I am involved in a project using the output of a small DC hydroelectric plant 
and a couple of solar panels to power a residence in rural New Mexico.  We
currently have an inverter which produces a modified sine wave output, ie.,
positive and negative pulses to run the household appliances.  Since the power
plant will be expanded in the future along with the inverter, we are con-
sidering the kind of inverter to use.  We will have electronic equipment, such
as computers, faxes, VCR, along with the ususal household appliances on this
system.  

Does anyone know of any long term effects of using such an inverter, rather
one which produces a real sine wave, such as might be obtained with a synchro-
nous one, on these kind of electronics?  How sensitive are computers etc to
pulse input rather than sine wave?  Would power line conditioners be required?

Thanks,
