Default Inverters - again

Getting to the point where an inverter starts to make more & more sense.
Phone charger, drill chargers, light bar charger etc.

Looking at these http://www.tlc-direct.co.uk/Products/TLINV300.html

It mentions in the spec "These inverters generate a modified sine wave,
which although not perfect, is considerably superior to the square waves
which are produced by most other inverters".

Is that a good thing?


Generally yes - some things are not as happy being supplied with a
square wave (lots more harmonic noise).

It also mentions Peak power - 1000w Does that mean it would run an 800w
angle grinder for long enough to cut off a padlock or wheel clamp?


Probably not - it probably means there are enough FBC's in there to cope
with a big switch on surge. So it will get something running that draws
less than 300W normally but perhaps needs several times that to start.
Something with an induction motor like a fridge for example.
