Victron SmartSolar 75/15 and small output wattage

Hello,

I just bought a Victron Smartsolar 75/15 that is connected to a small 20w panel. I also have a small 7Ah battery and run a Raspbery Pi Zero 24 hours a day.

The consumption of the raspberry pi is between 0.6W and 1 W and it works correctly connected to the Victron output, but in the application it always shows me "Current 0.0A, Power 0W". Occasionally switches to 1W for a second, but in the history it shows 0Wh consumption.

Is the output too low for the application to show consumption data? Is there any way to make it more sensitive so I can see real consumption data?

Is this figure at battery voltages? Or at RasPi voltages?

Is there any difference?

W = A * V

At battery voltage 12V, A = 0.05A/0.08A

After the conversion to 5V, A = 0.12A/0.2A

Both 0.6W to 1W.

I am expecting to see in the application a load output of 0.05 or a little more but it is always 0.00.

You are correct.
