Question & Answer
Q&A about the Haier Smart Cube electricity meter
What are the Haier Smart Cube electricity meters HMT-CT120A and HMT-CT300A?
These are 3-phase power sensors with current transformers (CTs) that precisely measure energy flows and provide real-time data.
What is the difference between the two models?
Both electricity meters operate with a measurement accuracy of ±1%, thus enabling a reliable and transparent energy balance.
Which measurements are recorded?
Voltage, frequency, current, power, power factor as well as active and reactive energy are measured – for import and export flows respectively.
How quickly does the data update?
The data update rate is 100 ms. Two pulse outputs are also available for further processing.
How is the display and communication carried out?
An LCD display shows the most important values directly. Data can be transmitted to external systems and remotely monitored via the RS485 interface.
What protective functions and operating conditions are there?
With IP51 protection, a wide temperature range of -30 °C to +60 °C and 0–90% humidity, the devices are robust and durable.
For which areas of application are the models suitable?
The HMT-CT120A is ideal for smaller PV systems or households. The HMT-CT300A is suitable for larger solar systems and commercial applications.
