5. Electrical Connection
5.1 System Connection Precautions
Note!
This battery must be used in conjunction with compatible hybrid inverter models. It needs to establish
communication with the inverter to activate the lithium battery mode, ensuring optimal battery
performance.If used with an unmatched inverter, ensure that the maximum operating current does not
exceed 160A for charging and 180A for discharging at an ambient temperature of 25±2°C.
When connecting to inverters or being in parallel mode, please use cables provided in the unpacking list.
If other cables must be used in special cases, ensure they meet FCC standards.
5.2 Preparation before Wiring
Note!
It is noted to distinguish the positive and negative ends of cables.
Be careful to avoid misuse of lines used for communication between PCS and battery, battery and

The battery product should be stored in a dry, cool, and cool environment;
If the battery is stored for long time, it is required to charge them every six months, and the SOC
should be no less than 50%.
Generally, the maximum storage period at room temperature is 6 months. When the battery is stored
over 6 months, it is recommended to check the battery voltage. If the volt age is higher than 51.2V, it
can continue to store the battery. In addition, it is needed to check the voltage at least once a month
until the voltage is lower than 51.2V. When the voltage of the battery is lower than 51.2V, it must to be
charged according to the charging strategy.
When the battery product is stored, the source of ignition or high temperature should be avoided and
it should be kept away from explosive and flammable areas.
If your batteries need to be charged or discharged in lead-acid mode,maintain a charge/discharge
current of 0.2C within a temperature range of 5°C to 45°C.

9 Troubleshooting
To determine the status of the battery system, users must use additional battery status monitoring
software to examine the protection mode. Refer to the installation manual about using the monitoring
software. Once the user knows the protection mode, refer to the following sections for solutions.
Fault Type Phenomenons Possible Causes Solutions
Information
collection fails
The cell voltage
sampling circuit is
faulty.
The cell temperature
sampling circuit is
faulty
The welding point for cell
voltage sampling is loose or
disconnected.
The voltage sampling terminal
is disconnected.
The cell temperature sensor
has failed.
Replace the
collection line.
Electrochemical
cell error
The voltage of the cell
is low or unbalanced.
Due to large self- discharge,
the cell over discharges to
below 2.0V after long term
storage.
The cell is damaged by external
factors, and short circuits,
pinpricks, or crushing occur.
Replace the
battery.
Over-voltage
protection fails
The cell voltage is
greater than 3.65 V in
charging state.
The battery voltage is
greater than 58.4 V.
The busbar input voltage
exceeds the normal value.
Cells are not consistent. The
capacity of some cells
deteriorates too fast or the
internal resistance of some
cells is too high.
If the battery
cannot be
recovered due to
protection against
abnormality
contact local
engineers to
rectify the fault.
Under voltage
protection fails
The battery voltage is
less than 44.8V.
The minimum cell
voltage is less than
2.8V
The mains power failure has

11 Environmental Disposal
Used batteries can not be disposed of as household waste. You are obliged to handle waste batteries,
such as removal of privacy on product, and return them to designated or authorized recovery point
according to applicable regulations and standards on waste battery disposal.
Attention:
1. Do not dispose of batteries and rechargeable batteries as domestic waste!
You are legally obliged to return used batteries and rechargeable batteries.
2. Waste batteries may contain pollutants that can damage the environment or your health if improperly
stored or handled.
3. Batteries also contain iron, lithium and other important raw materials, which can be recycled.
For more information, please visit http://www.deyeess.com. Do not dispose of batteries as

1. The battery products should be transported after packaging and during the transportation process.
Severe vibration, impact, or extrusion should be prevented to prevent sun and rain. It can be transported
using vehicles such as cars, trains, and ships.
2. Always check all applicable local, national, and international regulations before transporting a Lithium
Iron Phosphate battery.
3. Transporting an end-of-life, damaged, or recalled battery may, in certain cases, be specially limited or
