Power limitation (Power Derating)
Скачано с сайта интернет магазина https://axiomplus.com.ua/
In order to allow inverter operation in safe thermal and electrical conditions, the unit automatically reduces the value of the power fed into the
grid.
Power limiting may occur due to:
• Adverse environmental conditions (thermal derating)
• Percentage of output power (value set by the user)
• Grid voltage over frequency (mode set by user)
• Grid overvoltage U>10min Der. (enabling carried out by user)
• Anti-islanding
• High input voltage values
• High input current values.
Power reduction due to environmental conditions
The power reduction value and the inverter temperature at which it occurs depend on the ambient temperature and on many operating parameters. Example: input voltage, grid voltage and power available from
the photovoltaic eld.
The inverter can therefore reduce the power during certain periods of the
day according to the value of these parameters.
In any case, the inverter guarantees the maximum output power even at
high temperatures, provided the sun is not shining directly on it.

Characteristics of a photovoltaic generator
Скачано с сайта интернет магазина https://axiomplus.com.ua/
A PV generator consists of an assembly of photovoltaic modules that
transform solar radiation into DC electrical energy and can be made up
of:
Strings: number (X) of PV modules connected in series
Array: group of X strings connected in parallel
Strings and Arrays
The string technology was developed to signicantly reduce the installation costs of a photovoltaic system, mainly associated to wiring on the
DC side of the inverter and subsequent distribution on the AC side. A
photovoltaic panel consists of many photovoltaic cells mounted on the
same support.
• A string consists of a certain number of panels connected in series.
• An array consists of two or more strings connected in parallel.
Large photovoltaic systems can include multiple arrays connected to one
or more inverters.
The greater the number of panels in each string, the lower the cost and
the less complex the wiring connections of the system.
CELL
The current of each array must fall within the limits of the inverter.

Description of the equipment
Скачано с сайта интернет магазина https://axiomplus.com.ua/
This equipment is a string inverter which converts the direct current of a
photovoltaic generator into alternating current and feeds it into the public
distribution grid.
Photovoltaic panels convert solar radiation into “DC” electrical energy
(via a photovoltaic eld, also called PV generator); in order to use it, it
is transformed into “AC” alternating current. This conversion, known as
inversion from DC to AC, is done in an efcient way by the ABB inverters, without using any rotary elements, rather only via static electronic
systems.
In order to allow inverter operation in safe thermal and electrical conditions, the unit automatically reduces the value of the power fed into the
grid under adverse environmental conditions or unsuitable input voltage
values.
When connected in parallel with the grid, the alternating current from the
inverter ows directly into the domestic or industrial distribution circuit,
which is in turn connected to the public distribution grid.
This way the solar energy system compensates for the energy drawn
from the utilities connected to the grid to which it is linked.
When the photovoltaic system is not generating sufcient energy, the
power required to ensure proper operation of connected loads is taken
from the public distribution grid. While if too much energy is produced, it
is directly fed to the grid, thus becoming available to other users.
According to national and local standards and regulations the produced
energy can be sold to the grid or credited to the user against future consumption, thus granting a great saving of money.

Mutual connection of multiple inverters
Скачано с сайта интернет магазина https://axiomplus.com.ua/
If the photovoltaic system exceeds the capacity of a single inverter, it is
possible to connect multiple inverters to the system, each of them in turn
connected on the DC side to an appropriate section of the photovoltaic
generator, and on the AC side to the distribution grid.
Each string inverter will work independently of the others and its own
photovoltaic module will supply the maximum power available to the grid.
Notes on the system sizing
Decisions on how to structure a photovoltaic system depend on a series of factors and considerations, such as the type of panels, the space availability, the future location of the system, energy production goals over the long term, etc.
A conguration program that can help to correctly size the photovoltaic
system is available on the ABB website (http://stringsizer.abb.com).
