Fox ESS CT Clamp - compatible with AC, HY & AIO ranges

FE-AIO-C | Split-core current transformer for export limitation and consumption monitoring on Fox ESS AC, Hybrid and AIO inverters.

Key Features

• 100A / 33.33mA split-core CT clamp (CTA016 specification).
• Compatible with Fox ESS AC chargers, hybrid inverters and AIO storage systems.
• Activates export limitation functionality to prevent grid export.
• Secondary CT option for tracking additional generation sources (wind, hydro, extra PV arrays).
• Simple clip-on installation - no need to disconnect live conductors.
• Non-invasive monitoring of single-phase AC current at consumer unit or supply position.

Function & Application

This CT clamp installs around the main live conductor to measure real-time import/export current, feeding data to the Fox ESS inverter for precise export control and energy monitoring. Essential accessory for zero-export installations and systems requiring accurate consumption tracking.
