Commercial Smart Energy Meter OEM Manufacturing for Building Energy Monitoring
High-precision multi-phase energy meter OEM manufacturing with IoT connectivity and seamless integration for commercial building energy management systems.
One of our European clients has developed a sophisticated cloud-based energy management platform, but their previous energy meter contract manufacturer struggled to meet the high quality standards and lacked expertise in communication modules. So, the client turned to MOKO Technology, who can not only provide reliable hardware but also understand the complexities of IoT integration. Their goal is to get highly precise multi-phase energy meters with consistent calibration and MID certification, so their complete solution can be successfully implemented in the EU market.
Project Requirements
- Multi-phase metering capability: 3-phase, 4-wire configuration for commercial buildings
- High accuracy: The measurement error of the meter should be controlled within±0.5%
- IoT connectivity: Both BLE and LoRaWAN built-in to enable local and long-range connections respectively
- Compact design: DIN-rail mountable form factor for easy installation
- Certifications: Adherence to CE, MID and IEC 62053 regulations.
MOKO Technology's Commercial Smart Energy Meter OEM

Design & Engineering Phase
- We worked with the engineering team of the client closely to optimize the circuit design.
- The firmware was tailored to integrated with the client’s cloud platform well.
- The prototype produced before mass production ensured that the performance, functionality and overall quality were tested.
- The thermal analysis was performed to provide reliability and long-term stability of electrical cabinets.
Manufacturing Capabilities Deployed
- Bare PCB Manufacturing: Produced premium multi-layer boards
- PCB Assembly: Accurately assembled 8-layers HDI boards with 0.4 mm pitch component

Client Testimonial:
“MOKO Technology assisted us in addressing our meter accuracy and reliability problems completely. They had the insight into what was required for commercial energy meters and took us through the MID certification process without any issues. Their PCBA quality remained consistent even when producing in large quantities, which gave us the confidence to expand into new markets”. — VP of Product Development
