Project Introduction

Smart grid solar solutions are rapidly growing in complexity. Net-metering and stand-alone systems each require computers powerful enough to process data across multiple protocols while reliably managing accounting, monitoring, and control duties for DC to AC conversion; electrical generation; meters, alarms, and other I/Os; and for overall system efficiency. In addition, residential systems are now relying more and more heavily on wireless communications, such as 3G, LTE, and Wi-Fi, creating a wide demand for computing platforms with a variety of built-in wireless options. Systems integrators are usually forced to set up wireless connectivity by pairing a computer with an external module of some sort; this, however, introduces programming and reliability concerns, particularly with regard to troubleshooting and maintenance. An all-in-one wireless computer is more reliable and more economical, making it a superior solution for deployment in residential solar power systems.

Last but not least is data security: when deploying networked industrial solutions in residences, in the event that data or data security is mishandled, power companies and solutions providers could be at risk of litigation. For this reason, protecting user data is extremely important, and must be addressed with the strongest measures possible. To this end, integrating TPM into an industrially hardened system gives the strongest guarantees available against hostile intrusion.

System Requirements

• A single residential solar software package designed for diverse household networking environments and one computer that supports a variety of wireless connections, to reduce the cost of software development.

• Residential solar power systems require a space-saving system design to reduce the impact on the home owner’s daily life.

• The solar power system shares the same wireless connection used by the family to connect to the Internet, which requires a high level of security to protect the users’ personal information.

Moxa Solution

The UC-8100 provides several interfaces. With standard SIM card slots, mini-PCIe for cellular modules, and USB adapters for wireless modules, linking the UC-8100 to a wireless channel is easy, regardless of whether you’re using 3G, HSPA, GPRS/GSM, Wi-Fi, or LTE. The UC-8100 lets you configure the same little box to meet your diverse communications needs, saving both time and money.

Moxa’s UC-8100 RISC computers are perfectly designed for the small, highly optimized RISC computers sought by residential users, and deliver enough processing power to handle even the most resource-hungry applications. Measuring only 10.1 x 2.7 x 12.8 cm, the UC-8100’s extremely small dimensions provide system designers with unbeatable flexibility for managing heavy-load data processing and communications. And with built-in SD and mini SD sockets, the UC-8100 allows for easy storage expansion, delivering plenty of space at an economical cost.

Why Moxa

• Wi-Fi and cellular modules plus a programmable router, for a 3-in-1 communications device that saves on deployment and maintenance costs
• Compact size (10.1 x 2.7 x 12.8 cm) makes system design and installation an easy job
• Strong hardware-integrated TPM security plus Moxa’s patented secure boot feature together give you the strongest EAL4+ security possible
• Onboard RS-485 interface and native Modbus support allows direct connections using the most common serial protocol in the solar industry

About UC-8100 Wireless RISC Computers

Moxa’s UC-8100 RISC computer is an embedded computing platform specifically designed for large scale, big data WAN computing solutions.
