GENMAX Portable Inverter Generator, 5500W Ultra Quiet Gas Engine, EPA Compatible, Eco Mode Function, Ultra Light for Home and Camping Use (GM5500i)

Undersized and Weak Main Circuit Breaker has Reached the Point of Non-Usability after less than 150 hours of runtime! Originally when we first got this unit and put it into service we were quite pleased with its overall performance and very happy that we could power our custom cargo trailer conversion RV with it. Overall the generator has been a good product and it is very quiet, almost as quiet as the Honda. But I have a serious issue with how it is configured in regards to how the unit is advertised as a 30A unit. The company that makes these Genmax 5500W Generators only puts a 21A double throw circuit main breaker on a circuit that is supposed to be 30A. When I first used the generator to power my 30A RV the unit worked okay and was able to power my LED lights (almost zero draw), 2 small 8" circulation fans, the 10 CU FT refrigerator/freezer and the 15,000 BTU roof air unit. But if I ran the microwave or the 120V on demand water heater with any of the other stuff running it would trip the breaker but I was able to adjust what we used to ensure we stayed within the limitation put in place by the 21A main breaker. But now 2 and 1/2 years later that 21A main breaker trips with anything more than the lights and refrigerator running. This unit has like 4 different circuit breakers on it... 2 for the standard outlet blocks which according to the user manual are 20A. Then there is a push to reset button supposedly for when or if the generator is overloaded but no info on what amperage that is set for. Then there is the "21A Main Circuit Breaker" (If the unit is a 30A unit then the "MAIN CIRCUIT BREAKER" should be 30A or its not a 30A unit.) which but is the ONLY BREAKER I have EVER had trip on this unit. Now I have eliminated the possibility that anything in my RV is causing this issue because I have run my buddy's Harbor Freight Predator 3500 Watt generator and not had any issues with tripping the breaker on it at all. Like I said the fact that they used an undersized 21A main circuit breaker should preclude them from advertising it as a 30A unit... But that aside, I definitely am going to fix it and replace the weak junk circuit breaker and see if I can fix what is wrong with it.

We had some weather near zero degrees without electric power for four days in an all electric home. This unit will run what we need in an emergency. We had an electrician install a transfer panel next to our electric service panel and we can plug the generator into an outside receptacle for safe and easy use on a dozen circuits in the service panel during a power outage. We have not used this generator in an emergency yet, just enough to break it in and keep the seals lubricated. It runs surprisingly quiet for an engine this size. Servicing the oil is difficult because of congestion and the position of the oil drain hose, but it's doable. The battery compartment is cramped as well, but accessible because of the removable panels on all sides. It takes a little extra time, but is doable. I installed a jack to plug the battery tender in to keep it topped off for that day we hope will never come and we need backup power. The rope start works, just pull hard!

The title says it all. I had to install a soft start to be able to crank up my 2hp 220v pump motor. Shouldn't be a problem because the starting amps are below the max of the generator. Undersized breaker seems to be the problem. Anyway UPDATE saturday July 13th. Power went out Monday morning from Beryl and I've been running the house (except main a/c) with it ever since . Fridge, 2 small freezers, 2 window units and lights. No problem. Washer and gas dryer used this am. When I first got this thing I ran it for 2 hrs with 1500w load and changed the oil. Clean, no sparkles. Crank it once a month as part of my preps. Use Stabil blue. Always. Now it has 118 hrs, about 100 continuous and doing fine. I changed the oil again yesterday, normal looking. I did have to drain the carb bowl once because it started running really roughly. Must have been some contamination from me refueling during a rainstorm. I'm revising my rating to 4 stars. Only 4 because the oil access/drain area is hard to get my oversized paws into. That and an undersized breaker that limits starting power.

Here I am sitting on my back porch listening to the quiet running generator on a blue bird sky day when there should be no power outages. Turns out, someone clipped a power pole and now the power is off. I received the generator 8 days ago. The electric start feature is terrific and the unit started right up. It's powering all my electronic gizmos and my fridge, quietly. After the engine starts, back slowly off the operating dial from Start to Run. The dial seems to control the choke and the engine wants to die a bit if not warmed up for 30 seconds or so. It's a hefty unit and the extendable suitcase type handles and wheels make moving it a breeze for this senior. Glad I have it!

We had issues with our generator, so we contacted customer support. Generator just would not start one day. We used it fairly often and runs very quietly. They sent us a new starter for no charge. That didn't work, so I contacted them again. After explaining to them that my husband was a electrician and mechanic for over 30 years and could not figure out what was wrong with the unit, they indicated they would ship out a replacement. Was not the easiest to get in contact with them initially; however, after a few e-mails and about a month of going back and forth, they honored their warranty and sent us a BRAND NEW GENERATOR. They did not require us to ship back the original one. So, we will be keeping it for parts for this one if something goes wrong with the new one.
