Autonomous Solar Station

The WindNerd One can be set up as an autonomous solar station to monitor the wind at a remote spot, provided there is mobile network coverage. Below is a reference installation, which can be adapted based on the solar components you can easily source locally.

All components to build a solar powered wind station connecting with 4G

The smartphone is powered via the USB port on the charge controller, while the anemometer is powered from the 12V battery. The smartphone should have mobile data enabled and be set to hotspot mode to share its internet connection with the anemometer. Alternatively, a 4G router powered from the 12V battery can also be used to provide the internet connection.

Estimated data usage is around 500MB per month.
