![]() I haven't done this, but read up a bit, a while back.Ī 24v alternator or a heavy duty 12v with 24v regulator should both work alright, the trick is not burning them up with excessive speed. Could it be as simple as swapping the alternators out or am I missing something?Īny thoughts? Pro's/con's of 24v generator build? Anyone tried this? I can't find any info on doing this but I can't see where it'd be an issue? I'd only need half the amperage rating as compared to a 12v alternator, so I wouldn't need a heavy-duty one, if I'm not mistaken. That's twice the alternator expense though, and complicates the generator build.ģ. Wire x2 12v alternators in series to produce 24v power. Use a 12v alternator, run the power through a regulator that bumps it up t o 24v, which the alternator should be able to supply- BUT this will likely burn up the alternator / shorted its lifeĢ. My options, so far, appear to be the following:ġ. I haven't been able to find much literature on 24v generators. We are actually about to build 2 generators (using 200cc motors) ourselves, and I thought, well, why not make one a 24v generator? I found some info on building a large transformer yourself but I don't want to do that. I can't find any sources for high amperage (over 10amps, at least) step-up transformers, so I tossed out that idea. The major kink with going to a 24v system seems to be charging the batteries with a generator when the sun's been gone too long. Our panel setup is 810watts / 24v (really 45v of course). We have multiple MPPT charge controllers that are variable 12/24v and have 6v and 12v accessory ports. So I figure we can meet that need by either using a low-amperage step-down transformer to supply 12v power from the 24v bank, or run a line from the charge controller's accessory port to a switch or series of switches that will supply 12v power to these light strips. We have only 1 need for direct 12v power a few 12v lighting strips. So we're thinking of upping the 12v system to a 24v system. ![]() DO NOT hork this thing together like you have been aiming to do so far.Okay. Call an electrician, or learn proper wiring methods and fit your own box. I would say that is also true of the wall-wart transformer you really want.īut you don't really want a wall-wart transformer, you want this thing, hardwired in and installed to code. The key to this type is you let the thermostat wire do the traveling, you fit the transformer in a less finished utility space, crawlspace or basement where that makes sense. (or the electrician also could, obviously, and they're experienced at fishing wires through finished walls without wrecking drywall). You use thermostat cable to take the 24V wherever you need to go. Alternately, she can fit one of these boxes at an appropriate location, and then use listed wiring methods compliant with the Electrical Code to bring 120V mains power to the box.Īt that point, the electrician splices the transformer's 2 wires to mains power hardwired, fits the transformer as the box lid, tightens it down, and leaves. Now, if your basement is unfinished, there's likely to be one of these junction boxes somewhere, with handy circuits behind it your electrician can tap. The non-hazardous low voltage terminals are to be on the outside of the box. Code requires it be mounted with the AC power (black and white) wires on the inside, where they will splice to AC power wires also inside. As you can see, your transformer is made to be the lid of this. ![]() They're so common Amazon doesn't practically sell them, since every hardware store and electrical supply stocks them for about a dollar. Enter products like yours, which are designed to mount on standard 120/240V steel junction boxes, common as dirt in 120V wiring methods: ![]() However for thermostat wiring, the above is a silly product, because generally speaking thermostat wiring is a permanent part of the building, and there'd be no reason to make it pluggable, and a lot of reason not to. You're running smack into that right now. In mains electrical, wiring methods are everything.
