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

Hoymiles Smart Power Export Management

The Hoymiles Smart Power Export Management is an intelligent and reliable solution for managing the amount of power 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 included current transformers precisely capture the current flow while the Hoymiles 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.
