Zhejiang Yongtailong Electronic Co., Ltd. (YTL) welcomed customers and industry visitors to Booth 16.3G24 on the opening day of the 140th China Import and Export Fair (Canton Fair).
This year, YTL is highlighting its Fast Data Refresh Energy Meter Series, DC Energy Meter Series and Panel Power Meter Series, introducing products for industrial electrical monitoring, solar PV, battery energy storage and other energy management applications.
During the opening-day discussions, visitors showed interest in YTL’s manufacturing capabilities, product functionality and suitability for solar and energy storage projects. Questions about detailed electrical monitoring, including harmonic analysis, provided an opportunity to introduce the capabilities of YTL’s multifunction panel meters.
Customer Discussions Focus on Manufacturing Capabilities and Product Functions
For international project buyers, selecting an energy meter involves more than comparing basic specifications.
At YTL’s Canton Fair booth, customers discussed the company’s manufacturing capabilities and the electrical measurement functions needed for their projects.
YTL’s manufacturing operations cover PCB assembly, meter assembly, programming, calibration, testing and packaging. These processes support standard energy-meter production and selected OEM/ODM projects.
Visitors interested in project cooperation can also discuss model configuration, sample evaluation, product testing, communication requirements and manufacturing preparation.

YTL96-323D: Harmonic Analysis and Detailed Electrical Monitoring
One of the technical topics raised during the exhibition was the need for more detailed power monitoring in solar PV and battery energy storage applications.
In these projects, basic kWh readings may not be sufficient. Depending on the measurement boundary, engineering teams may also need to monitor voltage, current, active and reactive power, power factor, electrical imbalance and harmonic content.
YTL’s YTL96-323D multifunction panel power meter is a product option for these requirements.
The YTL96-323D is a 96 × 96 mm three-phase panel-mounted digital power meter designed for electrical distribution and power monitoring applications.
Its documented functions include:
- 2nd–63rd voltage and current harmonic analysis for monitoring harmonic content at the selected AC measurement point
- Class 0.5S active energy accuracy for energy measurement
- Voltage, current, active/reactive power, energy and power factor measurement
- RS485 communication supporting Modbus RTU and DL/T 645-2007
- Y-Bus communication for supported external sensors
- Four digital inputs and two digital outputs
- Event alarms and sequence-of-events (SOE) recording
These functions can support the investigation of electrical operating conditions at selected distribution panels, PV inverter AC circuits, BESS power conversion system (PCS) AC boundaries and other suitable three-phase measurement points.
For solar and storage projects, harmonic information can help engineers understand the voltage and current harmonic conditions at the installed meter boundary.
However, harmonic monitoring does not replace specialist disturbance recorders, high-speed waveform instruments or formal power-quality compliance testing.
The YTL96-323D provides electrical measurements and data outputs. Final analysis, compliance assessment and any corrective control actions remain the responsibility of the relevant project and system specialists.

Fast Data Refresh Meters for Energy Monitoring Applications
YTL’s Fast Data Refresh Energy Meter Series is another key product focus at the Canton Fair.
Selected models are designed to provide electrical measurement data through communication interfaces with short response times.
These meters can be evaluated for selected applications such as:
- Solar PV monitoring
- BESS electrical measurement
- EV charging infrastructure
- Industrial energy monitoring
- Commercial power distribution
The selection of a fast-refresh meter depends on the measurement point, electrical ratings, communication interface and required data timing.
Communication response time should not be confused with internal measurement sampling rate, waveform capture capability or complete EMS control-loop response time.

DC Energy Meters for Solar and Storage Projects
YTL is also presenting its DC Energy Meter Series for projects requiring measurement at defined direct-current boundaries.
In solar PV and energy storage systems, DC-side measurement may be considered for selected battery circuits, DC power equipment or other project-defined measurement points.
Important selection factors include operating voltage, current range, sensing arrangement, energy direction and communication requirements.
DC energy measurement and AC-side harmonic monitoring serve different purposes and should be evaluated according to the project architecture.
Meet YTL at Booth 16.3G24
The Canton Fair provides YTL with an opportunity to communicate directly with customers about product selection, manufacturing requirements and electrical measurement challenges.
Whether a project involves industrial power monitoring, solar PV, battery energy storage or commercial energy management, YTL welcomes discussions about proposed metering points, electrical specifications and meter-side interfaces.
YTL focuses on the field-level electrical-measurement and data-output layer. System-level control, EMS optimisation, power-quality compliance decisions and final project acceptance remain with the responsible project parties.
YTL will continue exhibiting at the Canton Fair through October 19, 2026.
