1.3. Features
The EEdS is an advanced four-quadrant, three-phase, 4 wire 30 kVA inverter which uses the latest Silicone Carbide
and polypropylene capacitor technology to give an expected life of 20 years. The EEdS inverter has the following
features:
True three-phase 400VAC 30kVA inverter in one package;
Can be operated as a three-phase four-wire @30kVA or single two-wire @20kVA;
Frequency 50 or 60Hz;
DC input range 600 - 1000VDC;
Full four-quadrant - capable of sourcing/sinking VARs and import/exporting kW to full rating;
Four wire three-phase with individual phase current balancing;
Battery charging and discharging of energy storage devices;
Power conditioning compensation for grid sag/swell and voltage fluctuations;
Programmable harmonic sink;
Selectable current source or voltage source inverter;
Power factor correction;
Power flow regulation;
Uninterruptable Power Supply (UPS) function;
Off grid operation;
Communication Interface - TCP/IP or WIFI;
Communication Protocol –Modbus;
Data logging for one year.
1.3.1. Three-phase or single-phase
Two versions of the EEdS are available. A three-phase four wire @ 30kVA unit or as a single-phase two wire 240VAC
@ 20kVA unit. The EEdS is factory configured for each of these configurations. Both units are transformer-less
operation.
1.3.2. DC voltage range
The DC voltage range of the EEdS is 600 - 1000VDC. For three-phase operation the DC voltage range is typically 680-
980VDC depending on the AC output voltage required.
1.3.3. Frequency
Frequency can be configured for either 50Hz or 60Hz.

Commercial-In-Confidence Page 10 of 58 © eleXsys R&D Pty Ltd Apr 2020
1.3.4. Four quadrant operation
The EEdS is capable of
1. Import real power up to 30kW;
2. Export real power up to 30kW;
3. Generate VARs up to 30kVAR (capacitive);
4. Sink VARs up to 30kVAR (inductive).
1.3.5. Phase balancing
The EEdS is essentially a four-phase device with the neutral being modulated to measure and remove any negative
phase sequence components resulting in a balanced three-phase current output. For an unbalance situation, phase
currents can be balanced by generating currents between phases to balance the phase currents. Phase balancing is
optional.
1.3.6. Battery charging and discharging
The EEdS is capable of discharging a connect battery up to its full rating of 30kVA at any power factor between zero
and one. It has built in constant current/ constant voltage algorithm for charging various lithium batteries. The
charging current, charging voltage and cut off voltage can be set for different battery chemistries.
1.3.7. Power conditioning
The EEdS can be used as a power conditioner to improve the quality of supply. It is capable of regulating the phase
voltages to particular voltage and bandwidth. The voltage and hysteresis bandwidth are user settable. Sags and
swells will be corrected by first sourcing or sinking VARs to the correct voltage exertion and, if a battery is present,
will correct the voltage by generating or consuming real power. Sag and swell thresholds (voltage and time) for
correction are also user settable.
1.3.8. Harmonic correction
The EEdS is capable of sinking selected harmonics to improve total harmonic distortion of voltage supply. The unit
can be programmed to present a low impedance to neutral for programmed frequencies.
1.3.9. Current or voltage source inverter
The EEdS can be programmed as either a voltage source EEdS for off grid applications or a current source EEdS for
on grid applications.
1.3.10. Power factor correction
The EEdS can be used as a continuously dynamic power factor correction device to maintain unity power factor for
an installation. The generation of VARs for power factor correction is continuous not stepped as in standard power
factor correct products that use capacitors.

Commercial-In-Confidence Page 11 of 58 © eleXsys R&D Pty Ltd Apr 2020
1.3.11. Power flow regulation
The EEdS can be used to regulate power supplied to a connected load (i.e. demand limiting).
1.3.12. Uninterruptable Power Supply (UPS) –future development
EleXsys may be utilised as a line interactive uninterruptable power supply (UPS). For example, if the main grid supply
is lost, the eleXsys EEdS with a battery bank will maintain supply to the connected load by changing its operation
from current mode to voltage mode within one 50 Hz cycle, and provide kW and kVARs to all loads.
1.3.13. Off grid operation –future development
The EEdS may be used for off grid applications usually in conjunction with a battery and configured as a voltage
source inverter.
1.3.14. Grid Voltage Regulation
The EEdS can be used to regulate the voltage at a customer’s connection to the grid. By either sourcing or sinking
VARs, the voltage at the point of common coupling can be controlled to a specified voltage range. In this mode, the
EEdS can be used to limit voltage rise for DER generation and for improving voltage drop under high load conditions.

Commercial-In-Confidence Page 12 of 58 © eleXsys R&D Pty Ltd Apr 2020
1.4. Communication and Data Logging
The EEdS consists of two RJ45 connection ports for software communication, DRED control and data logging
functionality. The USB port is used for hardware developing purpose, and it will not be provided in the
commercialized version. WIFI communication functionality is pending upon the next stage hardware development.

