Owner pros and cons
Champion 8500W Dual Fuel Inverter
- +61 dBA claim holds at light load — dramatically quieter than open frames
- +50-amp 14-50R outlet feeds larger transfer switches
- +Propane option avoids stale-fuel problems for storm storage
- +Clean inverter power safe for HVAC boards and electronics
- +Massive value against the EU7000iS
- −214 lbs — moving it over any obstacle is a two-person job
- −Noise rises sharply under heavy load
- −Propane derates output roughly 10%
- −Warranty service on a unit this heavy is logistically painful
Predator 9500 Inverter
- +Honda-class inverter output at a fraction of the price
- +67 dBA is remarkably quiet for 7,600 running watts
- +Clean sine-wave power safe for electronics and HVAC boards
- +Electric start plus ESC mode stretches fuel to 18.5 hours
- +L14-30R 240V feeds a transfer switch or interlock
- −90-day factory warranty — extended plan is effectively required
- −Warranty service means hauling 257 lbs back to a store
- −Carbureted; storage with untreated fuel causes the usual gumming
- −Heaviest unit in its class by 30+ lbs
- −No propane/NG option
