Homemade PTO Generator
nice set up ,thinkin about doin same with a 2.3 kw genny but will probably put genny over the pto shaft and set it up on 3 pt linkage have 19 hp at the tractor shaft and 3 speed pto so trying to figuer out the different pto speeds as 2.3 kw will not require much power to run it , so low engine speed in the high pto gear and then adjust with the pullys to get correct genny speed ,made some enquiries and was told about 2 hp per kw for pto driven gennys so should have lots of power at pto .:)
better to operate the alternator at 3600rpm, stopped and nothing else. Saves having to replace voltage regulators with some excitation systems.
@ truck501- Thanks for the comment. May your 2011 be the best for you too.
WELL THIS IS ONE OF THE BEST HOME-MADE GENNYS THAT I HAVE SEEN TO DATE WELL DONE AND ALL THE BEST FOR 2011 … IAIN UK
@danielthechskid- Thanks and good observation, yes the genset needs to be installed on the correct side of trailer to keep from lifting during load. Good idea with the disk mower pto/pulley. Let me know how you make out.
Excellent job. I want to build a similar unit possibly using the pulley and PTO shaft from a disk mower.
You even mounted the head on the correct side. Since the PTO turns clockwise as viewed from behind the torque would have to lift the head up to try to flip the trailer. If the head were on the other side it could more easily flip over when a load is appllied.
@AlternativePowerMan- I ended up buying a digital hz/Volt meter and plugged it in to the genset. This helps me obtain correct V/hz. On this setup, I get 3600 required rpm at the generator shaft. At 3600, my tractor runs 2500 rpms. The governor on the tractor keeps me at 2500 rpm and generator speed needed to get 120/60hz. One thing I did not do and have since corrected, is that I bought a matched pair of V- belts. Unmatched belts cause belt slippage on double groove pulleys..
@Comfytees Hi, Charge controller is a CQ1210 mppt charge controller and can be found at Greenergy Star.
I have not tried it without a battery,but should work for small loads like led lights, hope this helps.
Hi, what brand mppt and any tests done to see if it really is an mppt? Also does the mppt allow power to the load without a battery using only panels?
Thanks for all the comments, this is a very easy and affordable project so don’t be afraid to try one yourself.
Looks beast man! Works great!
good job with the box. We’re making something similar for powering our RC adventures
VERY VERY organized sir! 5 Stars.
