4500 Watt NPS RV Inverter Generator Technology

Inverter technology allows for a better, more efficient design. The engine turns an alternator that produces alternating current which the generator rectifies into DC. An inverter converts the current back to a cleaner, more stable alternating current. This design improvement allows an alternator to spin at a lower speed which reduces wear and lowers fuel consumption because the engine runs at a lower speed. When the load increases, the engine speed can increase to provide additional power.

Next-Gen NPS4500eco Hot Weather Generator

Generators that run in hot weather overheat and then shut down to prevent engine damage. It’s not easy to keep a generator cool, especially enclosed in its own shell which is then mounted inside a metal box on the RV. With a specially designed air intake that provided improved air flow, the NPS4500 stays cool even in the hottest weather.

Next-Gen tested the NPS4500 for over 1500 hours in Death Valley during the summer where scorching temperatures reach up to 134° F. 

The 4500 Watt Next-Gen meets all CARB and EPA requirements for sale and use in all 50 states.

Meets National Park Service rules for noise and is equipped with a USDA Forest Service approved spark arresting muffler.
