The Hoymiles DDSU666 (CT-100A) single-phase electricity meter has an external current transformer and can be used to measure and display PV power supply, load consumption, or export power.

Hoymiles Smart Power Export Management

Hoymiles Smart Power Export Management is an intelligent and reliable solution for managing the amount of electricity exported to the grid. The system consists of a meter with integrated external current transformers (CTs), a Hoymiles Gateway DTU-Pro (or DTU-Pro-S), and a Hoymiles micro inverter. The current transformers included in the scope of delivery accurately measure the current flow, while the Hoymiles electricity meter communicates export or load consumption values. For an accurate representation of PV production, the meter must be installed at the output of the PV system.
