Huawei DTSU666-H Three Phase Energy Meter with 3x 250A CT

Huawei DTSU666-H Three Phase Energy Meter with 3x 250A CT is an energy meter from Huawei, rated at 250 A, three phase.

An energy meter measures what is crossing a point in the installation and reports it to the inverter or monitoring platform over Modbus. It is the component that turns a solar system from something that generates into something that can be controlled: export limitation, time-of-use battery charging and accurate consumption monitoring all depend on a meter reading the right point in the circuit.

Meters are either direct-connected, with the supply passing through the meter itself, or CT-connected, where current transformers do the measuring and the meter reads them. Which one a job needs is decided by the size of the supply and how much of the installation can be taken apart.
