Growatt HF series inverters are grid-tied inverters which convert DC current
generated by PV modules into AC current and feed it into the public grid in single-
phase. Growatt HF inverters are multi-string inverters with high frequency
transformer for galvanic isolation, with the specially designed integrated high
frequency transformer and wide input voltage range Growatt HF are able to be
connected to different panels (e.g. monocrystal, polycrystal silicon panels and thin-
film panels).

Grid-tied PV System Overview:
As drawings shown above, a complete grid-tied PV system consists of PV modules, PV
inverters, public grid and other components. Moreover, PV inverters always act as key
components.
Fig 1.3
The Growatt HF inverters may only be operated with PV generators (modules and
cabling) with protective insulation. Don't connect any sources of energy other than
PV modules to the Growatt HF inverters.
When your PV system contains Growatt HF inverters or any other Growatt inverters,
the PV system design software ShineDesign will provide adequate supports.

Notes
range, Growatt HF is very suitable for thin-film systems or any other PV systems that
requires NEGATIVE GROUND or GALVANIC ISOLATION.
: Because of the high frequency transformer isolation and wide input voltage
1.4 Safety
Growatt HF is designed for global consumers, and is in accordance with most of the
safety standards of various countries and regions.

The wall selected to install the inverter must be strong and firm
enough to support and bear the weight of the inverter for a long
period time. (Refer to Chapter 10 Specifications)
The location selected must be suitable for dimensions of Growatt
HF. (Refer to 3.2 Dimensions and Required Clearances)
Do not install the inverter on structures constructed of flammable
or thermolabile materials.
never install the inverter in environment of little or no air flow, or
environment of dust. That may derate the efficiency of heat
dissipation, which will derate the conversion efficiency of inverters.
The Ingress Protection rate (IP level) is IP65 which means Growatt
HF can be installed both indoors and outdoors.
Do not expose the inverter to direct sunlight, in order to avoid the
power and efficiency derating caused by excessive heating.
The humidity of location should be within 0~95% and without
condensation.

The ambient temperature of the inverter should be -25℃~+60℃.
The installation location must be freely and safely to get for
operators or electricians at all times.
Vertically installation and make sure the connection of inverter is
downward. Never install horizontal and avoids forward and
sideways tilt, refer to drawing below.
Notice the minimum clearances of the inverter. (Refer to 3.2
Dimensions and Required Clearances)
Do not install Growatt HF near television antenna or any other
antennas and antenna cables, for possible interferences of
inverter or cables.
Do not install Growatt HF in living area, the noise caused by
inverter might affect on daily life.
For security reasons, DO NOT install Growatt HF in place where the
children can reach.

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”-> “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.
Under normal operating conditions the LCD displays “Power: xxxx.xW”.
That is the power fed to the grid. The LED turns green.
Finish commissioning.

6Operation Modes
6.1 Waiting Mode
In this mode, Growatt HF works normally and LED turns green.
In this mode, inverter will check the system parameters. If the system is normal,
and PV voltage is larger than 150Vdc, the inverter will attempt to connect to
grid.
When the PV voltage is greater than 100V, Inverter will be powered up, and
enters “waiting” mode.
6.2 Normal Mode
Whenever the DC voltage is lower than 120 Vdc, Growatt HF inverter will work
in waiting state and attempt to connect the grid. In waiting state Growatt HF
consumes just enough power generated by PV panels to monitor the internal
system status;
Whenever the DC voltage is higher than 150 Vdc, Growatt HF inverter converts
power to grid as generated by PV panels;
Notes:
sufficient (100 Vdc).
The inverter starts up automatically when DC power from PV panels is
6.3 Fault Mode
The internal intelligent controller can continuously monitor and adjust the system
status. If Growatt HF finds any unexpected conditions such as system fault and
inverter fault, the fault messages will be displayed on LCD screen. In fault mode the
LED turns red.
Notes:
LCD.
Detailed fault information refers to Chapter 9.2 ERROR messages display on
6.4 Shutdown Mode
Growatt HF automatically stop running during periods of little or no sunlight. In
shutdown mode Growatt HF won’t take any power from the grid or panels, and LCD
and LED turns off.
Notes:
Shutdown Mode.
If the PV string DC voltage is too low (≤70 Vdc), the inverter will also turn to
