◆ The inverter only needs to communicate with the host (Pack1).
◆ When multiple batteries are connected with multiple inverters, it is best to connect
through the combiner box. If it is not connected through the combiner box, the
wiring mode shall be confirmed with the manufacturer's agent. And the cable from
each battery to the inverter remains the same length.
◆ Batteries are not allowed to be connected in series.
◆ Different batteries with different chemistries, different batches of batteries from the
same chemistry and technical design parameters can not be bundled and used
together.

Dormancy
BMS is in sleep state, press the key (3 ~ 6S) and release it, the protection
board is activated, and the LED indicator lights up successively from "run"
for 0.5 seconds.
BMS is in the active state. Press the key (3 ~ 6S) and release it, the protection
board is dormant, and the LED indicator lights up successively from the lowest
power light for 0.5 seconds.
BMS is active. Press the key (6 ~ 10s) and release it, the protection
board is reset, and all LED lights are on for 1.5 seconds at the same time.

Reset
After the BMS is reset, it still retains the parameters and functions set by the upper
computer. If it needs to be restored to the initial parameters, it can be realized
through the "restore default value" of the upper computer, but the relevant
operation records and stored data remain unchanged (such as power, cycle times,
protection records, etc.).
Explanation
5.2.4 Sleep and wake up
When any of the following conditions occurs, the system enters into the low
power consumption mode:
◆ Single or overall over discharge protection is not released within 30 seconds.
◆ Press the key (3 ~ 6S) and release the key.
◆ The minimum monomer voltage is lower than the sleep voltage, and the duration
reaches the sleep delay time (no communication, no protection, no balance and
no current).
◆ The standby time exceeds 24 hours (no communication, no charge and discharge,
no mains power).
◆ Forced shutdown by upper computer software.
Sleep:
To enable forced sleep mode, ensure that the input terminal is not connected to the external
voltage, otherwise it will not be able to enter the low power consumption mode.
Notice
Wake up:
When the system is in the low power consumption mode and meets any of the following
conditions, the system will exit the low power consumption mode and enter into the
normal operation mode:
◆ Connect the charger, and the output voltage of the charger shall be greater
than 48V.
(the battery voltage of 16 strings needs to be greater than 51.2V)
◆ Press the key (3 ~ 6S) and release the key.
◆ Activation of RS232 interface.
After single or overall over discharge protection, enter the low power consumption mode,
wake up regularly every 4 hours, and turn on the charge discharge MOS. If it can be charged,
it will exit the sleep state and enter normal charging; If the Automatic wake-up fails to
charge for 10 consecutive times, it will no longer wake up automatically.
When the system is defined as that the recovery voltage is not reached after 2 days of
standby (standby time setting value) after the end of charging, it is forced to resume
charging until the end of recharging.

7.Maintenance and replacement
◆ Please maintain the equipment when you are familiar with and understand the
contents of this manual and have appropriate tools and test devices.
◆ Before carrying out maintenance work, please power down the equipment first,
then follow the instructions of the delayed discharge label and wait for the
corresponding time to ensure that the equipment has been powered down before
operating the equipment.
◆ During maintenance, please try to avoid irrelevant personnel entering the
maintenance site, and temporary warning signs or fences must be erected for
isolation.
◆ If the equipment fails, please contact your dealer in time.
◆ The equipment can be powered on again only after the fault is handled, otherwise it
may cause fault expansion or equipment damage.
◆ Do not open the cover plate without authorization, otherwise there will be a risk of
electric shock, and the resulting failure does not belong to the scope of warranty.
◆ Operation and maintenance personnel and professional technicians shall be fully
trained in safe use and equipment maintenance, and shall operate with sufficient
preventive measures and personal protective equipment.
◆ Battery maintenance shall be performed or supervised by personnel familiar with the
battery and its required precautions.
◆ After the maintenance operation, check immediately to ensure that no tools or other
parts are missing in the equipment.
8.Battery storage requirements
◆ When the battery is stored, it shall be placed correctly according to the identification
of the packing box, and shall not be placed upside down or on the side.
◆ When the battery packing box is stacked, it shall meet the stacking requirements on
the outer package.
◆ The battery shall be handled with care, and it is strictly prohibited to damage the
battery.
◆ Storage environment requirements:
a. Ambient temperature: - 10 °C ~ 55°C, recommended storage temperature:
20 ? ~ 30 ?.
b. Relative humidity: 35% RH ~ 85% RH.
c. Dry, ventilated and clean.
d. Avoid contact with corrosive organic solvents, gases and other substances.
e. Avoid direct sunlight.
f. The distance from the heat source shall not be less than two meters.
◆ When the battery is stored, it must be disconnected from the outside. If there is an
indicator on the batter y panel, the indicator should be off.
◆ The warehouse keeper shall count the battery storage every month and regularly
report the battery inventor y to the planning link. For batteries with storage time close
to - 20 ~ 25°C = 6 months and - 20 ~ 45°C = 1 month, replenishment shall be arranged
in time. The battery shall be charged once every three months (under the normal storage
environment, long-term storage will lead to capacity attenuation and cycle life decline.
If it exceeds the storage environment requirements, it will further aggravate the capacity
attenuation and cycle life decline.)
◆ When the stored batteries are shipped, the principle of first in first out shall be followed.
30
◆ Battery maintenance shall be performed or supervised by personnel familiar with the
battery and its required precautions.
◆ After the battery production test is completed, it needs to be supplemented to 30-50%
SOC at least before storage.
9.Warranty products
Requirement:
During the warranty period, the company requires customers to provide invoices and
dates for purchasing products. At the same time, the trademark on the product shall be
clearly visible, otherwise it has the right not to provide quality assurance. The replaced
products shall be handled by the company, and the customer shall leave a certain time
for the company to deal with the faults.
10.Exemption from liability
The company has the right not to conduct quality assurance under the following
circumstances:
◆ Beyond the free warranty period.
◆ Incorrect installation, modification or use.
◆ Operate in very harsh environments beyond those described in this manual.
◆ Failure due to damage caused by unauthorized installation, repair, change or
disassembly.
◆ Failure due to damage caused by the use of non-standard components or software.
◆ Any installation and use beyond the scope specified in relevant international standards.
◆ Damage caused by abnormal natural environment.
