System structure

Outline structure

The appearance of the energy storage battery box is shown in Figure 1, with a chassis width of 395mm, a height of 150mm, and a depth of 550mm (excluding the handle).

Installation

Select the installation method according to preference on site. The common installation method is rack mounting. First place the battery pack correctly on the rack laminate, then use screws to fasten the battery pack to the rack using the lugs.

Depending on the number of batteries being used for the configuration, connect in multiple batteries in parallel if required Parallel connection requires connecting one batteries positive terminal to a second batteries positive terminal. Similarly, connect negative to negative.

Determine the positive and negative inputs of the load equipment/inverter. Connect the positive and negative terminals of the battery pack to the corresponding positive and negative inputs of the load equipment/inverter. Make sure that the positive and negative terminals are correctly connected, then turn on the battery switch.

Dipswitch Settings

When the battery pack is used in parallel, different battery packs can be distinguished by setting each battery’s address using the dip switch’s on the BMS. NOTE: Every battery should have a unique address. For the definition of BMS dip switch please refer to the following table:

Note: The LED indicator alarm can be enabled or disabled by the host computer. It is enabled by factory default.

Buzzer Action Description

When a fault occurs, the alarm rings for 0.25 seconds every 1S；
For protection, chirp every 2S 0.25s (except for overvoltage protection);
For alarms, the alarm is emitted every 3 seconds for 0.25 seconds (except for overvoltage alarms). The buzzer function can be enabled or disabled by a connected host computer. It is disabled by default.

Switch Operation

When the BMS is in sleep state, press the button (3 to 6S) and release it. The protection board will be activated, and the LED indicators will turn on for 0.5 seconds from “RUN”. When the BMS is in the active state, press the button (3~6S) and release it, the protection board will sleep, and the LED indicator will be lit for 0.5 seconds from the lowest power indicator. When the BMS is in the active state, press the button (6-10s) and release it. The protection panel will be reset and all LED lights will be on for 1.5 seconds at the same time. After the BMS is reset, the parameters and functions set by the upper computer are still retained. If the parameters need to be restored to the initial parameters, you can use the Restore Default value of the upper computer to achieve, but the relevant running records and stored data remain unchanged (such as power, cycle times, protection records, etc.).

Dormancy and Awaken

Dormancy:

When any of the following conditions are met, the system enters low-power mode:

1. Cell or Pack over-discharge protection has not been released within 30s.
2. Press the button for 3S-6S and then release it.
3. The lowest monomer voltage is lower than the sleep voltage, and the duration reaches the resting delay time (at the same time, no communication, no protection, no equalization, no current).
4. Standby time more than 24 hours (without communication, no charge and discharge, no mains power).
5. Through a connected host computer with forced shutdown. Before entering hibernation, make sure there is no charger access otherwise you will not be able to enter low-power mode.

Awaken:

When the system is in low-power mode and meets any of the following conditions, the system will exit low-power mode and enter normal operation mode:

1. Connect the charger. Output voltage of the charger should be greater than 48V.
2. Press the button (3S-6S) and release the button.
3. RS232 Communication activation
