Heliotronics Inc. has released the SunLoggerR revenue-grade residential PV data monitoring system. With the system, homeowners can check the status of their solar array online with a personal Web portal.
The system takes recent commoditization of data acquisition hardware, a simple, appealing new Web-based display and leverages Heliotronics' mature data server back end to provide a reliable, powerful and economical turnkey package, the company says. The SunLoggerR is ideally suited for systems feeding a 120/240VAC electrical service typical of residential sites.
Features include an ANSI C12.2 kWhr meter with accuracy class 0.5, a personal Web page for the homeowner and 10 years of monitoring service. Industry firsts include a data logger with 20 years of non-volatile on-site data storage and data caching measured in decades rather than the industry standard of one month, the company adds.
