2. Safety
2.1. Intended Use
The battery system is for residential and works with a
photovoltaic system. It is a high voltage Li-ion battery
storage system, with the control unit on itself. It could
be operated in on-grid, off-grid and backup modes with
compatible inverters.
The battery system could be connected to the Internet
through network cable for maintenance and rmware
updating.
The battery system must only be used as stationary
equipment.
The battery system is suitable for indoor and outdoor use
under the conditions mentioned in Section 5.1.
The battery system is not suitable for supplying life-
sustaining medical devices. Please ensure that no
personal injury would occur due to the power outage of
the battery system.
Alterations to the battery system, e.g., changes or
modications are not allowed unless the written
permission of GBAis achieved. Unauthorized alterations
will void the guarantee and warranty claims. GBAshall
not be held liable for any damage caused by such
changes.
The type label should always be attached to the battery
system.
The battery system must only be operated in connection
with a compatible inverter. The list (WTS
CORE Series
Battery Compatible Inverter List) of these
inverters
could
be found at

2. Safety
Inhalation:
Eye contact:
Skin contact:
Ingestion:
Rinse eyes with owing water for
15 minutes and seek medical help
immediately.
Wash the affected area thoroughly with
soap and water and seek medical help
immediately.
Induce vomiting and seek medical help
immediately.
2.2. IMPORTANT SAFETY INSTRUCTIONS
The battery system has been designed and tested in
accordance with international safety requirements.
However, in order to prevent personal injury and
property damage and ensure long-term operation of
the battery system, please do read this section
carefully and observe all safety information at all times.
2.2.1. Battery Stack Leakage
If the battery stacks leak electrolytes, contact with the
leaking liquid or gas should be avoided. The electrolyte
is corrosive, and the contact may cause skin irritation
and chemical burns. If one is exposed to the leaked
substance, do these actions:
Evacuate the contaminated area, and
seek medical help immediately.

2. Safety
2.2.2. Fireghting Measures
The battery stacks may catch re when it is put into
the
re. In case of a re, please make sure that an ABC or
carbon dioxide extinguisher is nearby. Water cannot be
used to extinguish the re.
Full protective clothing and self-contained breathing
apparatus are required for the reghters to extinguish
the re.
2.2.3. Battery Stacks Handling and Storage Guide
•
The battery stacks and its components should be
protected from damage when transporting and
handling.
•
Do not impact, pull, drag, or step on the battery
stacks.
•
Do not insert unrelated objects into any part of the
battery stacks.
• Do not throw the battery stack into a re.
• Do not soak the battery stacks in water or seawater.
• Do not expose to strong oxidizers.
• Do not short-circuit the battery stacks.
•
The battery stacks cannot be stored at high
temperatures (more than 55°C).
•
The battery stacks cannot be stored directly under
the sun.
•
The battery stacks cannot be stored in a high
humidity environment.
•
Do not use the battery stacks if it is defective, or
appears cracked, broken or otherwise damaged, or
fails to operate.
•
Do not attempt to open, disassemble, repair, tamper
with, or modify the battery stacks. The battery
stacks
are not user-serviceable.
•
Do not use cleaning solvents to clean the battery
stacks.

2. Safety
2.2.4. Warning of Electric Shock
DANGER
DANGER
2.2.5. Warning of Overvoltage
Danger to life due to electric shock in case of overvoltage and if surge protection is missing
Overvoltage (e.g. in the event of a ash of lightning) can be
further conducted into building and to
other connected devices in the same network via the network cables or other data cables if there
is no surge protection. Touching live parts and cables
results in death or lethal injuries due to
electric shock.
•
When laying the network cables or other data cables outdoors, it must be ensured that a
suitable surge protection device is provided at the transition point of the cable from the battery
system or the inverter outdoors to the inside of a building.
Danger to life due to electric shock when live components or DC cables are touched
The DC cables connected to an inverter may be live. Touching live DC cables results in death or
serious injury due to electric shock.
•Disconnect the battery system and inverter from voltage sources and make sure it cannot be
reconnected before working on the device.
•Do not touch non-insulated parts or cables.
•Do not remove the terminal block with the connected DC conductors from the slot under load.
•Wear suitable personal protective equipment for all work on the battery system.
•Observe all safety information of the inverter manufacturer.

2.2.6. Caution of Weight
2.2.7. Notice of Property Damage
CAUTION
NOTICE
Risk of injury due to the weight of the battery stack
Injuries may result if the battery stack being lifted incorrectly
or dropped while being transported
or installed.
•
Transport and lift the battery stack carefully. Take the weight of the battery stack into account.
•
Wear suitable personal protective equipment for all work on the battery system.
Damage to the BMS due to sand, dust and moisture ingress
Sand, dust and moisture penetration can damage the BMS and impair its functionality
•
Only open the BMS if the humidity is within the thresholds and the environment is free of sand
and dust.

4.1. Battery System Description
The WTS CORE Series battery product is used as a
connected battery for the intermediate storage of
excess PV energy in an inverter system.
BMS, short for Battery Management System, is the control unit of the product.
There are two types of battery stacks, WTS Power-CORE and WTS Energy-CORE. The
former one
has
a
higher rated power while the later one has a higher rated usable
energy.
Two to ve
WTS Power-CORE battery stacks or three to eight
WTS Energy-CORE battery
stacks
could
be installed in one tower, and maximum of six towers could be
connected in parallel.
These two battery stacks cannot be mixed up in operation.
