-by Consumption [W]
If no energy is being delivered into the grid or to the electrical appliances, the energy
required by the inverter itself still has to be accounted for. In addition to the stand-by
consumption there is also night consumption.
Night Consumption [W]
The inverter switches itself off during the night, but still uses a small amount of energy.
Input Level [W]
The minimum amount of energy to be produced by the PV generator before the inverter can
function.
Nominal DC Voltage[V] / Nominal DC Current [A]
