under any condition! Make sure the maximum open circuit voltage (Voc)
of each PV string is less than 580 VDC for Growatt 4000, Growatt 4400,
Growatt 5000, Sungold 5000,less than 500 VDC for Growatt 2000,
Growatt 3000,Sungold 2000, Sungold 3000 and less than 450 VDC for
Growatt 1500, Sunglow 1500, The length of input wire must be less than
30m.
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 100Vdc
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:
If the country you want to select is not in the above list, please directly select
VDE0126-1-1.
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.

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.
