1. Introduction
This manual provides detailed instructions for the installation, operation, and maintenance of your AMPINVT MPPT Solar Charge Controller. This device is designed to efficiently manage power flow from your solar panels to your battery bank, ensuring optimal charging and system performance. Please read this manual thoroughly before installation and operation to ensure safe and correct usage.
2. Safety Instructions
Adhering to these safety guidelines is crucial for preventing personal injury and damage to the equipment.
- Always connect the battery first to allow the controller to recognize the correct system voltage. Never connect the solar panel array to the controller without a battery. The disassembly sequence is contrary to the wiring order.
- DO NOT connect any inverter, wind turbine, alternator, or charger directly to the charge controller. Connect inverters directly to the battery.
- Ensure solar input voltage is higher than 3V or more than the battery's voltage, and total input power is within the specified range.
- The charging indicator may turn on and off, and the charging current may fluctuate, especially on cloudy days or in low light conditions. This is normal operation.
- If the controller buzzes, it indicates the fan is dissipating heat. This is normal.
- DO NOT install the charging controller in direct sunlight to avoid power loss due to overheating. Ensure adequate ventilation by leaving approximately 20cm of space around the controller for proper airflow.
- Ensure all connections to and from the controller are tight. DO NOT allow the positive (+) and negative (-) terminals of the battery to touch each other.
- Only qualified personnel should perform installation and maintenance.
