Data Acquisition System for Smart Cloud Solar Monitoring Solutions

Energy Management System / API Optimization

Background and Challenges

A well-known brand manufacturer spanning optoelectronics and green energy chose Promate Solutions to develop their next-generation data acquisition system for its smart solar energy monitoring solution that performs energy generation status and event monitoring.

The previous generation of their data acquisition system could no longer meet the new industry performance requirements. The capacity of the microprocessor in use had been reached hence the platform could no longer support Taipower’s “Distribution Grade Renewable Energy Management System (DREAMS)” certification standard.

Like most of the data acquisition system on the market, its previous generation was not equipped with lightning and surge protection. This resulted in high rates of field failure. Subsequent exposure of damaged units to further lightning or surge can result in damage to the solar panel system. Top on the requirement list for the next-generation data acquisition system is having built in lightning and surge protection up to 4000 Volts.

  • Fully system compatibility with more than 200 inverter models on the market
  • Support OTA (Over The Air) remote firmware update
  • IEC 62368 / BSMI CNS14336-1 safety certificate
  • RS-485 gate passed IEC 61000-4-2 (Level-4) Electrostatic Withstand (ESD) test
  • RS-485 gate passes IEC 61000-4-4 (Level-4) fast pulse electromagnetic withstand (EFT) test
  • RS-485 gate passed IEC 61000-4-5 (Level-4) lightning surge withstand (Surge) test
  • Support operating temperature up to 0 – 60C (commercial) and 0 – 70C (industrial)
