How to choose

Inverter or open frame

In this class you can choose a dual fuel inverter (quiet, clean power) or an open frame (more watts per dollar, often 240 V).

Mistakes to avoid

  • Overlooking the weight: many 4,500 W inverters top 90 lb.

Frequently asked questions

What will a 4500 watt generator run?
