INSTALLATION
BEFORE INSTALLATION
!
!
Grid Interactive Solar Systems have become increasingly popular in recent
years. These systems do not necessarily require batteries for storage and
therefore can have a very simple configuration.
Ensure the Inverter has not been damaged in transit.
The unit must be placed in a well ventilated and protected area, not exposed
to the open environment, and free from contaminates (i.e. exhaust gases,
sea air, dust etc.).
The PV edge is designed for indoor installation in a suitable location where
ambient temperature will not exceed rated values.
As the PV edge has a wall mountable enclosure, ensure proper air circulation
for cooling of the Inverter.
Safety- DC solar input and AC grid are electrically and galvanically isolated
via the Toroidal Transformer.
It is important that all wiring in the installation complies with the relevant
standards (AS4777) .

DC WIRING
Check solar array does not exceed inverter’s maximum voltage rating!
If other sources of DC input are required e.g wind turbines, micro hydro
turbines etc, a battery bank or Latronics Turbine Controller (see pg 9) will
be required with the Maximum Power Point Tracking (MPPT) disabled
(see pg 13).
The DC input voltage is stated on the PV Edge compliance label and the
technical specifications sheet within this manual. Check that the input
voltage is within the required limits and does not exceed the maximum
limit (see pg 18).
Recommended cable size for the DC Input is 6sqmm with an insulation
rating of 0.6/1KV.
The Inverter is fitted with DC circuit breakers for the positive and
negative DC Input connections.
Ensure the DC breakers are switched OFF when connecting or
disconnecting the DC leads.
The PV Edge inverter is suitable for use with solar arrays that require positive
or negative earthing. Due to the inverter’s galvanic isolation between AC and
DC inputs no additional modifications are required. Simply connect the
positive or negative of the solar array to the system earth.
Observe Polarity.
* The inverter is designed to operate with a 48V solar panel array
(PVE1200) or 96V solar panel array (PVE2500).
* A 48V solar array will have an open circuit panel voltage of about 87Vdc.
* A 96V solar array will have an open circuit panel voltage of about 174Vdc.

AC WIRING
Both models require an external 10A circuit breaker for protection of
inverter’s AC input. Usually mounted in main switchboard. The active and
neutral of the AC output are electrically isolated from the DC inputs and earth
connections.
Latronics Inverters have the AC output (active and neutral) floating with
respect to the DC and Earth. This configuration provides the highest safety
and most flexibility for installation wiring. The earth is connected internally
to the Inverter case and is suitable for wiring.
The unit is supplied with both male and female 20Amp Wieland Gesis
lockable AC connectors that
To install connectors read the following procedure.
1. Make sure Inverter is switched OFF before working on mains wiring. Turn
external AC Circuit Breaker switch into OFF position and
make sure it cannot be switched back on.
2. Test the wiring with a voltmeter to make sure no voltage is present.
3. Peel back 30mm of cable jacket and cut Active and Neutral cables
5mm shorter than Earth.
4. Strip 5mm off all three cables.
5. Take the Wieland Gesis connector, disassemble into three main sections
and insert stripped wire through as shown below.

RADIO FREQUENCY INTERFERENCE
Radio Frequency Interference (RFI) is a phenomenon that exists in modern
society and is a problem in many areas of electronics. For Inverter users,
RFI normally presents itself in the form of static and/or interference when
listening to an AM radio and in unusual cases may interfere with TV reception.
Over the years Latronics has continued to invest significant time and effort in
the reduction of RFI related emissions from the entire product range, so that
they comply with the appropriate International and/or Australian Standards.
Even with this compliance, there are situations where RFI may still be a cause
for concern, and can differ greatly from installation to installation. Accordingly,
the following is a list of recommendations made to assist in the overall
reduction of RFI.
1. Avoid running DC and AC cables in the
same conduits and/or cable trenches. It is strongly recommended that
DC and AC wiring be separated by the greatest distance possible. In
extreme cases, the use of shielded conduit may be necessary.
2. . DC cables can act as an aerial,
therefore all such cables should be kept as short as is practicable. For
best performance minimize DC cable length to Inverter and Batteries and
if possible avoid the use of auxiliary DC loads.
3. . For household installations, it is recommended that a
“good” Earth Stake is located as nearby the Inverter as is possible.
4. These types of radio equipment inherently suffer
from all forms of RFI, especially when the received signal level is weak.
In such cases reception can sometimes be improved by relocation of the
radio itself, alternatively the use of an appropriate external antenna and
co-axial cable may be necessary. External antennas should be located
in a manner that ensures maximum signal strength whilst affording the
greatest possible distance away from the Inverter and Batteries.
5. TV signals are transmitted as FM waveforms. This type of
signal fundamentally reduces the effects of RFI, therefore the use of a
good antenna and feeder cable is normally sufficient to ensure quality
reception. Locating the television as far as possible from the Inverter may
also improve picture clarity.
Separate DC and AC wiring.

