GLOSSARY of Terms & Abbreviations
This manual uses the following terms and abbreviations:
Term/ Abbreviation Explanation
AUX Power Supply
This refers to a secondary or backup supply that can be connected to the ECODRIVE during
times of Low solar intensity or no sunlight.
Blocking Diode
This is a semiconductor device that is connected in each string that allows current to flow in
one direction only. It prevents current flow from the ECODRIVE to the PV modules.
ECODRIVE
This is a ZENER product that converts a DC supply (and AUX AC supply) to control a 3phase
induction motor dependent upon the power extracted from an array of solar panels. A
registered trademark of Zener Electric Pty Ltd.
Grid Interactive Inverter
Is a device that converts direct current (DC) electricity into alternating current (AC) with an
ability to synchronize and be fed onto the public utility grid.
kW
Kilowatts.
A measurement of power, that can refer to electrical or mechanical power.
MPPT
Maximum Power Point Tracking
. The control or algorithm to extract the maximum available
power from the PV array under all conditions.
NOCT
Normal Operating Cell Temperature
. Measurements are provided by PV manufacturers to
provide a more practical/in field ratings. Defined as the temperature reached by open
circuited cells in a module under the conditions as listed below:
Irradiance on cell surface = 800 W/m
2
Air Temperature = 20°C
Wind Velocity = 1 m/s
Mounting = open back side.
PID A type of automatic controller that seeks to drive a measured value (such as pressure) to a
preset value by means of a control effort determined by proportional, integral and derivative
functions.
Photovoltaic cell / PV
This refers to the device used to convert sunlight directly into electricity by the photovoltaic
effect. The output is a DC voltage.
PV Array or Solar Array
This is a network of solar panels connected in a ‘series & parallel’ arrangement to achieve
the required voltage and current (Power)
PV String
This refers to the series connected PV modules. The number of PV modules in a string will
determine the system voltage. The strings of equal quantity of modules are then connected
in parallel to achieve the current & power required.
STC
Standard Test Conditions.
Stands for standard test conditions and is the major solar panel
output performance testing condition used by most manufacturing and testing bodies. The
test conditions are defined as – irradiation: 1000W/m
2
, temperature: 25°C, AM:1.5
Vmax.
Voltage at maximum power
. Voltage measured at output of a Photovoltaic module or array,
with a load connected under maximum power conditions.
Voc
Open circuit voltage
. Voltage from the Photovoltaic module or array without no load
connected.
