Hello All, very confused. Victron I.T 3600w 115/230v on a boat connected to shorepower. Very happy and (almost) quitly doing its thing until i plug in the electrical heating blanket. The buzzing is too much and changes with the setting of the heating from low = annoying to high = unbearable. The blanket is an Inventum HN1312V with a draw of 60w. Very curious why this is and if there is a way to still be warm at night and being able to sleep.
