Success story – Overview
Inverters in the technical room (SMA Solar)
PV panels on the roof of the barn
Application Prodution of solar energy in a farm near Nantes, France.
Inverters are located in the technical room which is located in one corner of the barn.

Success story – Benefits
A 300 m long trench between the PV panels and the inverters has been avoided.
No need to request to local authorities to close the road during the works.
The 2 modems have been installed in 10 minutes only: 1 unit connected to the RS485 bus of the inverters in the technical room,
1 unit connected to the data logger in the farmer’s house.
The farmer can have access to data of his PV station through internet.
