Tools

The following tools will be required to install the BMS BOX and the battery.

Installation Steps

Step 1: Place the front bracket and back bracket as shown below.

Step 2: Insert the battery module into the bracket from the front horizontally, and tighten the four screws on the side.

Step 3: Locate the brackets for the second battery on top of the first pair of the bracket and fasten the connecting button on the side.

Step 4: Insert the battery module into the bracket from the front horizontally, and tighten the four screws on the side.

Step 5: Connect the inverter as shown in the figure below.

Note: If the Battery modules are more than 4 pieces, please separate them into multiple stacks. Please make sure each stack only includes max. 1 BMS and 4 battery modules.

Note: For another installation, please refer to the All-In-One user manual.

Wiring Steps

A. Battery power cable
Step 1: Connect the power cable starting from the first battery module in series with other battery modules (Orange opposite, black negative). A ‘click’ sound indicates the connections are secured. The positive and negative connection of the battery cable is shown below.

Step 2: Measure voltage value: After all battery modules are connected in series, use a multimeter to measure the DC voltage on the DC terminal. The total voltage should be N *52±10V (N is the total number of battery modules). Please refer to the picture below for the voltage test.

B. Communication cable connection:
Step 1: Take the main positive cable (two orange plugs), the main negative line (two black plugs) to connect the BMS BOX.
Step 2: Then connect the 485 on the BMS BOX to the RS485-1 of the first battery module, connect the RS485-1 of the previous battery module to RS485-2 of the next battery module, leave the last module’s RS485-2 vacant. Wiring shall be connected in the sequence as shown below.

C. Grounding cable:
Connect the grounding cable to ensure that all batteries are grounded. Wiring shall be connected in the sequence as shown below.

System Startup

• When the grid-connected system is started, the inverter should be turned on first to avoid the current pulse of the inverter increasing to the battery pack.
• All installation and operation must comply with local electrical standards.
• Check all power cables and communication cables carefully.

1. Turn on the POWER switch
   • Before starting, please dial DIP to the correct position. DIP represents the number of HV2600 in the system. Please refer to the following table for details: DIP position|

The number of HV2600

---|---
0| 2
1| 3
2| 4
3| 5
4| 6
5| 7
6| 8

• Turn on the DC switch and press the POWER switch, all the lights will light up, and the green and red LED on the HV2600 module will light up for 1s at the same time, you will hear the sound of closing and cutting off the relay in BMS BOX to prove that the system works normally.

2. Module address assignment
   If the system is powered on for the first time, BMS will automatically assign the module address of HV2600 without manual configuration.

Commissioning

There are two LED indicators on the front of the battery packs to show its operating status.

• There are no warranties-implied or express-other than those stipulated herein. Fox shall not be liable for any consequential or indirect damages arising or in connection with the product specification, battery, or pack.

Troubleshooting and Maintenance

Maintenance

A. Regularly check whether the service environment of the battery meets the requirements, and the installation position should be far away from the heat source.
B. In case of one of the following situations, it needs to be charged in time:
– The battery is often undercharged;
– The battery has been out of the use or stored for more than 3 months.
C. Regularly check whether the battery and its supporting terminals, connecting cables, and indicator lights are normal.

Troubleshooting

When the red / green LED on the panel is flashing or normally on, it does not mean that the HV2600 is abnormal, it may be just an alarm or protection. Please check the ‘LED status indicators’ in chapter 7 for the detailed faulty definition before any trouble-shooting steps. In general, the alarm indication is normal without manual intervention. When the alarm triggering state is removed, HV2600 will automatically return to normal use.
– Problem determination based on the following points

1. Whether the green light on the power switch is on;
2. Whether the buzzer in BMS box on;
3. Whether the battery system can be communicated with inverter;
4. Whether the battery can be output voltage or not.

– Preliminary determination steps
The battery system cannot work, when DC switches on and POWER on, the LED doesn’t light up or flash, please consider contacting the local distributor.

1. The LED display of BMS-BOX and HV2600 is normal, but it cannot charge and discharge. Observe the display screen of the inverter and there is no SOC. Please check whether the CAN communication between BMS-BOX to the inverter is well connected. If the connection is good, please replace a CAN communication cable. If the SOC is still not visible on the inverter display screen, please contact the local distributor.
2. After the battery system is powered on if you can see the alarm information on the LED and inverter display screen at the same time, please contact the local distributor.
