Inverter CT Current Transformer – High Accuracy CT for Solar Inverters

Description

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). Key Features Product Type: Inverter Current Transformer (CT) Application: Solar Inverter & Energy Monitoring Systems Function: Accurate AC Current Measurement Installation: Suitable for Electrical Panels & Inverter Systems Usage: Power Monitoring, Load Monitoring & Energy Management Design: Compact and Easy to Install Compatibility: Suitable for Compatible Solar & Hybrid Inverter Systems Type: ATM-24 (A common designation for a split-core type current transformer with a 24mm internal window opening). Ratio (Primary): 150/5 — This indicates a transforming ratio where a maximum primary line current of 150A scales down proportionally to a 5A current output on the secondary terminal wires for safe energy measurement. Terminal Wiring: Red (S1) corresponds to the positive/start secondary terminal, and Black (S2) corresponds to the negative/return terminal. The P1 $rightarrow$ P2 arrow indicator marks the required direction of the primary main current flow through the sensor clamp window.
