ABB Aurora WIM power supply

[jetronic]

Hello Renzo, a great project you have made.
I think it’s really great and would like to rebuild it.

What I wonder, why do you need a battery?
You wrote, if there is no sun, the ESP runs via battery.

Where does the ESP get the power from when the sun is shining?
You must have a 230V to 5V power supply somewhere. At the 230V you actually always have power, unless there would be a power failure.

Can you give me a hint or post a photo?

Thanks

Chris

Hi jetronic,
under my roof I have only the power from solar inverter, so if no sun no power, and I add an UPS to the device so the server It’s always online, and I prevent power noise.

The system work without that also, you must only remove the battery shield.

Bye Renzo
