251 RKS and Portable Generator

Hi all, I just a bought a portable generator, a 1200 W Pulsair. The gen works great and it had a really good price. ($140) My question is this? When I plugged the TT into the gen it immediately started to work hard. I double checked everything and nothing was on or working other than the microwave. Then I turned on my TV, some lights, and the refrig, and the Microwave was also on. There wasn't any change in the working of the gen, they all worked good. So I'm wondering what is causing the electrical pull on the gen? It's no big deal just has me wondering.

The gen is just what I was looking for, it is light weight, (2 cycle) (35lbs) can run all the electrics I want run and is not that noisy.

Check your water heater if it is on electric. Also the converter would be charging the battery.

Most generators quote their surge load capability as the capability.The specs on the Pulsair are 1,200 Peak Watts/ 900 Running Watts of power . Your microwave draws a considerable amount of power. Without knowing the size of the microwave, it is probably between 700 and 1000W which is probably the normal load capacity of the generator. Also remember you most likely had the converter on which can draw another 100-200W.

The big electrial load was probably your converter recharging your 12V battery. And maybe your waterheater element if you have an electric capable water heater.

Is your generator perhaps a PULSAR brand 1200W generator? I could not locate any generators with the Pulsair brand name



Not familiar with your specific generator, but I have one that looks identical except it is painted blue with different stickers (probably is identical!!) Those little 2 stroke gennys are usually only good for about 600, maybe 700 watts continuous, with a really, really, really, really optimistic surge rating of something like 1200 watts. I think they probably "can" make that surge rating, but only for a few thousandths of a second until the momentum and rpm of the rotating parts slows to the point where it is no longer possible to maintain that current flow and voltage, much less frequency.



With your converter charging, and your refrigerator running on electric, you're very likely going to be maxxed out on that little generator. I'd be interested to see what your voltage and frequency is!!


Good luck with it, but I'm almost positive you'll be wanting more generator in short order

With my Generac 2000watt Inverter Generator if I turn on the microwave it will work harder. Yours will work even harder.
I wouldn't use yours for more than charging your batteries. I feel it will take a long time to charge your batteries. I am assuming you have more than 1 battery.
I have 2 24 series on my 251rks. I just upgraded my converter to get better charging of my batteries.
Good luck!!

You should have bought a minimum of a 2000w inverter generator.

A 1200 watt generator will only produce a max of 1000w of continuous power.
1200 is surge for start up. You maxed it out with the micro. Probably 900 watts. Other things my have run but not for long.

Not sure, but I think he meant that the clock was on on the microwave... not that it was actually nuking something.

Good be. When I think of a micro being on I'm thinking in use not just the clock.

Bingo!!!

The OP saw his micro "ON" with the clock working.

The gen purchased was likely THIS ONE and will provide enough power to run the converter and small AC plugged items.

No way in Hell will it run the microwave, AC or water heater on that little gen. The converter alone is likely rated to pull up to or more than the gen can provide for that gen.

That gen isn't bad but the expectations should be to run nothing more than charging batteries are power lights, TV, and DVD player.
