  • Page 15: Dip Switch Definition And Description

    2.4.1 DIP switch definition and description When the batteries are connected in parallel, the master communicates with the slaves through the CAN interface. The master summarizes the information of the entire battery system and communicates with the inverter through CAN or 485.. Nota: DIP switch from (1) to (3) define different protocols and distinguish between master and slave. DIP switch (4) for Baud rate selection. • DIP switch (4) OFF: set the RS485 baud rate to 9600 and the CAN to 500k • DIP switch (4) ON: set the RS485 baud rate to 115200 and the CAN to 250k The communication cable from the master CAN IN to the inverter comm port should be the correct one. If the master is the latest B4850 battery with DIP switch. SETT. DESCRIPTION Master Set1. When the battery works with GOODWE, Solis, LUX, Sofar, DEYE, VICTRON, IMEON, Sungrow, SMA, RENAC, DELIOS, SAJ(CAN Comm), before starting the battery,you need put the master DIP switch “#3” to the “ON” position (to the top), then turn on the batteries. Master Set2. If the battery communicates with the Axpert-king/VMIII/MAX, Infinisolar, Growatt SPH/SPA(CAN comm), GMDE, turn the master DIP switch “#2” to “ON” position. Master Set3. If the battery communicates with the Growatt SPF HVM-P/ES/WPV by RS485 communication, turn the master DIP switch “#2” and “#3” to “ON”. Master Set4. If the battery communicates with the Schneider Conext Series, turn the master DIP switch “#1” and “#3” to “ON” (MASTER4) Slave Set1. When you setup the master DIP as setting 1~4, all the slaves keep the DIP 0000, no need change. Master Set5. If the battery module is in communication with the ICC by 485 communication, turn the master DIP switch “#1” and “#4” to “ON”. This is only for ICC (a special communication device of some no-communication inverter), it’s a special firmware in BMS, different from general firmware, so if customers want to use that, please contact dyness to confirm.

  • Page 18: Battery Management System (Bms)

    Battery Management System (BMS) 2.5.1 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. 2.5.2 Current Protection Over Current Protection in Charging: When the charge current >45A, current limit protection mode is activated, current will be limited to 4A, 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.

    Fig. 3.2 - Inserimento Fig. 3.3 - Iinstallazione 3.7.3 Electrical installation Before connecting the power cables, use multimeter to measure cable continuity, short circuit, confirm positive and negative, and accurately mark the cable labels. Measuring methods: • Power cable check: select the buzzer mode of multimeter and detect the both ends of the same color cable. If the buzzer calls, it means the cable is in good condition. • Short circuit judgment: choose multimeter resistor file, probe the same end of positive and negative pole, if the resistor shows infinity, means that the cable is available. • After visual testing of power line is connection, the positive and negative poles of the battery shall be connected respectively to the positive and negative poles of the opposite terminal. • It is better to add a circuit breaker between the inverter and the battery system. The selection of the circuit breaker requires: Voltage: U>60V Current: I = Inverter power / 45V Cable connection: 1. Ground cable installation 2. Battery module parallel cable installation 3. Parallel communication cable connection Nota: The BAT-INV comms cable is from inverter comm port to master CAN IN port, BAT-BAT cable is from master CAN OUT to slave1 CAN IN,slave1 CAN OUT to slave2 CAN IN.

    4.0 USE, MAINTENANCE AND TROUBLESHOOTING Battery system usage and operation instructions • After completing the electrical installation, follow these steps to start the battery system. • Refer to the description of the DIP switch of 2.3.1 to prepare the battery module before starting up, then press the ON/OFF button to the ON position, next press and hold the SW button for 3 seconds. • After the indicator self-test, the RUN indicator will light and the SOC indicator will be on (100% SOC status in the Figure 4-1). Fig. 4.1 - B4850 Caution: 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. • 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 begin to work normally. • After confirming that the battery output voltage and polarity are correct, turn on the inverter, close the circuit breaker. • 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.
