Generators Harbor Freight Predator

https://www.harborfreight.com/genera...iii-63962.html


Anyone have one of these Harbor freight Generators for running your AC


My AC specs say minimum 3500 watt generator


Think this will be 4375 /3500 (100lbs) will work good ?


Or should I get the next size bigger 6500/5500 watt that weights more 180 lbs

An Inverter Predator 3500w will power your AC.

The two generator you've listed will be too loud to run while camping and not recommended.

I know they are more expensive, but you really need a generator that is designed for RV/quiet use unless you are never going to be in a campground with neighbors.

I agree with Seon, get the one in his link, it may cost a little more now, but better in the long run. ~CA

(also there are other very good similar units that are name brand like Honda, but the costs of them vs this one is a lot and not worth the extra costs imo).

The new Generac 3500 inverter genny is supposed to be quieter than Honda and have special surge circuit. a TT near me was using ones it's very quite less exhaust drone than Honda maybe a bit more fan sound.

Post #2 has the answer. You don't want an open frame generator because of the noise level. Also, you want an inverter generator in order to protect the electronics of your RV.
The Predator 3500 watt gen Seon noted will run your a/c with room to spare. It weighs about 100 lb.

Interesting. What sound level is too loud for camping? Who gets to decide?

The APU built into my truck is probably close to as loud as a contractor generator. I put over 100 hours on it the past 2 weeks of camping. I did not disturb a single person.

This one says its 3500 starting watts and is only 3000 running watts. My Duo Therm AC specs says minimum generator 3500 watts

I don't know what A/C you have, but for most the specs stating 3500watts are for starting the A/C. One the A/C starts it will only pull ~1500watts. You would have to check yours to get the specific wattage on your and should be listed in the specs. Point being if you have enough generators starting watts for the A/C, then you have plenty enough running watts as well. ~CA

Another thumbs up for the inverter generator Seon pointed to or one like it. Cost more, but "buy once, cry once".

If you search here, there are a lot of good reviews on the HF generators, but not those. They sell some that are as quiet as the Hondas, and I've seen posts on using them for several years without any issues.

Or they were polite and didnt want to start drama because they are trying to relax.
Or you ran it during the day limiting the noise pollution and again they dealt with it.
Long story short, just because no one said anything .

Some open frame generators are also inverters and run a few decibels louder than the enclosed ones. Champion for example only list 3db difference between open and close frame inverter gensets of similar rating.

" An increase of 3dB doubles the sound intensity but a 10dB increase is required before a sound is perceived to be twice as loud. ... The sound intensity multiplies by 10 with every 10dB increase."
