Merci !

This solution comes to me as called. Thank you for your contribution!

Hi Mark and thanks for your comment. My Data Logger is not the best solution to monitor the energy harvested with a PV installation because it creates relatively high energy losses. To have accurate values and low self-consumption use a current sensor according to the maximum power levels of your installation and a voltage divider.I have never worked with displays but it should not be a problem to add it to the circuit and modify the Arduino code. Take a look at the this Arduino Energy Meter www.instructables.com/id/ARDUINO-ENERGY-METER/. I think it can suit your needs after little modification.Monitoring the state of charge (SOC) of your battery is not simple. There are many good articles on the web describing different methods, more or less accurate and sophisticated. If you want to p...

If you want to protect your batteries against overcharge or deep discharge, the easiest way is to monitor the battery voltage.Please share your work as instructable.

Wouldn't it be better to use an other power supply (battery) to be able to put the module in the shade on the east side of a building to have more accurate temperature values?

Many thanks, I need to adapt the diameter to the jam jar I want to use.

Hi lomo85, Good job ! Please attach the fusion 360 file to your Instructable.

Many thanks!

Thanks JON-A-TRON. The pieces are flat and fit very well, without adjusting the offset. Amazing to see how crystal clear the edges are.

Merci !
