PTO generator

Swblack1216 · Oct 12, 2023

I picked up a beast PTO generator bigger than I can run with my coyote CK 25, but I’ll get what I can out of it. My question is I need a new meter one I can see digital preferred voltage frequency and current draw. Any suggestions would be appreciated TIA.

That’s about what I ordered pretty reasonable prices. wish I had a higher horsepower PTO.

I have that thing. Works great.

What kW is your gen?

workinonit · Oct 13, 2023

I have a 25 kW almost identical to that. I made my trailer for mine so that I can get my welder on it.

Maple leaf, that's a nice unit, where did you find that meter, do you have a link?
Thanks

I see one meter on the generator, is that a hz meter?
Once you get her to spinning I find hz to be the more important measurement.
The voltage may have some adjustment but the hz are fixed to the rpm of your pto.
If the load is pulling your tractors engine down the automatic voltage regulation will try and keep the voltage up,
but you will see the hz slowing down.
I use the hz meter on the generator to set my tractor rpm when starting the generator up.

This.

Depending on what you're powering with the generator, some things do NOT tolerate the Hz being "off". If your tractor engine is getting lugged down, your frequency is being thrown off.

That meter is a volt meter. It's a fairly inaccurate, cheap meter. I verified mine with a DMM and do so everytime I use it. I need to mount one of those multifunction readouts on mine. As others said, frequency is key. It's one of the factors that have to be synchronized when tying a generator to the grid. The other is voltage. Since these gens don't tie to the grid those measurements can fluctuate quite a lot. I install and commission voltage regulators on large generators. This involves tuning the regulator to grid conditions. These PTO gens are like a black start in a power plant. They are their own little grid being controlled by that generator. Do that with caution. Most of all, make sure you are isolated from the grid at all times.
