Any idea on "cleaning" dirty electricity from dual fuel generator?

How about telling the lv2424 mppsolar inverter it is "just too sensitive"?

Ought to have a wider voltage/frequency range it accepts in the case of a generator.
My Sunny Island has grid frequency range 59.3 to 60.5, but generator 54 to 66 Hz.

I just told it to lower its standards, it refused and still wants 57.5 to 61.5. Hz. There are days when I think it just does whatever the heck it wants.

In the event I have grid and generator on a transfer switch, there is a digital input to Sunny Island to indicate which.
That supports different current draw, backfeed grid but not generator, etc.

System could also be configured as stand-alone, no grid.

You may have similar settings or signaling inputs so it knows that is seeing generator vs. grid.

Do you have a frequency meter? My DMM has that.
As somebody said, a load might help. Could be with no load it runs a bit faster.
 
Stability of frequency is more critical then absolute frequency range. If generator engine speed control is slightly unstable and thrashes back and forth the inverter cannot lock on phase. The inverter phase tracking rate is very slow and it cannot hit a moving target. Because inverter may be supporting output loads it cannot change its running phase too fast.

been using my kill a watt for measurement at the generator and the lv2424 has one as well. I think I may have figured it out. I moved from 500 ft elevation to 5500 so I ordered the correct jet for my altitude. I’ll check back in after I get that part in.
 
That could be it.
You could try putting a space heater or other load on the generator, see if a different operating point makes it run better.

Funny, I've never had to pull over to the side of the road and change jets driving up to Donner Pass. Nor flying a light plane over a mountain range.
Oh, right. The plane had mixture control knobs. The older carbureted cars just ran rich. Your generator is probably some CARB approved or other clean/lean burning model. Close the choke part way?

You know what’s odd is that last night I plugged it in and it charged. It’s so random that maybe I’m barking up the wrong tree. I guess time and effort will tell. We’re off grid so there is always some load on the generator and I have tried with various amounts of load. It is a CARB model that I moved with so I can’t mess with much. I’ll keep on it and I’ll post the final solution ( which I really think is more batteries)
Thank you all for your help!!!

Hi, did you ever get this figured out? I’m having the same issue with dirty electricity and Hz variation. It charged fine on my expensive Honda generator but not so much on my cheaper WEN generator. My Honda is down for now.

I change it from UPS to Appliance, also helps to change the RPM of the generator, it was on 63 hz max, i took it to 60-61hz and works fine, also, newer models are less annoying, it might be something about the software, you could try updating the software too, i didn't update my, but I bough 2 lv2424 later and they both accepted the power from this generador without changing anything
 
I know this is an old thread, but I was just fighting this same thing on an lv5048, and came up with a unique solution. Thought i would share. I tried adding a resistive load to stabilize the output, but it didn't work, then I was thinking of how an inductive motor load backfeeds power while it runs and thought "i wonder" hooked up my hf belt sander to one leg, inverter immediately qualified the gen and started charging. After messing with a few settings to figure out where the sweet spot between charging and powering loads w/o tripping was, I could use the sander to get the power qualified and then shut it off once the inverter started loading down the genny.
