Question:

I am building an off Solar Panel Inverter wiring diagram-grid home in the Texas hill country.  I need a recommendation for a good propane generator.  It needs to be compatable with the Trace SW inverter.  The generator will be used to charge batteries when energy usage goes beyond what the solar panels can handle.  I want the generator to be quiet so it probably needs to be on the low RPM side.  Power generation should be from 5-12 KW.  Any advice would be welcome.

Response:

If you plan on this as a long term solution you may want to look at diesel generators, they are more expensive to purchase but less costly to operate and generally have a long life. You also want low speed (1800 RPM) for long life. As for quiet, locate it well away from your house and build a good sound reducing building, either lots of soft fluffy insulation or heavy solid wall such as concrete. You can make a great muffler from a 100 pound propane tank and then bury it a foot or so under the ground.Solar Panel Inverter wiring diagram

10-20KW GENERAC.  Look for a used one, Solar Panel Inverter wiring diagram I picked up two propane ones for the cost of the time to go get them before bulldozers plowed them under.  A new paint job, a $200 radiator and some transistors & diodes on the control boards and the one I got running works well with my SW5548’s.  Mid 70’s I figure, the 4 cylinder 2.5L engine matches up to a 1970 MONZA for parts. Check with your local cable company to see if they are upgrading any “head-ends” and have any old generators to sell off.

I recently purchased a Generac RV generator (6500 watt) that runs on propane. It was recommended to me by a fellow RVer as very quiet, extremely long lasting (motor runs 2700 RPM) and reasonable price. I called the seller in California and liked the vibes from him. He sells more than one make, therefore didn’t care which one I bought. he also said this was a 8000 to 10,000 hour generator if looked after well. Solar Panel Inverter wiring diagram I purchased it to provide back-up power for our small farm and for RV. It is 120 and 240 volt. I cannot recommend it yet, I haven’t even started it yet, busy installing. If you wish I would be happy to report in a few days when I try it out. The cost was $3100.00, but for your use some features could be possibly be remove i.e.: remote start, etc. Ed

Long term power production I would look into water cooled, and 1800 rpm. Fuel is your choice. There are pros and cons of any fuel.   Air cooled tends to be 3600 rpm.  Look for decent controls on the gen for voltage and hertz. Typically the 3600 rpm models are speed governed for voltage and hertz. You will need to check into a transfer switch as well.

I believe so,  You have a set of batteries and an inverter, Source 1.  You have a generator  Source 2 that feeds the same set of batteries.  The load is coming out of the inverter.   The generator is putting power into the battery bank and back into your panels unless you isolate them. Yes the panels have diodes to prevent back feeding. In my experience isolation with a switch, is best.  My intention is to get you thinking about the big and small picture and have everything designed and allowed for before the AHHH SHIT.   Been there done that and it was not much fun.

Response:

I think he meant that he would only need a transfer switch to switch the house mains between being sourced from his generator and being sourced from the utility grid. If you have no utility tie, then indeed you are not required to have a transfer switch for your generator. You can tie into the main service panel directly from the generator. You would obviously need utility permission to put power from an source ON their grid.

Hi Folks;   This thread started with someone asking about a generator “to charge batteries.”   I have only heard answers that refer to generators that put out 120VAC.   It takes a big charger to put more than a couple hundred watts into a battery bank. High quality, high output chargers also tend to cost lots of of dollars.  A typical 10Amp charger, like comes with many generators, or converters, would have to run 16 hours a day, to be able to put about 1.5KWH of recoverable energy into the battery bank.  What practical solutions are there for charging a battery bank quickly?   I have not seen any 12 VDC high amperage generator systems.  Are there no fuel systems designed to charge batteries?  I have seen auto- -motive type chargers in the 60 amp range for 6, 12 and 24V, with up to 250amp boost, in the few hundred dollar range, but question their regulation control (if any), and their longevity at boost power.  A 150 amp alternator could be hooked up to a 5hp engine, but that kind of generator does not seem to be a pro- -duction item, so will need to be built.  Got any recommendations for a system that can charge a 500amp hr or larger (12V) battery bank with 1500watt hrs (from a 50% to a 75% charge), in an hour, or less?

Odd how all the salesmen jumped onto this thread eh?  Been looking into ‘home power’ myself the past while.  Some generators have a 12V output  (not sure how ‘regulated’ they are) as well as the standard 120v. I’m leaning toward the little HondaYamaha  inverter series. The Honda says they have 12v outputs but only 8A (96W) to 12A(144W). Don’t have the Yamaha’s handy.  I’m on the edge of a power hurtin city, so as long as I keep enough fuel around (these little suckers sip fuel) I should be safe for a 2 or 3 day outage.                   Solar Panel Inverter wiring diagram   This thread started with someone asking about a generator “to charge batteries.”   I have only heard answers that refer to generators that put out 120VAC.   It takes a big charger to put more than a couple hundred watts into a battery bank.

Hi Wayne;   How often does yours get used?  What kind of alternator are you using?  I have a 5hp motor with electric start, that I bought for building a generator.  As I mentioned, I also have a 4000watt Honda RV generator.  I have not even investigated what would be involved in converting it to low voltage DC.  However, I like that it is very quite, and has a remote panel for monitoring, starting, etc.  It is also designed to safely be mounted semi-inside, in a vented box.

Ours (home made) puts out 70 A (24V system) Hi Wayne;  How often does yours get used?

