Voltage Protection

• Low Voltage Protection in Charging: When cell or total voltage falls below the rated protection value during discharging, over-discharging protection activates, and power supply stops. Protection releases when cell voltage returns to the rated range.
• Over Voltage Protection in Charging: During charging, charging stops when total voltage exceeds the rated value or any single cell voltage reaches the protection value. Protection is released when total voltage or all cells return to the rated range.

Current Protection

• Over Current Protection in Charging: If charging current exceeds the trigger value for 15 seconds, charging overcurrent protection activates, entering fault mode. Charging input and discharging output are disabled, displaying fault code C05. Fault clears automatically after 1 minute. After 10 occurrences, manual restart is required.
• Over Current Protection in Discharging: If discharging current exceeds the trigger value for 15 seconds, discharging overcurrent protection activates, entering fault mode. Charging input and discharging output are disabled, displaying fault code C06. Fault clears automatically after 1 minute. After 10 occurrences, manual restart is required.

4. Installation and Configuration

4.1 Preparations for Installation

4.1.1 Safety Requirement

Installation must be performed by trained personnel with adequate knowledge of power supply systems. Adhere to safety guidelines and applicable local standards.

• Circuits below 48V must comply with SELV requirements (IEC60950).
• When working inside the cabinet, ensure the system is powered down and all battery devices are switched off.
• Arrange distribution cables systematically with protective measures to prevent accidental contact.

4.1.2 Installation Environment

• Working temperature: -20°C to +55°C
• Charging temperature range: 0°C to +55°C
• Discharging temperature range: -20°C to +55°C
• Storage temperature: 0°C to +35°C
• Relative humidity: 5% to 95%
• Elevation: ≤ 2000m
• Operating environment: Suitable for indoor installation, shielded from direct sunlight, wind, conductive dust, and corrosive gases.
• Ensure the installation site is distant from the sea to prevent saltwater and high humidity exposure.
• The ground must be flat and level.
• The site should be free of flammable or explosive materials.
• Optimal ambient temperature: 20°C to 30°C.
• Avoid areas with excessive dust or clutter.

4.1.3 Tools

4.2 Unpacking Inspection

• Upon arrival, follow established rules for loading/unloading to prevent exposure to sunlight and rain.
• Before unpacking, verify package count against the shipping list and inspect outer cases for damage. After unpacking, check for loose/damaged wiring, contacts, cracks, deformations, or leaks. Replace damaged batteries immediately. Do not charge or use damaged batteries. Avoid contact with liquid from a ruptured battery.
• Handle components with care to protect surface coating.

4.3 Installation Procedure

4.3.1 Mounting the Battery

(a) Wall-Mounted method

Step 1: Using wall-mounted components, fix them to the wall. Drill 4 holes (10mm diameter, 50mm depth) using a 10mm drill bit.

Diagram showing drilling dimensions for wall mounting.

Step 2: Lift the machine onto the wall-mounted components and secure it with one M4*12 screw on each side.

Diagram showing securing the unit with screws.

(b) Floor-Mounted method

Diagrams showing floor-mounting clearances (≥300mm) and two-row installation on the ground.

4.3.2 Batteries in parallel

The LPBF24200-A series supports parallel connection for expansion. Connect batteries as shown in Figure 1. It is recommended to use a battery pack combiner box (BTCB0606/BTCB0303) or confluence copper bar.

4.3.3 Series connection is not allowed

1. Batteries can be connected in parallel only. Series connection is not allowed. Use in an upright position only.

2. Batteries are not allowed to be connected with PWM controllers for charging. Special Attention: Due to the built-in protection board, the battery pack has over-discharge protection. It is strongly recommended to stop using the load when the battery pack is over-discharged. The battery pack cannot be repeatedly activated for discharge. It may fail to be activated by AC or PV activation cables (requiring a special charging activation method) and thus cannot be charged. Therefore, when the battery pack is low power, charge it as soon as possible when main power or solar energy is available.

6.2 Maintenance Troubleshooting

6.2.1 Analysis and Treatment of Common Faults

7. Battery recovery

Aluminum, copper, lithium, iron, and other metal materials are extracted from discarded LiFePO4 batteries using an advanced hydrometallurgical process, achieving up to 80% recovery efficiency.

7.1 Recovery process and steps of cathode materials

Aluminum foil (collector) is dissolved in NaOH alkaline solution, forming NaAlO₂. After filtration, filtrate is neutralized with sulfuric acid, precipitating Al(OH)₃. When pH > 9.0, aluminum precipitates. Filter residue is treated with sulfuric acid and hydrogen peroxide, dissolving lithium iron phosphate into Fe₂(SO₄)₃ and Li₂SO₄, separating from carbon black. Filtrate pH is adjusted with NaOH and ammonia solution. Iron precipitates as Fe(OH)₃, followed by precipitation of the remaining solution using saturated Na₂CO₃ at 90°C.

7.2 Recovery of anode materials

Anode material recovery is straightforward. Copper purity exceeds 99% after separating anode plates, suitable for refining into electrolytic copper.

7.3 Recovery of diaphragm

The diaphragm material is primarily non-hazardous and has no recycling value.

7.4 List of recycling equipment

Automatic dismantling machine, pulverizers, wet gold pool, etc.
