When you put solar panels on your roof, you surely want to know all about their solarr power production. With the German SMA that is very easy to implement. Wireless. The Sunny Webbox Bluetooth communicates by Bluetooth with the inverter and so transmits all the data and saves them in a flash-memory chip.
You just install the SMA-software on your computer and so you may follow on an hourly basis the revenues of your solar system. One webbox may connect to maximum 50 inverters.
You may also choose the option of the Dutch Solar-Projects-system: zonneopbrengst.nl. So very simple a child could use it. Solar-Projects just offers a complete system. LCD panel included. So you can see for yourself what the solar panels on your roof did produce, how many trees were saved and how many FTE's/jobs were saved by using solar power.
