2 Safety
2.1 Important Safety Instructions
Danger!
Electric shock and high voltage.
Do not expose the storage unit to temperatures in excess of 45°C.
Do not subject the storage unit to any strong force.
Do not touch uninsulated cable termination.
Do not soak the storage unit
in water or expose it to moisture
environment.
Do not touch the case of the storage unit when it is wet in case of
electric shock.
Do not dispose of batteries in fire. The batteries may explode!
Do not place the storage unit near a heat source, such as direct
sunlight, a fireplace.
Keep inflammable and explosive dangerous items or flames away
from the storage unit.
Do not charge or discharge damaged storage unit.
Before performing any work on the storage unit, please disconnect
the storage unit
from all voltage sources as described in this
document.
Warning!
Installation, repair, recycling, and disposal of storage unit must be
performed by qualified personnel in accordance with national and
local standards and regulations.
Risks of chemical burn electrolyte or toxic gases.
Do not place heavy objects on the top of the system.
Do not connect any un-dedicated battery pack to TSUN storage
unit.
If the moisture penetrates the system (e.g., due to casing damage),
please do not install or operate the system.
Do not use wet hands to touch the system.

Any behavior to change the functionality of the product without
permission will cause fatal injury to the operator, third parties, and
equipment. TSUNESS is not responsible for these losses and
warranty claims.

5

To ensure property and personal safety, the batteries and inverter
shall be well grounded.
Caution!
Do not modify or tamper with storage unit and other components of
the system.
Risk of injury by hoisting or falling system

Inverters and batteries are heavy and personal injury can be
caused if the inverter or battery is improperly lifted or dropped
during transport or improper operation when attached or removed
from walls. Lifting and moved the products shall be conducted by
more than
one
person.
Note
！
Do not extend other brands of batteries at the battery port.
Storage unit outputs AC power directly to the utility grid and the
backup loads. Do not reverse output of these two AC terminals of
the inverter.
2.2 Explanation of Symbols
This section explains all the symbols shown on the inverter and on the type
label.
CE mark.
The inverter complieswith the requirements of the applicable CE guild
lines.
Dangerous electrical voltage
The device is directly connected to public grid, thus all work to the
battery shall only be carried out by qualified personnel.
No open flames
Do not place or install near flammable or explosive materials.
Corrosive substance
Keep the inverter away from corrosive substance.
Attention
Install the product out of reach of children

6
Danger of hot surface
The components inside the device will release a lot of heat during
operation. Do not touch metal plate housing of the inverter during
operating.
Danger.
Risk of electric shock!
An error occurred
Read the usage manual to troubleshoot problems
This device SHALL NOT be disposed of in residential waste
P
lease go to Chapter Seven “Battery maintenance” for proper
treatment.
Recyclable
2.3 Emergency situation
Despite of its careful and professional protection design against any hazard
results, damage of the battery may still occur. If a small amount of battery
electrolyte is released due to a serious damage of the outer casing; or if the
battery explodes due to not being treated timely after a fire breaks out
nearby, and leaks out poisonous gases such as carbon monoxide, carbon
dioxide etc., the following actions are recommended:
1) Eye contact: Rinse eyes with a large amount of running water and seek
medical advice
2) Contact with skin: Wash the contacted area with soap thoroughly and
seek medical advice
3) Inhalation: If you feel discomfort, dizziness or vomiting, seek medical
advice immediately.
4) Use a FM-200 or Carbon Dioxide (CO2) fire extinguishers to extinguish
the fire if there is a fire in the area where the battery pack is installed.
Wear a gas mask and avoid inhaling toxic gases and harmful
substances produced by the fire.
5) Use an ABC fire extinguisher, if the fire is not caused by battery and not
spread to it yet.

7
Potential danger of damaged battery:
Chemical Hazard: Despite of its careful and professional protection design
against any hazard results, rupture of battery shall still occur due to
mechanical damage, internal pressure etc., and may result in a leakage of
battery electrolyte. The electrolyte is corrosive and flammable. When there
is fire, the toxic gases produced will cause skin and eyes irritation, and
discomfort after inhalation. Therefore:
1) Do not open damaged batteries.
2) Do not damage the battery again (shock, fall, trample, etc.).
3) Keep damaged batteries away from water (except to prevent an energy
storage system from catching fire).
4) Do not expose the damaged battery to the sun to prevent internal
heating of the battery.
Electrical hazard: The reason of fire and explosion accidents in lithium
batteries is battery explosion. Here are the main factors of battery explosion:
1) Short circuit of battery. Short circuit will generate high heat inside
battery, resulting in partial electrolyte gasification, which will stretch the
battery shell. The temperature reaching ignition point of internal material
will lead to explosive combustion.
2) Overcharge of battery. Overcharge of battery may precipitate lithium
metal. If the shell is broken, it will come into direct contact with the air,
resulting in combustion. The electrolyte will be ignited at the same time,
resulting in strong flame, rapid expansion of gas and explosion.
Warning
!

If a fire has just occurred, try to disconnect the battery circuit breaker and
cut off the power supply first, but only if you can do so without endangering
yourself.

If the battery is on fire, do not attempt to extinguish the fire and evacuate
the crowd immediately.

3 Introduction
3.1 Scope of application
TSUN provide two kinds of storage unit product, AC Coupled Unit and Hybrid
Storage Unit. AC Coupled Unit doesn’t have PV inputs and is used in energy
storage retrofits.
Hybrid Storage Unit has two PV inputs and is used in new installation systems.
In daytime, solar power supports the loads first while the surplus power will be
stored by storage unit, to improve self-consumption rate.
In peak power price hours, power from storage unit supports the loads; while in
valley power price hours, storage unit is charged by the grid. Finally, a balance
could be realized.

9
In case of grid fault, storage unit will make sure no outage in the loads,
achieving UPS function.
Storage unit has two parts, inverter and battery. Storage unit can have a
capacity expansion according to user demands and the modular design of the
slave device makes it easy to install wiring.

Storage unit is cooled by natural wind convection. It is recommended to install
in indoors or sheltered areas to avoid direct sunlight, rain and snow.
Vertical ground mounting method is recommended and it’s allowed to be
installed by maximum tilting 15° backward. Do not install it horizontally or
reversely.

19
Please ensure that the air at the installation point is circulated. Bad air
ventilation will affect the working performance of internal electronic
components and shorten the service life of storage unit.
The following sites are not allowed for installation:
within 600mm of any exit.