2.2. Pre-cautions
2.2.1. Potential Hazards or Injuries
Electric Shock
The human body responds in several ways to electrical current flowing through it. The sensation of shock is
only one such effect and this can be extremely painful. When a shock is received, the electric current may take
multiple paths through the body and its intensity at any one point is difficult or impossible to predict. The
passage of the electric current may cause muscular contractions, respiratory failure, and fibrillation of the
heart, cardiac arrest or injury from internal burns. Any of these can be fatal.
Electrical Burns
Electric burns are due to the heating effect caused by the passage of an electrical current through body tissues.
They are most commonly associated with an electrical shock and often occur in and on the skin layers at the
point of contact with the electrical conductors which give rise to the electric shock.
Fires of an Electrical Origin
Electric Fires are caused by the heating effect of conductors passing current either intentionally or through
fault conditions such as when fault current flows, poor connections resulting in heat generation and possibly
Thermal ‘Run away’. Likewise, fires may result from arcing or explosions; igniting local fuel sources.
Electric Arcing
Arcing may result from intended or unintentional operations or activities. Arcing may result when an electrical
fault between live conductors or between live conductors and earth develops, when switching operations break
a high current circuit or when overcurrent devices attempt to clear a fault current. Arcing occurs when the air
acting as an insulator becomes ionised and becomes an electrically conducting agent, thus allowing current
flow to continue.
Explosion of Electrical Origin
Where as a result of any of the conditions detailed above caused local mediums to explode, or where the
electrical system explodes due to fault current or arcing.
2.2.2. Risks and Safety
Use of accessories not recommended or sold by eleXsys Energy Pty Ltd may result in a risk of fire, electric
shock or injury to person;
The EEdS is designed to be connected permanently to your AC or DC electrical systems. All wiring should be
installed by a licenced electrician or qualified technician. This will ensure the installation is adhering to the
local and the national electrical standards applied in your application;
Do not operate the EEdS with damaged or substandard wiring to avoid a risk of fire and electrical shocks;
Charge only with the rechargeable type batteries. The EEdS needs to be configured prior the use of new
installed batteries;
Do not operate the EEdS if it has received a sharp blow, been dropped or otherwise damaged in any way.

Commercial-In-Confidence Page 18 of 58 © eleXsys R&D Pty Ltd Apr 2020
Do not self-service or disassemble the EEdS. This should only be conducted by authorised and qualified
technician or electrician;
Do not expose the EEdS to extreme weather conditions. The EEdS shall not be used as an outdoor device and
a cabinet with an IP rating greater than IP55 is required;
Before any maintenance work is carried out, all sources of AC and DC power should be disconnected. Also,
10 minutes wait time should be given after the disconnection before conducting any further action. The
internal capacitor requires at least three minutes to be fully discharged depending on the voltage level;
The EEdS enclosure shall be connected to the MEN system with a 6mm2earth wire.
2.2.3. Working with Batteries
The EEdS has a DC rating of 1000VDC. All DC wiring shall a voltage rating greater than 1000VDC. All fuses,
circuit breakers, bus bars, terminals and connectors shall have a rating of at least 1000VDC;
Any DC equipment connected to the battery shall have a fault rating greater than the prospective fault rating
of the battery;
Any battery connected to the EEdS shall not be earthed;
Once the connection between battery and EEdS is made, the battery types, size, preferred operating
characteristics should be configured in the EEdS firmware;
If high voltage battery bank is connected, the area should be restricted to people whom has the authority or
knowledge about high voltage applications;
A dry chemical type extinguisher should be nearby in case of any fire accident.
2.2.4. Labelling of Electrical Apparatus
All operable electrical apparatus, underground cables, power transformers and voltage regulators should be
clearly and permanently labelled with a unique identifier except:
High voltage dropout fuses protecting a labelled pole mounted transformer substation or a labelled ground
mounted transformer substation with the fuse pole immediately adjacent to it; or OPERATIONAL
PROCEDURE –Electrical Safety Rules
Switch gear associated with labelled recloser, regulator and sectionaliser sites which are mounted on
common structures; or
Low voltage fuses or links associated with and on the same structure as a labelled pole mounted or ground
mounted transformer substation; or
Any other clearly identified operational apparatus such as low voltage service fuses, temporary mid span
high voltage live line links and live line clamps.
WARNING!
Do not connect or disconnect the battery while the EEdS is operating. Disconnecting the DC
leads while the battery is operating will result in severe arcing and injury to personnel.

Danger Tagging
“Danger - do not operate”tags must be attached to the controls of operable electrical apparatus to warn persons
against inadvertent or unauthorised operation (that would endanger the safety of persons or the reliability and
quality of supply) unless attachment to the controls is impractical in which case danger tags must be attached in the
next best locations to effect the warning.
“Danger - do not operate”tags must only be installed, altered or removed by authorised persons.
“Danger - do not operate”tags must also be fitted to unserviceable equipment to warn against inadvertent
energisation.
Persons shall not remove or alter in any way any tags that have been applied, without consulting the Network
Operator or person who attached the tag.
WARNING!
When an alteration occurs to electrical apparatus requiring labelling, the labelling must be
immediately altered to reflect the changed arrangement and system diagrams must also be
updated concurrently.
