FoxESS DTSU666 Energy Meter Three-Phase with CT for C&I Systems
Measuring kit for commercial and industrial (C&I) systems based on the three-phase FoxESS DTSU666 meter manufactured by CHINT, complete with current transformers (CTs) sized for large loads. The meter is mounted on a 35 mm DIN rail in the main panel, while the CTs are installed on the phase conductors at the grid connection point.
The system measures the energy, power, voltage and current of the three phases bidirectionally and sends the data to the inverter or to the supervision system over RS485 with Modbus protocol. On large scale systems it is the device that enables the control of the energy fed into the grid (power limitation / zero export) and the monitoring of the company's self-consumption.
Key features
Designed for C&I systemsMeasuring configuration intended for large scale commercial and industrial photovoltaic systems.
Indirect measurement with CTsThe current transformers supplied make it possible to measure the high currents of industrial loads.
Three-phase bidirectional measurementRecords the energy drawn from the grid and the energy fed in by the system separately.
RS485 ModbusSerial interface at 9600 baud for connection to inverters and supervision systems.
Limitation of the exported powerProvides the inverter with the real time measurement needed to comply with the grid export limits.
Accuracy class 1Error within ±0.5% on voltage and within ±1% on current, power and energy.
