We have seen reports of Victron Inverters not being compatible with appliances such as hair straighteners, and hair dryers on the low setting.

We can confirm this behavior on
-Victron Multiplus 12V 1600VA and
-Victron Multiplus 24V 3000VA (can be seen in the attached video).
The lack of an answer from a Victron representative so far is disappointing. I really don't know what to tell our customers. "Please bear in mind that Victron Inverters are not compatible with certain devices such as hair straighteners." or "You can continue using your hair straightener even though the inverter makes a scary noise, it won't damage the inverter." ???
Victron is the brand we currently recommend most, but unanswered issues like this erode that position.
