Learn how to calibrate Solis IGBT current measurement systems effectively and accurately.
Calibration requires a multimeter, calibration software, and a stable power source to ensure accurate measurements.
Calibration should be performed at least once a year or whenever there are significant changes in system performance.
Inverters utilize Insulated Gate Bipolar Transistors (IGBTs) for efficient current management. The IGBT current measurement system is crucial for ensuring that the inverter accurately tracks the performance of the solar array. If the IGBT system detects anomalies, such as discrepancies in expected versus actual current output, it may trigger protective measures to prevent damage. This can be due to various factors, including improper insulation resistance (RISO) measurements, ground fault detection, or exceeding grid frequency limits.
Homeowners may observe irregular LED patterns on the inverter, indicating operational faults. The monitoring app may show alerts regarding current measurement errors or production drops, often accompanied by a significant decrease in energy output.
Always ensure that a licensed electrician or certified solar installer performs any electrical work or troubleshooting to avoid personal injury or damage to the system.
To prevent future calibration issues, regularly inspect and maintain wiring connections, ensure the inverter is kept in a stable environment to avoid temperature fluctuations, and schedule periodic firmware updates. Additionally, consider implementing insulation resistance testing to monitor the integrity of the system.
