If you have a Clenergy SPH-30 inverter or similar unit it's now easy to log the data form the inverter device for storage to a microSD card or monitoring on the Internet with this next project. It's based on an Ethernet-enabled Arduino board - the EtherTen - and taps into the inverter's RS232 port to interrogate it for data. This can then be stored or broadcast to a monitoring service such as pvoutput.org (for example). It's a nifty project that allows you to keep track of solar generation versus power usage to enable more efficient energy use in the household or other area.
This is a very well documented project - even if you're not up for building one, check out the instructions from here. And for more, we're on twitter and Google+, so follow us for news and product updates as well.
As you can see from the image and project site, apart from using the Freetronics EtherTen - a protoshield was used to hold the external device interfaces and other circuitry. When doing so yourself, please consider our range of ProtoShields. From the tiny LeoStick to the Mega range, we offer a complete range for you to work with.
