Introduction
Project Introduction

The exigency of rising fuel costs and global warming have led to rapid growth in worldwide demand for renewable energy. People are looking for feasible energy alternatives and solar energy is a promising solution. Ensuring that the system can be remotely monitored, managed, and controlled over the Internet is critical. A leading company in the USA needed an embedded computing solution to provide critical monitoring and reporting services for a solar energy application.

Application Requirements

  • Front-end communication computer for remote monitoring, data acquisition, data logging, and protocol conversion
  • Compact form factor for easy installation
  • Wide operating temperature range for harsh environments
  • Data logger with multiple connections for data communication
  • Real-time, web-based communication to monitor the solar array performance, battery load, and energy generated/saved
  • Design that ensures a longer MTBF to enhance system reliability
  • AI/O, DI/O module board for environmental sensor devices


Moxa Solution

To ensure that the solar energy system can be remotely monitored, managed and controlled over the Ethernet, Fat Spaniel Technologies decided to use Moxa's UC-7110 embedded computers to construct the entire system. The UC-7110 functions as a front-end communication computer to connect the PV inverter, AI and counter input module, and power meter. It is also used for remote monitoring, data acquisition, data logging, and protocol conversion.
