We have the NextGen 5.5kw unit. It is smooth and works well. The generator head
they use is a bit light-duty and many fail after 5-7yrs. Good thing is that replacement heads only cost $700, which is still a lot of money
, but only a fraction of the cost of most.
Generators for 60Hz either run at 3600rpm or 1800rpm. The tradeoff is weight, with 1800rpm units being significantly heavier than 3600rpm. The Nextgen can run between that at 2850rpm because it uses a belt to drive the generator head
, so can use pulley ratios to run the head at 3600 while the engine is at 2850.
Like has already been mentioned, these are great light duty generators, but if you are looking for continuous operation of high loads, then a 1800rpm unit like Northern Lights
would be a better choice.
