CT sensors in solar monitoring systems track energy flow by encircling current-carrying conductors and measuring the current flowing through them. Here’s how it works:
How CT Sensors Work
- Installation: CT sensors are placed around the wires that carry electrical current from solar panels to inverters or from the inverter to the grid. These sensors do not disrupt the flow of electricity and require no modifications to the wires.
- Measurement: As the current flows through the conductors, the CT sensor outputs a proportionate voltage signal. This signal is scaled down from the detected current, ensuring safety and accuracy.
- Power Calculation: The voltage output from the CT sensor is then used to calculate the current flow. This current is multiplied by the line voltage (e.g., 230V in many countries) to determine the power consumption in watts.
- Conversion to kWh: To make this data relevant for energy billing, the power usage in watts is divided by 1000 to convert it into kilowatt-hours (kWh).
Benefits in Solar Monitoring
- Monitoring Performance: CT sensors help track the efficiency and performance of solar panels and inverters, providing insights into how much energy is generated and used.
- Compatibility with Systems: They are compatible with both residential and commercial solar systems, making them versatile for various applications.
- Easy Installation: CT sensors are compact and easy to install, making them a straightforward addition to energy monitoring systems for solar applications.
In summary, CT sensors play a crucial role in solar monitoring systems by providing non-invasive and accurate measurements of current flow, which are essential for calculating energy production and consumption.
