SmartSolar 75/15 SOC Calc Raspberry Pi

Good Evening Victron Community,


I have been running a tiny setup with a single SmartSolar 75/15 and a 65Ah Lead Acid battery for the past few days.

The latest addition to the setup was a RaspberryPi running VenusOS that connects to the SmartSolar 75/15.

Would it be possible in future releases to Calculate SOC of the battery (if given a Capacity in Ah) for systems where all loads pass through the MPPT load output and where all charging happens through the MPPT?

Additionally is there a way to remove the AC Input and Loads symbols for these DC only Systems?

Kind Regards

Hi Randolf


to display the SOC it must be measured first, therefor you will need the BMV7xx first which includes a shunt.

without a shunt it is mostly SOC guessing.


For the display, try using mobile home slide by swiping over home screen

Hi Ossi,


Thanks for your reply.

Is there a way to remove tiles from the Mobile Home View?

I have read that it is possible to add a custom logo.


Kind Regards
