Online Data Logging
You can add an off-the-shelf system that provide wireless remote monitoring of your energy system performance. These systems can be programmed to alert users or installers via email when redline parameters are exceeded.
Adding remote monitoring capability is in both the best interest of the consumer and the installer as it allows early detection of any unexpected performance issues.
And then there's the "coolness factor" of being able to monitor your system real time from any internet connected device!
This system can tally and log real time dollar savings or pounds of carbon diverted from the atmosphere if desired.
