Boot and sleep mode

Sleep mode: the battery will be in sleep mode if any of the following conditions are met

1. The battery or battery pack over discharge protection lasts for 30 seconds and is not released.
2. Press the power on / off button for 3 seconds and release.
3. The minimum voltage of the battery is lower than the “sleep voltage” setting in the setting, without charging and discharging.
4. Standby for more than 24 hours without charging and discharging.
5. Switch to the upper computer for sleep manually.

Wake up: the battery will exit sleep mode if any of the following conditions are met

1. Charger is plugged in; The charger voltage is greater than 48V.
2. Press the power on / off button for 3 seconds and release.
3. Plug in the communication cable and open the upper computer software (not available if it is under over discharge protection).

Note: if over discharge protection is enabled, the battery will be in sleep mode. The battery will wake up automatically every 4 hours and turn on the charge / discharge MOS. If charging is available, the battery will be charged, otherwise it will return to sleep mode. If it has been awakened 10 times but cannot be charged, the battery will not wake up again automatically.

Communication area

1. RS232: BMS can communicate with upper computer through RS232 interface, so as to monitor various information of battery, including battery voltage, current,temperature, status and battery production information, etc. the default baud rate is 9600bps.
2. RS485: with dual RS485 interface, you can view the information of pack. The default baud rate is 9600bps.If it is necessary to communicate with the monitoring equipment through RS485, the monitoring equipment is used as the host, polling data according to the address, and the address setting range is 1 ~ 15.
3. CAN: CAN communication, baud rate 9600bps.
4. DCT：dry contact interface.
5. Rst: reset button.
6. ADS: dial switch

Parallel connection diagram

If parallel batteries are required, connect the wires according to the diagram，maximum support for 15 batteries in parallel

Description of parallel connection

The signal line connected to the inverter should use RS485 communication line or CAN communication line. If it is necessary to use batteries in parallel:

1. RS485 cable shall be used to connect the parallel communication port. Refer to the communication line parallel diagram;
2. The address of the battery needs to be set. Refer to the dial switch setting table for address setting

Product list and tools

Product packing lists

Home energy storage system series power supply has been strictly inspected before delivery, but may be damaged in transit, therefore, after unpacking the box, please check whether the following items are complete, confirm the model, capacity, input voltage and output voltage, and whether the specified content when ordering; If anything abnormal or inconsistent occurs, please contact the distributor as soon as possible.

Instruction manual

1. Place the battery in an appropriate position, plug the positive/negative connector into the positive/negative socket.
2. Connect the other end of the positive and negative lead to the inverter.
3. Turn on the Rocker switch and the Air Switch.

Active Equilibrium Function

Overview

Because the battery capacity, internal resistance, voltage and other parameter values are not completely consistent, this difference causes the battery with the smallest capacity to be easily overcharged and discharged during charging, and the smallest battery capacity becomes smaller after damage, entering a vicious cycle. The performance of single battery directly affects the charge and discharge characteristics of the whole battery and the reduction of battery capacity. BMS without balance function is just a data collector, which is hardly a management system. BMS active equalization function can realize the maximum continuous 1A equalization current.

Transfer the high-energy single battery to the low-energy single battery, or use the whole group of energy to supplement the lowest single battery. During the implementation process, the energy is redistributed through the energy storage link, so as to ensure the battery consistency to the greatest extent, improve the battery life mileage and delay the battery aging.
