For 2-3x the price they use top quality components through out. For
motors I hear they last longer but I really wonder, OHV engines do
last longer but no lawn maintenance people complain about their B&S or
use Honda. A motor thats runs at 3600 rpm has a life of about 2000
hours if not run full throttle, the inverter series of honda , Yamaha
etc can run as low as 900 rpm to generate a low amount of power. A 900
rpm engine can in theory last 100000++ hours. Honda inverters are
known to last 10000 hours when they are not being used to their
maximum output. Diesels last longer because of low rpm, If you want
long life cut the rpm in half and you in thoery increase life 4x.
There are 900 or 1100 rpm generators that do last 100000 hours, they
use a motor designed in england and now made in India. I forget their
name but a 5 hp unit might weigh over 100lb and has a 3ft flywheel.
For a 3600 rpm unit I dont know if they do last longer, maybe by the
design of using a larger motor so it isnt taxed as hard honda might
do. Maybe the unit is of a hevier duty design and out put is
conservative , that would make it last longer. One way to compare 3600
rpm units would be weight, a cheap 500$ gen I know weighs alot less
than a Honda, The extra metal is where its needed.
