We bought this generator early last to top up our new batteries for our 'off the grid' power system. Shortly after we installed 8 large solar panels and this generator is now redundant for us. I reckon it will have been run for under 100 hours and has been serviced, oil changed etc. The motor is Briggs & Stratton (13HP) and the generator is LINZ. RPM 3000 and running at 50 HZ. We paid over $3K for the machine. It has always been kept inside. It seems pretty fuel efficient unlike an old Honda generator that we had.
