○ Battery Protection Parameters

product-1044-1368

○ No DIP Switch Setting Required

The BMS has an automatic address assignment function (The DIP switch reserved on the BMS is just for show,

to be compatible with the original battery chassis port design. The DIP address is optional and does not affect

the BMS automatic address assignment);

Use conventional network cables for parallel connection. Connect the RS485B of any first unit to the RS485A

of the second unit (The first unit is the host, the host CAN/485 connects to the inverter communication).

Connect the RS485B of the second unit to the RS485A of the third unit, and so on. All subsequent units are

slaves. Example below:

○ Status Indication

product-1106-734

○ Basic Operating Modes

Charge Mode

When the BMS detects that a charger is connected and the external charging voltage is more than

0.5V higher than the internal battery voltage, it turns on the charge MOSFET to start charging. When the

charging current reaches the valid charge current, it enters charge mode. In charge mode, both charge

and discharge MOSFETs are closed.

Discharge Mode

When the BMS detects that a load is connected and the discharge current reaches the valid discharge

current, it enters discharge mode.

Standby Mode

If neither of the above two modes is met, it enters standby mode

Shutdown Mode

The BMS enters shutdown mode under the following conditions: normal standby for 48 hours,

battery triggers undervoltage protection, executing button shutdown, or external switch shutdown.

Shutdown mode wake-up conditions: 1. Charge activation; 2. 48V voltage activation; 3. Button power-on.

○ Packing List

product-1078-1268

○ Handling

When handling the packaged product or when it is lying flat, ensure the side with the cover and

display screen faces upwards; otherwise, consequences are your own responsibility; as shown below

○ Select Suitable Installation Location

 Do not place the battery on flammable building materials.

 Temperature should be between 10°C and 30°C for optimal operation.

 It is recommended to place the battery on a level ground surface.

 There should be some free space around the battery for heat dissipation (as shown below). Suitable for

placement on concrete surfaces or other non-flammable surfaces.

 For special environments, the heat dissipation space (battery spacing) can be appropriately adjusted.

Standard network cables suffice for multi-unit parallel connection, supporting up to 16 units for capacity expansion. Wiring and commissioning work are drastically simplified to boost construction efficiency.

3. Dual-Mode Intelligent Cell Balancing for Consistent Long Service Life

It supports both charge balancing and standby balancing to precisely narrow cell voltage gaps and slow capacity degradation. With wide-temperature charge & discharge capability, it operates stably from -20℃ to 40℃, fitting residential and complex outdoor scenarios.

2. Complete Fault Recording & Traceability for Hassle-Free Maintenance

The system stores up to 500 historical fault logs, fully recording anomalies including voltage deviations, abnormal temperatures and overcurrent. Multiple temperature sensors provide full-range monitoring for quick fault diagnosis and reduced after-sales maintenance workload.

4. Customizable Multi-Operation Logic for Diverse Grid Conditions

Built-in functions include current limiting, pre-charging, sleep mode and manual power on/off, with up to 48 hours standby protection. Users may customize charge/discharge thresholds and overcurrent protection parameters, perfectly matching India's weak grids and frequent power outages.
