FoxESS DTSU666 Energy Meter Three-Phase with CT for R Series Inverters
Measuring kit based on the three-phase FoxESS DTSU666 meter (manufactured by CHINT) intended for FoxESS R Series inverters, the commercial scale three-phase string inverters. The meter is installed on a 35 mm DIN rail in the grid connection panel and is paired with current transformers (CTs), which are necessary because the currents involved exceed the range of direct measurement.
The device measures the energy, power, voltage and current of the three phases bidirectionally and communicates with the inverter over RS485 Modbus. It is the element that allows the control of the energy fed into the grid (limitation of the exported power or zero export) and the monitoring of the system's energy flows at the delivery point.
Key features
Dedicated to R Series invertersMeasuring kit specified by FoxESS for the three-phase R Series string inverters in commercial applications.
Indirect measurement with CTsThe use of current transformers makes it possible to measure currents far higher than those of direct measurement.
Three-phase bidirectional measurementCounts the energy drawn and the energy fed in on the three phases separately.
RS485 ModbusSerial communication at 9600 baud towards the inverter for real time power regulation.
Control of the energy fed into the gridMakes it possible to limit or zero the exported power according to the network operator's requirements.
Accuracy class 1Error within ±0.5% on voltage and within ±1% on current, power and energy.
