The smartsolar will not start charging until PV voltage is 5 Volts higher than the battery voltage.

see note 1b) on this datasheet

The important data's are not on the screenshot. The daily min/max PV and battery voltage. Can you please make a screenshot of that?

Also check all fuses and switches between the MPPT and the battery. Also check the fuse that is directly installed at the MPPT.

Connection between MPPT and battery must be fine or the app wouldn't be showing the battery voltage.
