I watched the video about overloads on the multiplus II, and understand that it is very flexible with short term overloads and can handle 5550W for up to 2 mins, as well as attempt to power something for 30 cycles with huge inrush where it can't maintain its output voltage.
That's fine. And I am not worried about overloads by ordinary loads which give the inverter nice time to decide when to switch off. But the one thing that I have always feared, is starting a powerful power tool like a circular table saw with an inductive motor and no soft start, and if it can ruin the inverter. When the thing needs to start up from a peaceful idle output to a sudden huge spike, with a motor that can also draw a choppy current and introduce high voltage transients/spikes that can cause the FETs to arc, I am worried that it will blow up before the protection mechanisms can kick in. Many cheap inverters don't withstand the test and blow the FETs. Now I have a lot more confidence in a multiplus which also has an output transformer to add some kind of impedance between the FETs and the output which many cheaper inverters don't. But can I be confident that the multiplus should protect itself in most cases with "abusive loads"?
Not counting in any intentional attempt at destroying it, of course.
