The vast majority of stuff will work fine, most especially if your
inverter is oversized.
Thus, a 3 kW cheap inverter will usually drive anything with loads of
500W or so.
At peak powers, the inverter waveforms are not so clean.
Usually, peak startup power needs are 3-10x actual load, for short
amounts of time.
E.g. a welder will work fine, if the welder is 2 kW and the inverter is
4 kW.
If the inverter is 2 kW and the welder is 2 kw, the welders tend to die.
Happened te me - bought a bigger welder.
