Modified Sine Wave Inverter

Main Sections
Modified Sine Wave Inverters.

When you buy an inverter you can get away with a cheaper low cost
modified sine wave type as long as you are not planing to use it on
electric motors or charge batteries and forget about it. I have read where
a modified sine wave inverter will confuse small battery chargers and they
will not stop charging. It has never happened to me because I don’t put my
laptop on charge from modified sine wave inverters for any longer then
needed to allow me to use it. If I am in a need to charge my lap top in my
automobile then I am in a hurry to use it so it is not normally charging very
long.

As said above, cheap inverters will make Electric Motors hammer or
make a hammering sound because of the squared wave form of the
modified sine wave. Unless you get a high quality brand of inverter like the
Xantrex DR series inverters you might end up with an odd wave form
which you will have troubles with clocks and bread makers. Some
modified sine wave inverters will not work with a neutral grounded or
transformer device like a desk top computer or most any power strip or
UPS. The neutral ground or transformer will put cheap inverters in to alarm
mode and cause a shut down
