Consumption CTs monitor what in a PV system?

Consumption CTs are used to measure the amount of electricity the home is actually using. A current transformer is clamped around the main feed to sense the AC current drawn by all the house loads and send a small signal to the inverter or monitor. By knowing the real-time household load, the system can compare it with solar production to determine how much energy is being consumed versus produced, which helps assess self-consumption and net export. This is different from a PV production CT, which tracks solar generation, or a grid-export CT, which tracks energy sent back to the grid. The purpose of the consumption CT is specifically to quantify the home's energy use.
