Solar Panel Victron system shows a higher voltage than the VW Cali display

[BenVanMan]

I need some advice over the Victron Charger and Solar Panels. The Cali display shows voltage of 12.6 but the Victron shows 13+ (see images) - the fuses both look intact so not sure what’s going on.

The battery does seem to require charge every morning but never after that despite using the fridge etc.

Any ideas?

What is the voltage across the battery and what is the 3A draw?

You do realise the Victron voltage was in full sunlight , 14.27hrs, and the Control Panel voltage of 12.4v at 2310hrs when it is dark.
Compare the voltages at the same time of day.

3A draw was the fridge being on but now turns off the voltage is out by 0.8 on the panel compared to the Victron

The voltages are still out by 0.8 any ideas or is that normal?

You are using 2 different systems to measure the voltage.
Leave the fridge off for at least 30 minutes and then switch the Control Panel Off, bottom L button. Wait for 60 seconds and switch On again, same button.
What’s the voltage of both units, Victron and Control Panel?
