It is going to be a DIY project.
Measurements and logging (in a .csv file for viewing in excel or any other program) of the following (these are
- Battery Temperature using LM35
- Current using AC712 or a Clamp-on hall effect current sensor.
on a SD card or over a wifi network on a PC.
And if possible the following
- Battery Voltage
- PV Voltage
- PV current
- UPS Current using Clamp-on hall effect current sensor (for both directions)
Logging of following
Power in WH
Energy used in KWh ( CC charging current +/- UPS charging/discharging)
Plotting graphs like the example shown
Personally I'm inclined towards using ardunio uno, but I can use other hardware if all the necessary help is available.
Yes this is an over-ambitious project, but atleast I need to measure the current and temperature.
So please post your suggestions and comments.
