The DDSU666-H is Huawei's single-phase smart meter for photovoltaic systems: it measures current, voltage, power and energy with an LCD display, communicates via Modbus-RTU RS485 with SUN2000 inverters and mounts on a DIN35 rail.

The DTSU666-H is Huawei's three-phase smart power sensor: it measures current, voltage, power and energy with class 1 accuracy, an LCD display, Modbus-RTU RS485 communication and DIN35 rail mounting. For monitoring production and consumption with SUN2000 inverters.

Huawei Smart Meter for three-phase installations - up to 80A if mounted in direct insertion - > 80A if mounted with external CTs - CTs not included
