WARNING:
RISK OF ELECTRIC SHOCK AND FIRE . USE ONLY WITH PV MODULES WITH A
MAXIMNM SYSTEM VOLTAGE OF RATING!
WARNING:
ELECTRIC SHOCK HAZARD. THE DC CONDUCTORS OF THIS PHOTOVOLTAIC
SYSTEM ARE NORMALLY UNGROUNDED BUT WILL BECOME INTERMITTENTLY
GROUNDED WITHOUT INDICATION WHEN THE INVERTER MEASURES THE PV
ARRAY ISOLATION!
Under any condition! Make sure the maximum open circuit voltage (Voc) of
each PV string is less than 600Vdc for Growatt 2000 HF,Growatt 2500 HF and
Growatt 3000 HF.
The length of input wire must be less than 30m.
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.
Use MC (Muli-contact) connectors for PV array terminals
Connect the positive and negative terminals from the PV panel to positive (+)
terminals and negative (-) terminals on the PV-Inverter. Each DC terminal on
Inverter can withstand 15Adc for Growatt 3000 HF and Growatt 2500,12Adc for
Growatt 2000 HF.
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.

5.5 Commissioning Checking
When the PV panels are connected and their output voltage is greater than 100
VDC but the AC grid is not yet connected, the message on the LCD display
produce the following messages in order: “Growatt Inverter”-> “Waiting” -> “No
AC connection”. The display repeats “No AC connection” and the LED will be red.
Close the AC breaker or fuse between PV-Inverter and grid. The normal operating
sequence begins.
