1.2 Safety guide
• After receiving this product, first confirm the product package is intact. If
any question, contact the logistic company or local distributor
immediately.
• The installation and operation of the machine must be carried out by
professional technicians who have received professional trainings, and
thoroughly familiar with all the contents in this manual and the safety
requirements of the electrical system.
• Do not carry out connection/disconnection, unpacking inspection and
unit replacement operations on the machine when power source is
applied. Before wiring and inspection, users must confirm the breakers
on DC and AC side of inverter are disconnected and wait for at least 5
minutes
• Ensure there is no strong electromagnetic interference caused by other
electronic or electrical devices around the installation site.
• Do not refit the machine unless authorized.
• All the electrical installation must conform to local and national electrical
standards.
• Ground with proper technics before operation
• Do not open the surface cover of the machine unless authorized. The
electronic components inside the machine are electrostatic sensitive. Do
take proper anti-electrostatic measures during authorized operation.
• Do not touch the housing of the machine or the radiator to avoid scald
as they may become hot during operation
• The machine needs to be reliably grounded.
• Ensure that DC and AC side circuit breakers have been disconnected
and wait at least 5 minutes before wiring and checking.
Note: Technical personnel who can perform installation, wiring, commissioning,
maintenance, troubleshooting and replacement of the energy storage inverters must
meet the following requirements:
• Operators need professional training.
• Operators must read this manual completely, and master the related safety
precautions.
• Operators need to be familiar with the relevant safety regulations for electrical
systems.
• Operators need to be fully familiar with the composition and operating principle of the
entire energy storage system, and related standards of the countries/regions in which
the project is located.
• Operators must wear personal protective equipment.

1.2.1 Transportation and installation
1.2.2 Grid-tied operation
Note
• Only qualified electricians are allowed to operate the machine under
the permission of local power departments.
• All electrical connections must meet the electrical standards of the
countries/regions in which the project is located.
• Ensure reliable installation and electrical connection before operation.
• Do not open the cover of the machine when the machine is working or
any circuit is connecting to the machine.
• Keep the package and unit complete, dry and clean during storage
and transportation.
• This machine is heavy. Please remove and install it with at least
Two people.
• To ensure the normal and safe operation of the energy storage
integrated machine and avoid personal injury, please select proper
handling and installation tools, and take mechanical protection
measures to protect personal safety, such as wearing smashing
shoes, coverall and so on.
• Only qualified electricians are allowed to install the machine.
• Do not put and install the machine on or close to flammable or
explosive materials.
• Do not install the machine in a place where children and other people
can easily touch it.
• To avoid a risk of electric shock, please remove rings, bracelets, and
other metal jewelry on your hands before installation and electrical
connection.
• The solar cell modules exposed to the sunlight may generate
dangerous voltage. Users must cover the cell modules with fully light
shading materials before electrical connection.
• The input voltage of the machine should not exceed the maximum
input voltage, otherwise damage may occur.
• The machine is not suitable for the positive or negative grounding
systems of solar cell modules.
• Ensure the proper grounding of the inverter.
• Ensure reliable installation and electrical connection.

8
1.2.3 Maintenance and replacement
• Only qualified electricians are allowed to perform the maintenance,
inspection, and component replacement of the machine.
• Please contact the distributor or manufacturer for maintenance.
• In order to avoid irrelevant personnel from entering the maintenance
area during maintenance, temporary warning signs must be placed
to warn non-professionals to enter or use fence for isolation.
• Before carrying out any maintenance operations, all input power to
the machine must be disconnected first, and wait for at least 5
minutes until the internal parts of the machine are fully discharged.
• Please follow the electrostatic protection norms, and take correct
protective measures because there are mostly electrostatic
sensitive circuits and devices in the machine.
• Do not use parts and components not provided by our company
during maintenance.
• Restart the machine after eliminating the faults and problems which
may affect the safety and performance of the machine.
• Do not get close to or touch any charged metal conductor parts of
the grid or running system, otherwise electric shock or fire may
occur. Please do not ignore the warning icons and instructions with
“electric shock”.
1.2.4 What to do after scrapping
• Do not dispose of the machine together with household waste. The
user has the responsibility and obligation to send it to the designated

2.4.2 Working mode
SOLUNA S12 EU have the below working modes for your home made energy
storage system.
●Self Use
In the “Self Use” mode the priority of the PV generated power will be :local
load>battery >public grid. It means the PV generated power will be used in local
load then the battery charging and the redundancy power will be delivered to the
public grid.
●Peak shaving Use
In the “Force Time Use” mode ,user can set the charging and discharging time
according to his wishes and also can chose if charge from grid if allowed.
●EPS mode
The SOLUNA S12 EU version integrated with EPS function. The inverter will
automatically switch to EPS output when the grid if off. User need to set the battery
remaining value for the EPS. When use the EPS function, need to fit the load
power rating with the EPS power rating
