Community Reviews

This Firman dual fuel inverter generator is valued for backup power and travel trailer use, especially on propane, which avoids carb gumming and keeps fuel maintenance simpler. It has handled outages well, and the electric start plus dual fuel setup make it practical for emergency use. The main cautions are battery reliability and storage, since the battery may lose charge within weeks or months and can prevent starting on propane if it dies. The CO sensor can also fail or block operation, and refurbished units carry only a 90 day warranty. A solid option if you can keep the battery charged and plan around the sensor.

I've bought 2 of these and on neither would the battery hold a charge more than a month or so. I found a LiFePO4 motorcycle battery to replace them with and all has been peachy keen.

I have one of these from Costco, it's a great generator for my travel trailer. However I strictly use it on propane so I never have to worry about the carb gumming up.

I did also run into the problem where the battery died, and when the battery dies it can't start on propane. It's also extremely difficult to jump start it the way the battery is mounted inside the case.

My long term solution was to buy a ring terminal to EC8 pig tail that I let hang out the back of the generator. The EC8 plug goes directly into my lithium jumper pack and starts the generator better than the factory battery does.

Could you share the model number of the battery?

I don't think that version of the predator is an inverter generator though, right?
Nope, it's just a regular generator; which is what you want for a whole-house.

An inverter is good for Glamping or RV parks, but you need brute force too keep your entire house going (and to throw an extension cord over the fence for your neighbor's c-pap and fridge)

When you see those monster 22,000w Generacs (installed for $25k, plus $1k a year for maintenance contract) on the TV infomercials, those are not inverters either.

Salesmen will talk about 'clean power' and 'protect sensitive electronics' to sell you a complicated inverter, but if you look at all the review videos on the Predator 13000, they show 8% THD at full load. That's actually better than my power company, who brings 9% THD to the meter.

You want as simple as can be for a whole-house. Simple to maintain, simple to switch from Utility to Gen power. Because when you can't bring your generator online in an emergency, you are totally stuck; all of the generator techs are out servicing their clients who have maintenance contracts.

No I do not... I bought mine about 3 years ago refurbished for $340. At that time they were selling this generator at Costco. I never once saw it go below $599 new on a sale price. I maybe once heard of it going for $550 on Slickdeals but never witnessed it at my store. Please provide some sort of evidence it ever once went new for the price you are claiming..
