Hi,
in the frame of an environmental metering project, I have programmed as a by-side product, a WiFi battery monitor function using an ESP8266 and an INA226 power monitor.
It shows the battery values as trends, calculates the energy to/from the battery by hour and day, calculates the internal resistance of the battery and roughly evaluates the DOD. All values are stored fo a year in the cloud and can be exported to a spreadsheet.
The display occurs in the cloud and can be shown on every computer/smartphone worldwide.
I could also consider to network several ESP8266's together to report the voltage/current of every single panel in a multi-panel configuration . That would need an ESP8266, an INA226, a buck converter, a small battery shield and a casing for every panel. The bill of materials would be less than 15$ per panel.
A monitoring of several batteries could also be considered using the same bill of material (excepted the battery shield).
Is that something useful?
What would you want to get?
