12V to 230V Converter for Motorhome: Selecting Right Inverter for Blender & Rotary Washer

Hello, I need to use devices in my motorhome: a blender and a small rotary washing machine. Both devices 230v. Currently, I have a modified sine inverter but I have not connected the above devices to it.
I have a question about the converter what is needed for these devices, because I have heard that some motors can work on a modified sine wave, and others not, but what and what it depends on, I do not know ...

First of all, give the power of devices you want to connect to the inverter, battery capacity and, among others, the power of the current inverter.

and how will this affect the sine wave I need?

I do not ask about the power of the converter or the thickness of the cables or the capacity of the batteries,
I am only interested in which type of motors I can handle the inverter with sine mod. and for what you need full sine.

Hello,
the modified sine can operate:
- laptop, computer (without active pfc in the power supply)
- power tools (e.g. angle grinder, drill) - that is, all commutator motors (speed regulators may not work properly, but they must not)
- energy saving light bulbs

Induction motors (e.g. water pumps, air conditioners, refrigerators) have a problem with work, will rumble and growl (it's about higher harmonics, such a charm of induction motors)

Therefore, if the blender has a commutator motor, there will be no problem, and the washing machine has an induction motor, it is better to use a pure / full sine converter.
Of course, you can not exceed the rated power of the inverter - there must be a spare.

thanks for the comprehensive information, that's what I meant,
best regards
