SmartSolar MPPT firmware downgrade

We have four SmartSolar 75/15, each with an MPPT control display. Recently after updating to the latest firmware (1.61), the MPPT CONTROL now scolls UNSUPPORTED DEVICE (or something similar).

Is there a way to update the firmware of the MPPT CONTROL? Or downgrade the firmware of the SmartSolar MPPT to the previous version? When we select MANUAL UPDATE on the MPPT it only shows, "This is the latest version!"

Hi @PaulMAZOcean

Can you share a VictronConnect screen shot of the Product Info page of the SmartSolar?

And what is the firmware version of the MPPT Controls? It is available as setting number 20 on the MPPT Control.

Kind regards,
