How to Use

Important: Installation, commissioning, maintenance, and electrical connections must be performed by qualified professional technicians. Carefully read the complete user manual before installation and operation.

Step 1: Inspect the Battery and Package Contents

Before installation:

1. Inspect the packaging for damage.
2. Confirm that all listed package components are included.
3. Examine the battery enclosure for deformation, damage, or loose components.
4. Check the terminals and communication connections for dirt, moisture, or corrosion.
5. Inspect the power and communication cables for damaged insulation or loose connections.

Do not proceed if the battery or its components show signs of damage.

Step 2: Prepare the Installation Location

• Select a clean, stable, and dry installation area.
• The battery must be installed indoors or within a professional rain shelter.
• The installation surface must meet the equipment's weight-bearing and fire-safety requirements.
• Provide adequate space for ventilation, heat dissipation, maintenance, and safe operation.
• Keep the battery away from flammable materials, corrosive substances, heat sources, and direct sunlight.

Step 3: Position and Secure the Battery

• A qualified technician must install the battery in accordance with the manufacturer's confirmed orientation requirements.
• For rack installations, ensure the supporting structure is suitable for the battery enclosure and installation environment.
• Verify that the battery is stable and securely positioned before making electrical connections.

Step 4: Complete the Grounding Connection

Each battery enclosure includes a grounding point.

A qualified technician must:

1. Connect the battery enclosure to the grounding network.
2. Use the designated M5 grounding point.
3. Apply the specified tightening torque of 3.5 N·m.
4. Verify the required grounding resistance.

For rack installations, connect the rack to the grounding grid before grounding the individual battery enclosures to the rack.

Step 5: Connect the Power Cables

• Before making electrical connections, ensure the equipment switches are in the OFF position.
• The installer must verify electrical safety and grounding before working with terminals or conductors.
• Connect the battery's negative power terminal (P-) to the corresponding inverter negative terminal.
• Connect the positive power terminal (P+) to the corresponding inverter positive terminal.
• Confirm that connector colors and terminal polarities match.

Step 6: Connect the Communication Cable

• Select the appropriate CAN or RS485 communication interface for the compatible inverter.
• Connect the battery and inverter communication ports using the appropriate communication cable.
• Verify that the communication pin assignments match the inverter's requirements.

Step 7: Configure Multiple Batteries if Applicable

When connecting multiple battery packs in parallel:

1. Position the battery packs with at least 10 cm of clearance between adjacent enclosures.
2. Connect the parallel power cables using the applicable wiring configuration.
3. Connect the parallel communication interfaces according to the system design.
4. Confirm the correct master-and-slave configuration.
5. Do not exceed 15 battery packs connected in parallel.

For systems with a maximum current exceeding 100A, the installation manual requires a busbar connection arrangement.

Do not connect battery packs in series.

Step 8: Perform the Post-Installation Inspection

Before startup, the technician must confirm:

1. The installation environment is suitable.
2. The battery enclosure is undamaged.
3. The equipment is securely installed.
4. The power and communication cables are correctly connected.
5. Grounding connections are secure.
6. Electrical protection and insulation requirements have been satisfied.

Step 9: Power On the Battery

For single-battery operation:

1. Confirm that the battery-to-inverter wiring connections are correct.
2. Press the power button on the front panel.
3. Observe the LED indicators as they illuminate sequentially.
4. Confirm that the battery displays normal operating status.

For multiple batteries connected in parallel, power on the master battery first, followed by the slave batteries in the sequence specified in the user manual.

Step 10: Monitor Battery Status

Use the battery's monitoring interface to check:

• State of charge (SOC)
• State of health (SOH)
• Battery voltage
• Battery current
• Battery capacity
• Operating temperature
• Alarm information
• Protection status

The battery also supports monitoring through Bluetooth and Wi-Fi using the applicable mobile application.

Step 11: Use Bluetooth or Wi-Fi Monitoring
