The Growatt MTL series inverters are grid-tied inverters which convert DC current
generated by PV modules into AC current and feed it into the public grid. The
Growatt MTL series inverters are multi-string inverters with multi-MPP trackers,
which meant they are able to connect to different PV module arrays.

Grid-tied PV System Overview:
As the drawing shown above, a complete Grid-tied PV system consists of PV modules,
PV inverters, distribution, grid and other components. Moreover, PV inverters always
act as key components.
Fig 1.3
When designing a PV system contains Growatt MTL series inverters or any other
Growatt inverters, the system designing software Shine Design (please download
from Growatt FTP. ftp://113.106.58.169, user name: ftpguest, password: ftpguest)
will provide adequate supports.
Notes
capacity relative to ground of the modules is large, please contact Growatt New

1.4 Safety
Growatt MTL is designed for global consumers, and is in accordance with most of the
safety standards of various countries and regions.
Below is the brief introduction of GFCI function and isolation function.

GFCI function
GFCI is short for Ground-Fault Circuit Interrupter which is used for preventing from
being electric shock.
The inverter is equipped with integrated RCD (Residual Current Protective Device)
and RCM (Residual Current Operated Monitor). The current sensor will detect the
volume of the leakage current and compare it with the pre-set value. If the leakage
current is above the permitted range, the RCD will disconnect the inverter from the
AC load.

Danger to life due to high voltages in the inverter!
All work on the inverter may be carried out by qualified personnel only.
The appliance is not to be used by children or persons with reduced physical, sensory
or mental capabilities, or lack of experience and knowledge, unless they have been
given supervision or instruction.
Children should be supervised to ensure that they do not play with the appliance.
Possible damage to health as a result of the effects of radiation!
DANGER!
CAUTION!

Image2
Possible damage to the PV modules as a result of Identification of String Failure!
The Growatt MTL Inverter is equipped with a system which recognizes total failure of
individual strings or part-strings.
CAUTION!
Comply with the local requirements for grounding the PV modules and the PV
generator.
Grounding the PV generator
PV Isolation Detection
The ISO function a protection mechanism.
The inverter measures the resistances between both the positive pole and negative
pole of PV panel and earth.
Either of the measured value is lower than the limit, the PV inverter will not connect
to grid, the output relay will stay open, and show ‘PV isolation low’. The limited value
is determined by the standards. The firmware setting of our PV inverters is 5Mohm.
The simplified principle of the isolation resistance measurement is described as
Image1 and Image2.
Do not stay closer than 20 cm to the inverter for any length of time.
Growatt recommends connecting the generator frame and other electrically
conductive surfaces in a manner which ensures continuous conduction and ground
these in order to have optimal protection of the system and personnel.

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
MTL 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 installation should be within -30℃
+60℃.
The installation location must be freely and safely to get for
operators or electricians at all times.

When the selection is successful, the inverter will reboot automatically.
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.
6Operation Modes
6.1 Waiting Mode
In this mode, inverter will check the system parameters. If the system is normal,
and PV voltage is higher than 150Vdc, the inverter will attempt to connect to
grid.
When the PV voltage is higher than 100V, Inverter will be powered up, and
enters “waiting” mode.
16 17

In this mode, Growatt MTL works normally and LED turns green.
6.2 Normal Mode
Whenever the DC voltage is lower than 120 Vdc, Growatt MTL inverter will work
in waiting state and attempt to connect the grid. In waiting state Growatt MTL
consumes just enough power generated by PV panels to monitor the internal
system status;
Whenever the DC voltage is higher than 150 Vdc, Growatt MTL inverter converts
DC Power generated by PV panels into AC power and feed it into grid;
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 MTL 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:

Growatt MTL automatically stop running during periods of little or no sunlight. In
shutdown mode Growatt MTL won’t take any power from the grid or panels, and LCD
and LED turns off.
