MEP501 28v to 120v

[budthatsmyrealname]

I have the mep501a, has the yanmar l48a

i saw a couple old videos on the conversion from 28v to 120v. But those gen heads are nowhere to be found. Id rather direct drive and not belt drive, anyone know of any compatible gen heads? Thanks

Check with @CallMeColt here on the forum about the conversion and mechacical interface to the L48. He dud a YouTube video about one he converted.
I've converted 831s with the L70 to conventional gen heads. It uses the J609B configuration. The L48 may be the same.
I buy the gen heads direct from Mecc Alte.

Yes. That was one of the videos i watched. He posted a northern tool with model number but its discontinued. And when you click "search similar items" theyre all belt driven options.

Northern Tool stopped selling them a number of years ago.
Check out Mecc Alte for the gen head. They are a huge generator head manufacturer. I bought one from them about a year ago for a conversion.

What did you get? The closest i could find was Mec alte S15W-130 but this cant be found anywhere

This.... Info from invoice for the gen head I purchased.
It's a 4.2 KVA 3,600 RPM 120, 120/240 Gen Head with the adaptor plate for a J609B interface.
It's what I use to convert 831's.

I just saw this & the comment on you YouTube video. That was done quite a long time ago now, no surprise that parts are not longer available. I think the same interface from kloppk's generator head above will work. The J interface is the same if not mistaken across all models IF they have the J interface, and not the keyed shaft.

Thanks for the response. Anything in the 1800 rpm?

You won't find one of these small machines that generates power at 1800RPM. It's possible, but not practical.

Ok thanks. Great info. Ill go with the s16w 90/2. Is there anything else i need to get or know?

Be sure they send you the adapter plate. Sometime they forget to.
See my order confirmation for the details

In my opinion, I'd just leave the MEP 501A as it is & find a MEP 531A. In the end, it will be way cheaper. Unless you want the project of course. I wish I had just left it together, but at the time, had no need for the 28v. I'd love to have one again.

 

[budthatsmyrealname]

Yes i agree. Already set up is better. I do love projects, but this is what was available at the auction last week and it was my only choice and i need a small gen around 2kw

much appreciated on the responses. Maybe ill post a pic when im done if anyone is interested in seeing the end results

I didn't realize until just now your location... that makes things a bit more challenging. I have refurbished ones to sell but it would not be worth the shipping!

Depending on what you want the power for, you might look for a 24V inverter to get your 120VAC. Prices have come down a lot, though I give you that a bunch of power semiconductors might not have the reliability of a copper coil.

Good luck,

Yes i thought of just hooking up a pure sine inverter. I could not find one that had 28v input. Unless you know of one i could definitely use that info. I only seen regular inverters and modified sine wave at + or minus a few volts but nothing saying 28. I was gonna use it for electronics. So clean power is important

Most should accept 28V as it is in the range of charging voltages for a 24V battery bank, e.g. this pure sine 2kW inverter accepts 21-31V

I've never used this brand above personally, so I can't comment on it otherwise.

I have used other products from Renogy, and they were of reasonable quality. Here is a 2kw, surge to 4kW rated Renogy (23V-30.7V input);

If you think that you won't be using the full output from thenMEP-501, I might consider a battery bank of some sort between the MEP-501 and the inverter that might give you time to not run the generator. (At the cost of more $$$s and complexity.)

All the best,

Here is a really good discussion on charging batteries from many many years ago.

MEP-501a Question

So I recently acquired a Mechron version of the MEP-501a (ASB 2D/DND6) - I really didn't expect to get it for the price I was willing to pay, but hey - I'll take it! Now I have a few questions that I'm hoping someone here can help me with. I want to use the genset to recharge a 24v battery...

So i called mecc alte, he said there was a smaller version, the S16W-75. You think thatll do better than the s16w 90/20? Just wanted to run it by the guys who have done this

this is a learning experience for me. So i appreciate the feedback

Keep in mind if you use a direct inverter, you will not get the needed surge amperage so your output from the inverter will be reduced. Batteries will be needed.
