looking at this generator for my uncle (old) and i think it's a good deal what do you guys think... Thanks.

BeGreen said:I've checked at least 5 sites and can not find true specs or a manual for this DuroMax unit. As I can tell it is not an inverter generator and does not provide true sine wave power. But I could be incorrect. If someone has the manual and can check that would be great. My suspicion is that is produces a modified square wave, otherwise they would be marketing this feature heavily. What I did find when checking on the BlueMax 4400 was that although the motor appears to be strong, the generator side has had some issues with bad regulators and expensive stator failures. What is the warranty period on this unit?
Competing with the DuroMax is the Generac 5724 which appears to be the favorite 3.2kw unit out there. It has a 2 yr warranty. Also in this group, the ETQ TG32P is a top reviewer for this category and it does advertise true sine wave output. If you can work with 3.2KW (4kw surge) it's $100 less.

Yur hard on puters!BrotherBart said:I have one of those Honda knock-off engines on my splitter for the last three years and that sucker is super. As to sine waves this place has run for seven days one time and four days the next time with a bottom of the barrel genset and nothing has fried yet.
In fact one Dell desktop died the day before the last power failure and one that never got turned on during the power failure smoked up the whole house six days after the last one.

I always thought that the only way to create that choppy modified sine wave waveform was to create it with a cheap inverter. Spinning a magnet around a pole to create AC should by default make a nice curvy sine wave.
The market for 3000-4000 watt gensets is dominated by those gensets designed and marketed to the RV crowd since that is the wattage required to run an RV's air conditioning unit. The RV crowd loves the Honda inverter gensets (usually two 2000s paired) and the Champion/onan/oriental chinese generators and odds are very slim that any significant market share is owned by generac except for the likely instance where generac has bought and rebadged one of the chinese gensets with their own label as onan did.
BeGreen said:None of our UPSs would accept power from the contractor generator we had (Coleman) which was a drag because I needed to recharge them. We ended up going for a modified gas/propane generator. Propane will keep for a very long time, gas won't. Last power outage, the gas stations were out for several days. When they got power, they were out again in 24 hrs. only this time they were out of gas. We need to think earthquake here. If a serious one hits, we might be on our own for several weeks. So a very efficient, quiet generator that works week after week and runs everything is a priority.
Highbeam said:You can buy relatively cheap kits to convert any of these gensets into propane or dual fuel propane and gasoline. Even the inverter hondas. If I had a large LPG tank onsite or NG service then I would for sure modify my genset to use those fuels. Are the gas powered sets really quieter? I can't imagine why but that would be another benefit.
BeGreen said:My understanding is that it also burns cleaner which is noticeable in the oil staying cleaner, longer.
