In 2020, in order to better meet the new requirements of load identification, terminal block temperature measurement and harmonic metering in the draft national network standard, the three-phase metering SOC RN2026A is upgraded to RN2026B, and the single-phase metering SOC RN2025A is upgraded to RN2025B, adding waveform DMA function and power quality acceleration module.

In 2021, RN2025B RN2026B mass production.

In 2019, the world's first three-phase metering SOC RN2026A with three-phase metering error online monitoring was launched.

In 2018, RN2025A, the world's first metering SOC with online monitoring of single-phase metering errors, was launched.

In 2017, RuiNeng Micro launched the next-generation single-phase and three-phase metering core project and started to study the online monitoring technology of electricity meter metering error and developed the successful metering error online monitoring prototype.

At the beginning of 2013, Renergy Micro launched the industry's first metrology SOC with 32-bit CPU core ARM M0, the RN821X series

In 2009, when the national grid implemented the unified bidding for smart meters, the company launched the single-phase metering chip RN8209, which complied with the technical standard and quickly gained the leading position in the market, breaking the situation that the electric energy metering chip had been occupied by foreign manufacturers for a long time.
