JosephTec has long been dedicated to developing and manufacturing meter testing equipment for Taiwan Power Company, Taiwan Electric Research & Testing Center, the Bureau of Standards, and various meter manufacturers. Our equipment is refined and professional, providing the highest level of accuracy and stability in testing solutions nationwide. It is suitable for characteristic testing of billing meters used by electric companies, including type certification, automatic calibration, automatic verification, and standard traceability.

An innovative solar energy traceability monitoring system utilizes string monitors and other monitoring components within the combiner box to trace and grasp detailed power generation data for each string and each node. This allows for pinpointing problem areas. Even in large projects, operations and maintenance remain simple and efficient.

With advanced battery series-parallel measurement technology and intelligent traceability monitoring capabilities, combined with internationally advanced PCS, our energy storage system provides secure, efficient operation and maintenance for power storage, dispatch, and integration, whether using new or old batteries, and whether for grid-connected or off-grid applications.

To ensure the long-term high performance and maintenance of photovoltaic (PV) and energy storage systems, JosephTec leverages its expertise in power and energy measurement technology to develop a variety of monitoring meters. Using equipment equivalent to standard laboratories, we implement fully automated calibration and quality control to ensure every product delivered is accurate, reliable, and cost-effective. The JosephTec String Monitor efficiently connects to the series-parallel arrays of solar modules and energy storage batteries, integrating both convergence and monitoring functions. It reliably collects and accurately measures power data for each string and circuit, providing traceable information for efficient operation and maintenance. This enables the monitoring system to pinpoint issues directly, leaving no problem hidden and ensuring prompt resolution.

To respond to domestic electricity reforms and upgrades, JosephTec represent the highly cost-effective Swiss MTE precision power measurement instruments, integrating them into our expertise in meter testing equipment and precision power monitoring systems. The MTE Group has earned a reputation for high quality and innovative solutions, becoming a global leader in the field of instrument testing. MTE's product line includes both stationary and portable instrument testing equipment systems.

STUDER of Switzerland offers reliable high-performance bidirectional inverters that combine solar energy, energy storage, and supply and load sides, forming a compact smart grid capable of grid operation during supply and automatic off-grid operation during power outages. Combined with JosephTec’s tailored BMS and EMS, this intelligent energy storage system maximizes the efficiency of battery storage and the synergistic effect of power integration, ensuring the safety and reliable operation of the system.
