Щит с АВР для ИБП с гибридным инвертором

Introduction

This tutorial provides a comprehensive guide on assembling a shield with automatic voltage regulation (AVR) for an uninterruptible power supply (UPS) using a hybrid inverter. This project is particularly relevant for those interested in building solar power stations and utilizing hybrid inverters for energy management.

Step 1: Gather Required Materials

To successfully build the AVR shield for your UPS, you will need the following materials:

• Hybrid inverter (e.g., Аксіома 3000)
• Solar panels (polycrystalline or monocrystalline)
• Charge controller (PWM or MPPT)
• Battery bank (AGM or alkaline batteries)
• Electrical components for the shield (fuses, relays, wires, connectors)
• Tools (screwdriver, wire strippers, multimeter)

Step 2: Assemble the Hybrid Inverter

1. Position the Inverter: Place the inverter in a well-ventilated area, ensuring it is secure and easily accessible.
2. Connect Solar Panels:
   • Identify the input terminals on the inverter.
   • Connect the solar panels to the inverter's solar input.
   • Ensure correct polarity to avoid damage.
3. Connect the Battery Bank:
   • Attach the battery bank to the inverter's battery terminals.
   • Use appropriate gauge wires for safety and efficiency.

Step 3: Set Up the Charge Controller

1. Choose the Charge Controller Type:
   • Select between PWM or MPPT based on your solar panel configuration and energy needs.
2. Connect to Solar Panels:
   • Wire the solar panels to the charge controller’s input.
   • Follow the manufacturer's instructions for proper connections.
3. Connect to Battery Bank:
   • Wire the charge controller to the battery bank to ensure proper charging.

Step 4: Build the AVR Shield

1. Design the Shield:
   • Plan the layout for fuses, relays, and connectors on a mounting board.
   • Ensure the design accommodates all components and allows for easy access.
2. Mount Components:
   • Securely attach fuses, relays, and connectors to the board.
   • Make sure to leave space for wiring.
3. Wiring the Shield:
   • Connect wires from the inverter and battery to the appropriate terminals on the shield.
   • Use color-coded wires for clarity (e.g., red for positive, black for negative).

Step 5: Test the System

1. Power On: Turn on the hybrid inverter and check for proper operation.
2. Check Voltage Levels:
   • Use a multimeter to ensure the output voltage from the inverter matches your requirements.
   • Monitor battery charge levels to confirm proper charging from solar panels.
3. Troubleshoot: If any discrepancies arise, double-check all connections and wiring.

Conclusion

Building a shield with AVR for a UPS using a hybrid inverter is a rewarding project that enhances energy management in solar power systems. Key steps include gathering materials, assembling the hybrid inverter, setting up the charge controller, building the AVR shield, and testing the entire system. For further enhancements, consider experimenting with different battery types or expanding solar panel capacity. Always prioritize safety when working with electrical components.
