Growatt UE 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 three-
phase. Growatt UE series inverters are multi-string inverters with multi-MPP trackers,
which mean they are able to connect to different PV module arrays.

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.
When design a PV system contains Growatt UE series inverters or any other Growatt
inverters, the system designing software ShineDesign (download from site:
www.ginverter.com) will provide adequate supports.

Growatt UE is designed to use worldwide, hence the inverters meet different safety
standards of variety countries and regions：
DANGER!
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.
CAUTION!
Danger of burn injuries due to hot enclosure parts!
During operation, the upper lid of the enclosure and the enclosure body may become
hot.
Only touch the lower enclosure lid during operation.
CAUTION!
Possible damage to health as a result of the effects of radiation!
Do not stay closer than 20 cm to the inverter for any length of time.
Grounding the PV generator
Comply with the local requirements for grounding the PV modules and the PV
generator.
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.
CAUTION!
Possible damage the PV modules as a result of Identification
of String Failure!
The GROWATT UE Inverter is equipped with a system which recognizes total failure of
individual strings or part-strings.

3.1 Selecting Mounting Location
This is guidance for installer to choose a suitable installation location, to avoid
potential damages to device and operators.
E
A
B
C
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 inverters’ dimension.
(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, nor
dust environment. That may derate the efficiency of the cooling fan
of the inverter; hence derate the efficiency of PV inverter.The
cooling fans and air grills should be cleaned every half or a year.
The Ingress Protection rate is IP65 which means the inverter can be
installed outdoors and indoors.

Do not expose the inverter to direct sunlight, in order to avoid the
power and efficiency derating caused by excessive heating.
The humidity of the installation location should be 0~95%
without condensation.
The ambient temperature of the inverter should be -25℃~+60℃.
The installation location must be freely and safely to get at all
times.
Vertically installation and make sure the connection of inverter
must be downwards. Never install horizontal and avoids forward
and sideways tilt.(Refer to drawings below)

Notice the minimum clearances of the inverter. (Refer to 3.2
Dimensions and Required Clearances).
Do not install the inverter near television antenna or any other
antennas and antenna cables.
Do not install the inverter in living area, the noise caused by the
machine may affect on daily life.
For security reasons, DON’T install the inverter in place where the
children can reach.

However, additional clearances are needed to guarantee running and operation of
the inverters. Especially when several inverters are installed together, the clearances
between the inverters and objects are necessary.
3.3 Mounting the Bracket
To mount the inverter on the wall, we should mount the bracket to the wall firmly
first of all.

Steps:
Drill holes for screws while use the mounting frame as template.6 holes for
Growatt 10000/12000UE and 8 for Growatt 18000/20000UE.
Fix the mounting frame on the wall as the figures shown below, combine as
the screws as the Items overview picture shows (items C, D, E, F).
Notes
mounting frame is really firmly mounted on the wall after carefully checking.

3.4 Mounting Inverter
After the bracket is firmly mounted on the wall, then mount the inverter on the bracket.
Hang the inverter on the bracket through the match hooks on bracket and the
back of the inverter.
4Electrical connections 
4.1 Wiring AC Output
Measure the public grid voltage and frequency (Voltage: 400Vac;
Frequency: 50Hz/60Hz; in 3-Phase);
Open the breaker or fuse between the PV inverter and utility;
Screw torsional force is 8 kg/cm;
Rise up the Growatt UE a little higher than the bracket. Considered the weight of
Growatt UE, you need handles (items G shown in chapter 2.1) to hang on the
inverter. During the process please maintain the balance of the Growatt UE.

6Operation Modes 
6.1 Normal Mode
In this mode, the inverter works normally and LED turns green.
Whenever the DC voltage is lower than 300Vac, the inverter will work in waiting
state and attempt to connect the grid. In waiting state the inverter consumes
just enough power generated by the PV panel to monitor the internal system
status;
Whenever the DC voltage is higher than 350Vac, inverter converts power to grid
as generated by the PV panels;

Notes:
sufficient.
The inverter starts up automatically when DC power from the PV panel is
6.2 Fault Mode
The internal intelligent controller can continuously monitor and adjust the system
status. If inverter finds any unexpected conditions such as system fault and inverter
fault, the fault information will be displayed on the LCD. In fault mode the LED turns
red.
Notes:
LCD. Detailed fault information refers to Chapter 9.2 ERROR messages displayed on
6.3 Shutdown Mode
Inverters automatically stop running during periods of little or no sunlight. In
shutdown mode the inverters take no power from the grid and panel, and the LCD
and LED turns off.
Notes:
Mode. If the PV string DC voltage is too low, the inverter will also turn to Shutdown
