How to Install
Installing the HV20K409 high voltage stacked lithium iron phosphate battery requires careful planning and adherence to safety protocols. Below is a step-by-step guide to assist you in the installation process.
Preparation and Planning
- Review the user manual and installation guide provided with the HV20K409.
- Determine the installation location, ensuring it is well-ventilated, dry, and free from direct sunlight or extreme temperatures.
- Ensure that the installation area can support the weight of the battery.
Safety Precautions
- Turn off all power sources connected to the battery system.
- Wear safety goggles and gloves to protect against electrical hazards.
- Ensure that the installation area is free from flammable materials.
Mounting the Battery
- Place the battery pack with its base against a wall that is perpendicular to the ground (90° angle). Important: Ensure that the wall is a load-bearing wall; installation on non-load-bearing walls is not permitted.
- Attach the hanger to the battery holder. Once the hanger is in place, secure it to the wall using the holes provided in the hanger.
- Remove the battery pack from the wall. Using a hammer drill, create a Ø8mm hole with a depth of 60mm in the wall.
- Insert the M8 blasting screw into the drilled hole in the wall.
- Reposition the battery pack and align it properly. Secure it in place by tightening the nut onto the blasting screw.
- Align the pins and carefully place the second battery module on top of the first module. Secure the hanger using the provided screws. After installing the second battery pack, continue the process by sequentially installing the third and fourth battery packs. Once all battery modules are in place, proceed to install the main control box to complete the assembly.
Electrical Connections
- Open the side cover of the main control box.
- Use appropriate gauge wiring to connect the battery to the inverter or energy management system. Ensure that all connections are tight and secure.
- Connect the positive terminal of the battery to the positive input of the inverter and the negative terminal to the negative input. Follow the polarity markings to avoid short circuits.
- Once connected, securely lock the side cover to finalize the installation.
Integration with Solar Inverter
- Connect the battery to the high voltage solar inverter as per the specifications. Ensure that the solar inverter is compatible with the HV20K409’s voltage and capacity.
- If applicable, connect any communication cables between the battery and the inverter for monitoring and control.
Testing the Installation
- Before powering on the system, double-check all connections for tightness and correct polarity.
- Use a multimeter to verify that the voltage at the battery terminals matches the expected output.
- Start the high-pressure system by pressing the power switch for 3 seconds. When the red light on the switch illuminates, release your finger to activate the system.
Monitoring and Maintenance
- After installation, regularly monitor the battery’s performance through the BMS interface (if available) or any connected monitoring systems.
- Schedule periodic maintenance checks to ensure all connections remain secure and the battery operates within the specified parameters.
