Outlet breaker trips.

I used the generator during a power outage. It ran fine on propane - the only problem I had was that refrigerator kept tripping the breaker on the outlet. Is there a solution for this?

Quality unit

I bought this unit around a month ago. I’m familiar with it as I work at a retail store and I’ve sold these to customers in the past. It’s a really nice unit. Dual fuel, wisper quiet, electric start and plenty of power for my needs. Very pleased.

CO sensor works great

Purchased the iQ5200 several months ago. Nice quiet generator, just remember to point the exhaust away from the walls or the CO sensor will shut it down I finally figured that out ever since it's running like a CHAMP.

Couple Issues

I bought it in May 2026, i have had a couple of issues. The electronic start button stopped working. When I use the propane system it shuts down are a while for no reason.

Disappointing purchase

Purchased a Generac inverter generator on 4/26/2026. Would not operate from the first try. The generator would not run for more then one minute at a time then stall. It has been at the repair shop since.

Although it was difficult ro get through to the correct people at Generac, we eventually did and after reviewing our case, they acted professionally and quickly. Thank you.

Parts diagram unavailable

I was disappointed that I cannot find a parts diagram available for download or purchase anywhere online. The product is good, but owner support seems lacking in this respect.

More power than Honda, half the price

I have been comparing portable generators for some time for our RV. We purchased this GP2200i, second owner, still strapped in unopened box for $300. Got home, unpacked, oiled and started after several pulls. Quiet as a mouse!! Started my 3/4 hp bench grinder no problem. I feel it will be less troublesome than models with all the electric lights (bells & whistles). It has more power than units costing 400 to 500 dollars more.

Honda vs. Generac

So I've had my Honda 2000 for 9 years, run it every weekend and change the oil every month usually and no issues until now, carb dirty needs a cleaning. Picked up this Generac 2200 and have been running it every weekend for a month. I feel like it's a tiny bit quieter than the Honda, and it starts on the first pull every time even when it's below 32 degrees. And it really purrs, no missing or fast revving except right after start. Called Genrac people re extended warrantee and after market pieces and the customer service seems really solid. So now it's just a waiting game to see if the Generac has the same legs as the Honda, but so far, pretty nice and 1/2 the price of the Honda. Jack
