Do not remove the casing. Inverter contains no user serviceable
parts. Refer servicing to qualified service personal. All wiring and
electrical installation should be conducted by a qualified service
personnel and must meet national requirements of AS/NZS 3000.
Both AC and DC voltage sources are terminated inside the PV
Inverter. Please disconnect these circuits before servicing.
When a photovoltaic panel is exposed to light, it generates a DC
voltage. When connected to this equipment, a photovoltaic panel
will charge the DC link capacitors.
Energy stored in this equipment’s DC link capacitors presents a risk
of electric shock. Even after the unit is disconnected from the grid
and photovoltaic panels, high voltages may still exist inside the PV-
Inverter. Do not remove the casing until at least 10 minutes after
disconnecting all power sources.
This unit is designed to feed power to the public power to the
public grid (utility) only. Do not connect this unit to an AC source or
generator. Connecting Inverter to external devices could result in
serious damage to your equipment.
Carefully remove the unit from its packing and inspect for external
damage. If you find any imperfections, please contact your local
dealer.
Although designed to meet all safety requirements, some parts and
surfaces of Inverter are still hot during operation. To reduce the risk
of injury, do not touch the heat sink at the back of the PV-Inverter
or nearby surfaces while Inverter is operating.

2.5.2 Commissioning
After the inverter reboot, LCD will produce the following messages in order:
‘Ser NO: xxx’->’xxxxx’->’FW version’->’Waiting’->’No AC connection’, the
display repeats ’NO Utility’ and LED will be red.
Close the AC breaker or fuse between PV-Inverter and grid. Turn on the DC
switch. The normal operating sequence begins.
Under normal operating conditions the LCD displays ‘Power: xxx.x W’. That is
the power fed to the grid. The LED turns green.
This completes the check.
2.6 System diagram
A
B
PV Panel: Provide DC power to inverter.
Converts DC (Direct Current) power from PV panel (s) to AC (Alternating
Current) power. Because Inverter is grid-connected it controls the current
amplitude according to the PV Panel power supply. Inverter always tries to
convert the maximum power from your PV panel(s).

CConnection system : This “interface” between Utility and PV-Inverter may
consist of electrical breaker, fuse and connecting terminals. To comply
with local safety standards and codes, the connection system should be
designed and implemented by a qualified technician.
Utility: Referred to as “grid” in this manual, is the way your electric power
company provides power to your place. Please note that Inverter can only
connect to low-voltage sysytems (namely,220_230VAC, 50/60Hz).
D
There are 3 different modes of operation.
3 Modes of Operation
3.1Normal mode
In this mode, Inverter works normally. Whenever the supplied power from PV panel is
sufficient (voltage>150VDC), Inverter converts power to the grid as generated by the
PV panel. If the power is insufficient, (voltage<100DC) Inverter enters a “waiting”
state. Whilst “waiting” Inverter uses just enough power from the PV panel monitor
internal system status. In normal mode the LED is green.
3.2 Fault mode
The internal intelligent controller can continuously monitor and adjust the system
status. If Inverter finds any unexpected conditions such as grid problems or internal
failure, it will display the information on its LCD and the LED will be red.
3.3 Shutdown mode
During periods of little or no sunlight, Inverter automatically stops running. In this
mode, Inverter does not take any power from the grid. The display and LED’s on the
front panel do not work.
Notes
Operating inverter is quite easy. During normal operation, Inverter runs
automatically with DC switch on. However, to achieve maximum conversion
efficiency of Inverter please read the following information:
a Automatic ON-OFF:
With DC switch on, Inverter starts up automatically when DC-power from the PV
panel is sufficient.
Once the PV - Inverter starts it enters one of the following 3 states:
1.Standby: The PV string can only provide just enough voltage to minimum
requirements of the controller.
2.Waiting: When the PV string DC voltage is greater than 100V, Inverter enters a
“waiting” state and attempts to connect to the grid.
3.Normal operation: When PV string DC voltage is greater than 150V, Inverter
operates in the normal state.
