1>Do not unpack the inverter and store it in a ventilation dry place .
2>Keep the storage temperature at -30 ℃- +60℃ and humidity at 0-100%.
3>A maximum of three inverters with package can be stacked.
4>If the inverter has been long-term stored, inspections and tests should be conducted
by qualified personnel before it is put into use.
After being stored for a month or longer, the inverter's time and date
could be wrong, you need set the time and date before using, for
more details please refer to Chapter 7.1 inverter commissioning

3.7 AFCI Detection Function
AFCI (Arc Fault Circuit Interrupter) is a kind of circuit protection device, the main
function is to prevent the fire caused by fault arc.The electrical insulation aging,
breakage, loose connection, air breakdown caused by air humidity and so on, all of these
may cause an electric spark, which is called arc.
The AFCI function of the MAX 175-253KTL3-X HV series inverter is optional, and the
detection equipment is assembled inside the inverter. When an arc-drawing condition is
detected on the PV input side, the arc current could be detected by the CT assembled on
the PV input-side wire. Then the inverter will shut down. Meanwhile, the inverter will
display the corresponding fault message and the buzzer will sound, which could help to
avoid harm and economic loss to the user.
NOTE: AFCI function is optional.
Unpacking 4
Checking before installation
1>Before unpacking the inverter, check the outer packing materials for damage.
2>After unpacking the inverter, check that the contents are intact and complete. If any
damage is found or any component is missing, contact your supplier.

In MAX 175-253KTL3-X HV series inverters, RS485 interface is standard. The connection
steps of RS485 communication line are as follows:
1) Unscrew the waterproof cover of the COM interface and remove it.
2) Connect the RS485 communication line to the port of 485-1.
3) The inverter is connected hand in hand through the RS485 communication line, and
the end of the communication line 485_A/B is connected to the monitoring equipment to
realize multi-machine remote monitoring.
Note: When locking the RS485 cable screw, the torque is 4kgf·cm.
Fig 6.7
The MAX 175-253KTL3-X HV series inverters are equipped with a USB interface as
standard, which can be connected to a USB to WIFI module, Shine GPRS-X2, Shine WIFI-
X, Shine 4G-X, Shine Link-X and other optional monitoring modules to realize remote
Monitoring function. In addition, you can also quickly upgrade the inverter software
through the U disk:
Steps to install the monitoring module:
1> Loosen the waterproof cover of the USB interface and remove it.
2> As shown in Figure 6.8A, insert the Shine GPRS-X2 module into the USB interface,
and the LED of the Shine GPRS-X2 module will be on.
3> As shown in Figure 6.8B, make sure that the △ is facing upwards, insert the
monitoring module into the USB interface, and tighten the lock.
Note: If you use a USB to WIFI module, when the operator leaves, please take the module
and the data cable away, and tighten the waterproof cover to prevent water from
entering the interface.

According to the relevant provisions of IEC 61643-32 "Connecting to photovoltaic
devices surge protectors - selection and use of guidelines", whether for household or
outdoor photovoltaic power plants, it is necessary to ensure the implementation of
lightning protection measures for photovoltaic systems:
6.4 Connecting The Ground Cables
In this solar system all the unloaded metal components and cases should be connected to
the ground. Single inverter need grounding over a PE point, multiple inverters need
connect all the inverter PE cable and solar panels shelves to the same grounding point to
achieve equipotential.
The grounding steps as following:
Take out the ground screw at the inverter bottom, connect the ground cables as
following figure.
Notice: 1.The machine is safely separated from the lightning protection and the distance
is as far as possible.
2.Do not expose Grounding terminal in the air and precaution for the rain.
3.When you lock the case ground screw, the torque force should be 60kgf·cm.
Fig 6.9
WARNING
The lightning protection measures for photovoltaic systems shall be
carried out in accordance with the corresponding national standards
and IEC standards. Otherwise, photovoltaic devices such as
components, inverters and power distribution facilities may be
damaged by lightning.
In this case, the company does not carry out warranty and assumes
any responsibility.

Fig 6.10
1)It is generally recommended to install lightning protection devices (such as lightning
rods / lightning protection belts and down conductors) to prevent lightning from hitting
the PV array.
2)Lightning protection devices and down-conductors and related equipment in
Suggested value of S: According to the general 5 storey height (about 15m) building
roof, S takes 2.5m enough, this distance can be simplified according to the inverse
relationship of the floor height.
A. When the safety distance S is satisfied:
The position ①③ of the figure should be equipped with a lightning protection module. In
general, it is recommended to install Type II in position ① and Type I in position ③.
B. When the safety and safety distance S is not met:
In addition to position 3, Type I lightning protection module should be installed in Figure
①②④.
3)The lightning down conductor and the equipment ground wire eventually sink at a
total ground point, but the two cannot share the wire. That is, the equipment grounding
wire should be pulled separately, and the wire diameter requirement >6mm² when the
safety interval distance S is satisfied.

distributor and installer can apply for the OSS account from Growatt. Click "Sign in"
to set the password. After the setting is successful, you can start using it.)
3>Click top item “COM Address”;
4>Click the "Read" button in the upper right corner to read the current communication
address of the inverter;
5> Set inverter com address;
6>Read inverter com address to ensure setting is successful;
The inverter will be set to the appropriate model according to the standards of different
countries or regions before leaving the factory. For example, the inverters shipped to
Australia are configured as Australian model in the factory.
Note: The inverter is configured for Australia at the factory.

7.1.2 Set inverter time and date
Please refer to section 8.2.1 and login ShinePhone APP.Click "system time(45-50)"to set
inverter time and date on the parameter setting page.
7.2 Operation Mode
Fig 7.2
7.2.1 Waiting mode
7.2.2 Working mode
When the DC voltage is more than 500Vdc, inverter will be powered on and enters the
"waiting" state.
At this mode, inverter will check the system parameter. If the system is normal and PV
voltage is more than 500Vdc, inverter will try to connect to the grid.
At this mode, inverter work normally,and the shows the power delivered by the inverter
to the grid.
When the DC voltage is more than 500Vdc,inverter converts the DC power generated by
the PV modules into AC power and supplies them to the grid.
When the DC voltage is lower than 500Vdc, inverter will enter into “waiting” state and
try to connect to the grid, at this status, inverter consume very small power to check the
internal system status.
Note: only when the PV modules supply enough power(voltage＞ 500Vdc) then the
inverter will start automatically.

7.3 LED Display
7.2.3 Fault mode
7.2.4 Off mode
Inverter intelligent control system will continuously monitor and adjust system
status.When there is a fault detected, LED will show the fault message.
Note: Please refer to section 9.2 to check the fault message and take corrective
measures.
When the sunlight is weak or no light, inverter will stop working automatically. When it is
off, inverter will not consume gird power or PV module. At the same time, the LED of
inverter will be turned off.
Note: When PV string DC voltage is too low(≤500Vdc), inverter will be off.
Inverter current operation status can be visually checked from LED display directly.

state
The eight LEDs from left to
right represent the power of
the inverter: if 8 green lights
are on, it represents 100%
of the inverter power. As
shown in Figure 7-3, it
represents 37.5% of the
inverter power, and so on.
Inverter is in fault state
The 8 LED lights from right to
left represent the fault codes
currently reported by the
inverter. From right to left,
they represent 1, 2, 4, 8, 16,
32, 64, and 128. For example,
the first and fourth green
LEDs on the right are always
on, which means 1+8=9. In
addition, add 200 to get 209,
which means the inverter
reports fault 209, and so on.
Note: For related fault codes, please refer to 9.2 Trouble shooting
