Inverter CT Current Transformer – High Accuracy CT for Solar Inverters

The Inverter CT (Current Transformer) is designed for accurate current measurement and monitoring in solar inverter, energy management, and electrical power systems. It measures AC current and provides a proportional output signal to help the inverter monitor power flow and manage energy efficiently. This Current Transformer (CT) is suitable for applications such as solar power systems, grid-tied inverters, hybrid inverters, energy meters, load monitoring, and power management systems. Its compact design allows convenient installation inside electrical distribution panels and inverter systems. The current transformer in the image has a primary current rating of 150 Amperes (150A) and a secondary current rating of 5 Amperes (5A).
