VICTRON SMARTSOLAR MPPT 250/70-MC4

On the VICTRON SMARTSOLAR MPPT 250/70-MC4, the blue light next to "Bulk" flashes slowly.

In the Ve connect app, PV Solar shows 0.00. But measured, from the solar panels come in 156V, which is not stored in the battery.

On the CCGX, the MPPT state is off.

What could be the reason why MPPT doesn't turn on?

Also check the polarity of you PV wires.

Connections checked, all correct.

Maybe some settings are missing?

Is the remote cable/plug in?

The MPPT is connected via VEDirect to the CCGX. And via VE.CAN to the battery.

I actually meant the little connector with the cable bridge in it (bottom side, on the right)

We also have this cable, but I'm not sure if he's needed in our case.
