MPPT 75/15 PWM signal problem

Hello,

Since the upgrade of the hardware to version 1.6 of the MPPT 75/15
, the duty cycle of the PWM signal is disturbed by noise (see peak in the red box), this noise comes from the VE.Direct port of the MPPT.

If we go back to an old version of the MPPT hardware (version 1.49), we do not measure noise.

As it stands, we can't filter out this spike because its appearance is completely random.

Can you tell me if this problem is known at Victron and if new hardware correcting the problem is in development?

Cordially