Sometimes months between uses. Occasionally several days in a row. Not very many hours per year though. I used a single V belt, which I wouldn’t recommend for this load if it was going to be used a lot.  What kind of alternator are you using?

Just a regular old Delco, 100 A  IIRC. Paid $5 at the wreckers. Intended to overhaul, but it only needed cleaning. As used in older Caddies, heavy pickup trucks etc. Internal regulator disabled, a $5 rheostat used in its place. I have a 5hp motor with electric start, that I bought for building a generator.

Thanks for your response.   I am already familiar with marine alternators, and their multistage chargers, and agree with you whole heartedly on their efficiency and quality.  I’ll be installing that type of system in my campervan.  However, I already have the 4000watt Honda RV genset with many nice features. I would like to investigate my options for using it to charge my off-grid battery bank, instead of building a whole new systems, and letting that one set idle.  A big 120VAC/12VDC charger might do the job, but I am unfamiliar with what is available.  Perhaps a large wheeled, automotive type charger, run through a multistage charger, will do what I want.  Or perhaps for that charging range (from 50% to 75% charge) I will only need a timer. What is involved in changing the Honda RV generator from 120VAC, into a DC battery charger? As for the genset, diesel beats propane for running cost and lifetime.

The diesel I have is over size (2 liter), though I may set it up with a generator and power take off eventually.  Since I already own the Honda gas genset, as well as a couple of other gas engines, and live in the deep forest, I plan to eventually run my generator(s) on woodgas.

Laren,     Unfortunately, the only realistic way is to keep the generator unmodified, and feed the 120VAC to a battery charger. Keep in mind, the windings in the generator are rated for 33.3 amps – even if you could somehow change the voltage regulator to produce 12V instead of 120 without also completely redoing the control circuitry, you’d have 12V at 33.3 amps maximum. You would also have to run the output through diodes to rectify it to DC, since the genset is only going to (directly) produce AC.     Note – I’m not saying that it -can’t- be done – but even 12V/33.3A would be neither easy nor cheap, and anything more would require rewinding the genset.

Thanks  Alan;   That is what I thought.  I figure that it is a matter of hooking it to a different alternator (which might not be all that easy), or running its 120VAC into a big 12VDC battery charger (which won’t be very efficient).   Of course it is big enough to run power tools, while charging a battery bank.  It is a nice genset, but I need to charge batteries, and have no need of 4000watts AC, and I sure don’t want the noise for many hours a day.  I have a lot of options.  Maybe I will just use it for when I need a lot of AC at one time.  I might just sell it. ;O) Thanks again, Solar Panel Inverter wiring diagram

Yep, this unit is a “China Diesel” type engine, probubly air cooled. I have seen a bunch of them over the years.  They are fairly reliable, except the chinese bearings aren’t very good. (5000 hours or so) If you rebuild them with NSK Bearings, they are good for 15000 hours or so with good maintaince. (changing Oil every 75 hours)  A bit hard on the engine when they are loaded up to 3Kw, but will run for ever at 2Kw. Solar Panel Inverter wiring diagram

Onan has a good reputation for building reliable generators. They have ample service centers that stock parts for even older generators. They seem to hold their value well. Nobody publishes MTBF numbers for generators, but if you take good care of it I can’t see why you couldn’t get 10k+ hours out of it. A lot depends on how you take care of it. Regular oil and filter changes are a must. That model has some features that you do want to look for in a long lasting generator. Cast iron sleeves. Pressurized oil. Low oil shutdown. You will get longer life running propane or natural gas than gasoline. There is no washing of the cylinder walls past the rings like on a gas engine. Fuel does not spill down into the oil reservoir and dilute it. Oil stays cleaner longer than with gasoline. No problems with varnish build up in the carburetor, or fuel going bad. They are relatively clean burning, and you will not notice much odor. You can store large quantities of fuel safely. You do need to de-rate the power output for propane and more for natural gas. You are not paying road taxes on propane or natural gas. A 1800 rpm diesel will have longer life than even propane. They can be smelly unless you are burning vegetable oil in it. Diesel is a bit harder to store. You can use un-taxed diesel. Cold weather can be a problem (but probably not in Texas). That model is actually relatively quiet. It also has the advantage of coming in a weather-proof housing, something that you would normally would have to build yourself. It has remote control capability which is especially useful for home power setups. The Trace inverter can be used to control the Onan standard remote wiring setup. I have neighbors who have a similar RV type Onan, and they have had good luck with it for the past 6 or 7 years of almost constant (3 season) use at an off-grid camp with minimal PV solar. It has needed to be serviced a couple times for running rough, and at least twice because mice built a nest and fouled up the governor. They are not real fussy about oil changes and maintenance. The RV models are built with quietness compactness in mind. The compactness can make it a bit harder to work on. They also get a premium price for this type of RV model. But, if you can afford the price, I’d say that there are some advantages over many other types of generators, not the least is the quietness. I don’t think you could go wrong with it, but that’s just my guess. I have a propane generator that was re-badged by Northern Tool. It is a 9hp Briggs and Stratton Engine and a Gillette generator head. I have run it for 9 years, and only had to clean out the valves once. I probably put 10 hours a week on it for 5 months of the year. I expect to get at least another 9 years out of it. I change the oil once a year. It is very noisy, but has been very reliable. my $.02.
