DIP switch description:

When the battery pack is connected in parallel, the host can communicate with the slave through the CAN interface. The host summarizes the information of the entire battery system and communicates with the inverter through CAN or 485. The connection mode is divided into the following two cases:

1. If the host is the latest model battery with DIP switch:

2. The communication cable that communicates with the inverter should use the correct one.

3. After the battery module parallel cable, cascading cable and communication cable with GDW、Solis、 LUX、Sofar、DEYE、VICTRON、IMEON、Infinisolar, Sungrow, SMA,RENAC,DELIOS、SAJ(CAN Comm) inverters are connected, all batteries should not be turned on first, be sure to put the host DIP switch “# 3” to the “ON” position (to the top), then turn on all the batteries.

4. If the battery module is in communication with the inverters of Growatt hybrid(CAN comm)、GMDE、 Saj(485 comm), turn the host DIP switch “#2” to “ON” position.

5. If the battery module is in communication with the GROWATT-SPF(off-grid inverter) by 485 communication, turn the host DIP switch “#2” and “#3” to “ON”.

6. If the battery module is in communication with the ICC by 485 communication, turn the host DIP switch “#1” and “#4” to “ON”.

7. the DIP switch of the slaves need to turn the “#4” to “ON”.

8. The DIP switch of the slaves no need to be changed.

9. If the energy storage system has only one battery unit, it is the host itself, and still follow the above steps.
   Note: For more information of matching inverter brands, please subject to the latest document .

10. If the host is a battery module without the DIP switch:

11. The communication cable that communicates with the inverter should use the correct one which is offered by GSL.

12. After the battery module parallel cable, cascade cable and the inverter communication cable are connected, turn on all batteries.

13. Before connecting with inverter, please ensure the no-dip battery firmware version support yours inverter.

Caution ：The DIP switch mode in case (5),1001&0001 is only for ICC (a special commnunication device of some no-communication inverter), it’s a special firmware in battery BMS, different from general firmware, so if customers want to use that, please contact GSL to confirm.

Battery Management System(BMS)

Voltage Protection

Low Voltage Protection in Discharging：

When any battery cell voltage or total voltage is lower than the protection value during discharging, the over-discharging mode is activated, and the battery buzzer makes an alarm sound. Then battery system stops supplying power to the outside. When the voltage of each cell back to rated return range, the protection is over.

Over Voltage Protection in Charging：

Battery will stops charging when total voltage or any battery cell voltage reaches the rated protection value during charging stage. When total voltage or all cell back to rated range, the protection is over.

Current Protection

Over Current Protection in Charging：

When the charge current＞45A, current limit protection mode is activated, current will be limited to 5A，protection is removed after rated time delaying 10S. Circulate like this until the current is lower than 45A.

Over Current Protection in Discharging：

When the discharging current is greater than the protection value 55A, the battery buzzer alarms and the system stops discharging. Protection is removed after rated time delaying 1min.

Caution:

The buzzer sound alarm setting can be manually turned off on the background software, and the factory default is on.

Temperature Protection

Low/Over temperature protection in charging：

When battery’s temperature is beyond range of -5 ℃ ~+55 ℃ during charging, temperature protection is activated, device stops charging. The protection is over when temperature back to rated working range.

Low/Over temperature protection in discharging：

When battery’s temperature is beyond range of -20℃~+55℃ during discharging, temperature protection is activated, device stops supplying power to the outside. The protection is over when temperature back to rated working range.

Other Protection

Short Circuit Protection：

When the battery is activated from the shutdown state, if a short circuit occurs, the system starts short-circuit protection for 60 seconds.

Self-Shutdown：

When device connects no external loads and power supply and no external communication for over 72 hours, device will dormant standby automatically.

Caution

Battery’s maximum discharging current should be more than load’s maximum working current.

   After pressing the power button, if the battery status indicator on the front panel continues to be red, please refer to the “4.2 Alarm description and processing “. If the failure cannot be eliminated, please contact the dealer timely.

2. Use a voltmeter to measure whether the voltage of the circuit breaker battery access terminal is higher than 42V, and check whether the voltage polarity is consistent with the inverter input polarity. If the circuit breaker battery input terminal has a voltage output and is greater than 42V, then the battery has begun to work normally.

3. After confirming that the battery output voltage and polarity are correct, turn on the inverter, close the circuit breaker.

4. Check if the indicator of the inverter and battery connection (communication indicator and battery access status indicator) is normal. If it is normal, successfully complete the connection between the battery and the inverter. If the indicator light is abnormal, please refer to the inverter manual for the cause or contact the dealer.
