Safety
1
Before using the inverter, please read all instrucons and cauonary
markings on the unit and manual.
Put the instrucons where you can take them easily.
The ESS inverter of ours strictly conforms to related safety rules in design
and test. Local safety regulaons shall be followed during installaon,
operaon and maintenance. Incorrect operaon work may cause injury
or death to the operator or a third party and damage to the inverter and
other properes belonging to the operator or a third party.

1.2 Safety Precauon
1.1 Symbols Used
• Installaon,maintenance and connecon of inverters must be
performed by qualied personnel, in compliance with local electrical
standards, wiring rules and requirements of local power authories
and/or companies
• To avoid electric shock, DC input and AC output of the inverter
must be terminated at least 5 minutes before performing any
installaon or maintenance.
• The temperature of some parts of the inverter may exceed 60°
Symbol Description
Danger of high voltage and electric shock!
Only qualied personnel may perform work on the inverter.
Danger of high voltage. Residual voltage in the inverter need
5 mins to discharge, wait 5 mins before operaon.

during operaon. To avoid being burnt, do not touch the inverter
during before touching it.
• Ensure children are kept away from inverters.
• Don’t open the front cover of the inverter. A part from performing
work at the wiring terminal (as instructed in this manual), touching
or changing components without authorizaon may cause injury to
people, damage to inverters and annulment of the warranty
• Stac electricity may damage electronic components. Appropriate
method must be adopted to prevent such damage to the inverter;
otherwise the inverter may be damaged and the warranty annulled.
• Ensure the output voltage of the proposed PV array is lower than
the maximum rated input voltage of the inverter; otherwise the
inverter may be damaged and the warranty annulled.
• When exposed to sunlight, the PV array generates dangerous high
DC voltage. Please operate according to our instrucons, or it will
result in danger to life.
• PV modules should have an IEC61730 class A rang.
• If the equipment is used in a manner not specied by the
manufacturer, the protecon provided by the equipment may be
impaired.
• Completely isolate the inverter before maintaining. Completely
isolate the inverter should: Switch o the PV switch, disconnect
the PV terminal, disconnect the baery terminal, and disconnect
the AC terminal.
• Prohibit to insert or pull the AC and DC terminals when the
inverter is running.
• Don’t connect ESS inverter in the following ways:
• EPS Port should not be connected to grid;
• The single PV panel string should not be connected to two or more
inverters.

The hybrid inverters are high-quality inverter which can convert solar
energy to AC energy and store energy into baery.
The inverter can be used to opmize self consumpon, store in the baery
for future use or feed into public grid. Work mode depends on PV energy
and user’s preference. It can provide power for emergency use during the
grid lost by using the energy from baery and inverter (generated from
PV).

3.2 Selecng the Mounng Locaon
3.2.1 Installaon Environment Requirements
a. The storage inverter protecon class is IP65 and can be mounted
indoors or outdoors.
b. The mounng locaon must be inaccessible to unrelated personnel
since the enclosure and heat sinks are extremely hot during operaon.
c. Do not install the storage inverter in areas containing highly ammable
materials or gases.
d. To ensure opmum operaon and long service life, the ambient
temperature must be below 50°C.
e. The storage inverter must be mounted in a well venlated environment
to ensure good heat dissipaon.
f. To ensure long service life, the storage inverter must not be exposed to
direct solar irradiaon, rain, or snow. It is recommended that the inverter
be mounted in a sheltered place.
g. The carrier where the inverter is mounted must be re-proof. Do not
mount the inverter on ammable building materials.
h. Do not install the inverter in a rest area since it will cause noise during
operaon.
i. The installaon height should be reasonable and make sure it is easy to
operate and view the display.
j. Product label and warning symbols shall be clear to read aer installaon.
k. Please avoid direct sunlight, rain exposure, show lay up install.

3.2.2 Mounng Requirements
3.2.3 Installaon Space Requirements
To ensure the inverter normally and easy to operate, there are requirements
on available spaces of the inverter, e.g. to keep enough clearance. Refer
to the following gures.
Mount the inverter vercally or lted backward by max 15°. The device
can not be installed with a wrong mode and the connecon area must
point downward.

Before mounng the inverter, you have to prepare expansion
bolts(specicaon: M12*80; Quanty: 3).
Step 1. Install the mounng bracket
1. Use a level ruler to mark the posion of the 3 holes on the wall. Refer
to Figure a. and drill 3 holes, 16mm in diameter and 55mm in deep. Refer
to Figure b.
2. Knock the expansion screw kit into the hole together with a hammer.
Refer to Figure c.
Note: Do not remove the nut unit in Figure c.
3. Aer ghtening 2-3 buckles, the expansion bolts are ght and not
loose, and then unscrew the bolts, spring washer, gasket. Refer to Figure c.
4. Install and x the mounng bracket on the wall. Refer to Figure d.
Step 2. Install the inverter on the mounng bracket. Then lock the
inverter using the security screw. Refer to Figure d.
3.3 Mounng

To prevent potential damages and injuries from inverter falling
down, please hang the inverter on the bracket, do not loosen grip
unless conrm the inverter is well mounted.
CAUTION
Before drilling the hole on the wall, ensure no damage on the
electric wire and/or water pipe inside the wall.