6. Connect the Active, Neutral and Earth cables as per diagram below.
7. Push the socket back into the Main Body until it clips in.
8. Screw the Pressure Ring back in to form a tight seal.
9. Plug into PV Edge.
To disconnect the plug, simply push the clip in and unplug.

FAULT FINDING
HELPFUL HINTS
Should the Inverter appear to be malfunctioning we suggest the following to
eliminate any external problems.
Turn the Inverter OFF by switching the DC & external AC Circuit
Breakers OFF. Leave OFF for 60 seconds.
Reconnect the DC Solar Input by switching DC breaker ON. All lights
on the Inverter should come ON for 1 second at power up and then go
OFF. The 75% light should remain ON to indicate the Solar Input is
available. Solar Input voltage needs to be above the automatic turn ON
voltage, see pg 18, for the light to turn ON. If the light does not
illuminate check Solar Input for correct operation.
Next reconnect the AC grid by switching the external AC breaker ON.
After 20 seconds the 75% light should begin flashing to indicate Inverter
reconnecting to the AC grid. The light will flash for 60 seconds while the
PV Edge checks that the mains voltage and frequency are stable.
Should the light not begin flashing check if the AC grid is present.
After the 75% light stops flashing the Inverter will begin feeding power
into the AC Grid.

SPECIAL FEATURES
Circuit Breakers
Digital KwH Meter
Night Time Disconnect
Parallel Operation
Note:
Maximum Power Point Tracking
Protection
Maintenance Cycle
There is one double pole DC circuit breaker isolating both DC positive & DC
negative.
The KwH meter shows an accumulative reading of the total power generated
and allows the user to monitor their green power production. LCD display
with 5 digits and 2 decimal places (i.e. 99999.99kwh).
After dark when the solar input is no longer available the Inverter will
automatically disconnect from the AC grid. This feature ensures that during
the night, the Inverter cannot consume any power whatsoever while
remaining idle. Upon sunrise the next morning when solar input becomes
available again, the PV edge will automatically reconnect to the AC grid and
begin generating power.
The PV edge automatically synchronizes to the AC grid, therefore the output
of multiple units can all be connected together, and they will all be
synchronized by the AC grid.
The optimum power level from the solar input depends on the available solar
modules. Even in cloudy weather with fluctuations in the solar radiation
level, the PV Edge constantly monitors and tracks the optimum operating
point to ensure maximum power from the solar modules is achieved.
The AC grid supply is constantly monitored for under and over voltage, over
and under frequency, and anti islanding conditions via active phase shifts.
The DC input is protected against over voltage, reverse polarity and over
current via very fast current limit control. Isolation between the DC input and
AC output is achieved via the Toroidal Transformer. The temperature of the
transformer and switching devices are continuously monitored. The Inverter
is fitted with a cooling fan, which is temperature controlled and only operates
when required.
When in Battery mode ( MPPT disabled) a maintenance cycle is performed
every 30 days. This is a short boost cycle for sealed batteries or an equalize
charge for flooded cells. In this mode the bottom LED will flash slowly until
the cycle is completed.
The Solar inputs of multiple unit Inverters are not to be paralleled.
