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.

Do not install the PV-Inverter on a slanted surface.
Check the upper straps of PV-Inverter and ensure it fits on to the bracket.
Insert safety-lock screws to the bottom leg to secure the inverter (image 3).
Check the secure mounting of the PV-Inverter by trying to raise it from the
bottom. The PV-Inverter should remain firmly attached.
Select the installation location so that the status display can be easily viewed.
Choose a strong mounting wall to prevent vibrations while inverter is
operating

Measure the grid (utility) voltage and frequency. It should be 230 VAC (or
220VAC), 50/60Hz and single phase.
Open the breaker or fuse between PV Inverter and utility.
For Inverter, AC wires specifications as follows:
Model _(mm) Area(mm²) AWG no.

under any condition! Make sure the maximum open circuit voltage (Voc)
of each PV string is less than 450 VDC for Growatt 1000,Sunglod
1000,The length of input wire must be less than30m.
Use H4 or MC4 (Multi-contact) connectors for PV array terminals. Make
sure DC switch is off before connecting.
Connect the positive negative terminals from the PV panel to positive (+)
terminals and negative (-) terminals on the PV-Inverter. Each DC terminal
on Inverter can withstand 20ADC.
Before connecting PV panels to DC terminals, please make sure the
polarity is correct. Incorrect polarity connection could permanently
damage the unit. Checks short-circuit current of the PV string. The total
short-circuit current of the PV string should be less than the inverter’s
maximum DC current.
High voltages exist when the PV panel is exposed to the sun .To reduce
risk of electric shock, avoid touching live components and treat
connection terminals carefully.

2.5.1 Country selecting
When the PV panels are connected and their output voltage is greater than 70Vdc
but the AC grid is not yet connected, inverter will start up automatically. If it is the
first time to power on the inverter after installation, you may need to select a specific
country* .Otherwise, the interface will stay at the ‘Please Select’ interface all the
time. There are eleven options to select, as the list below.

Note: 1.If the country you want to select is not in the above list, please directly select
VDE0126-1-1.
2.The inverter can only be used for single grid-connected in the area where CEI 0-21
and VDE-AR-N4105 are requested to accord.
Please finish the country selecting according to the following steps:
The LCD will quickly switch to and stay at the ‘Please select’ interface
after power on, as Fig 2-5-1.

Single knock on the LCD, countries will vary from one to another along
the above list order. Fig 2-5-2 acts as an example, and Germany is the
second selection.
B

*If you have ordered the inverter with specific country settings, the parameters have been preset in factory
and you don't need to operate this step any more.

When you need to select any of these countries, you can Double knock to
enter the next interface. Here we select Italy as an example, as Fig 2-5-3.
C

When the country arrives at Italy, Double knock to enter the two options
‘YES’ and ‘NO’, and the cursor stays at ‘NO’ in default, as Fig 2-5-4.
D

Single knock to select ‘YES’, as Fig 2-5-5.
FDouble knock to confirm your selection, LCD will display ‘Select OK’ with
the country name in the below, as Fig 2-5-6.
Note: if you still single knock at the interface as Fig 2-5-5, the cursor will
go to ‘NO’ again as Fig 2-5-4, then if you double knock, the display will
switch to the interface as Fig 2-5-3.

Note: If you have selected and confirmed an unwanted country
neglectful, please contact Growatt for specific software to clear and reset
again.
When the selection is successful, the inverter will reboot automatically.
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

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>90VDC), Inverter converts power to the grid as generated by the
PV panel. If the power is insufficient, (voltage<70DC) 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 70V, Inverter enters a
“waiting” state and attempts to connect to the grid.
3.Normal operation: When PV string DC voltage is greater than 90V, Inverter
operates in the normal state.
