Seems that lots of folk really endorse the Trace/Xantrex SW-4024 inverter/charger. All well and good, no argument at all regarding the endorsement. Does the model number translate to be SW = Sine Wave, 40 = 4000 watts, 24 = 24VDC? If this is a 24V DC unit, that's great for the 24V coach owners. But what about those of us who own 12V coaches? What should we use that's the equivalent, or will a 4024 work for us, too? What am I missing (besides those few bricks that make up a full load. . .  )???? TIA, RJ PD4106-2784 (12V) Fresno CA | ||

Hey RJ: It is indeed a 24v model. AFAIK, a 24v inverter will not work on a 12v system, nor a 12v inverter on a 24v one. Seems that the largest Trace 12v SW inverter is the 2512 and I believe it's discontinued... now gone to the PS series (sine wave). Xantrex also makes a 2000w ProSine Inv./Charger in 12v. There's more choices in the modified sine wave camp, with a few 3000w models, which is a boatload of amps @ 12v (BIG cables). It's those big cables and the amps they draw that are the downfall of high-watt 12v inverters. I suppose you could run a 24v house side it you want to run a separate alt. and use an equalizer to deal with 12v loads, but you'd have to really want that sweet SW inv. to go to that trouble, IMHO. I need to get a house-side inverter set up in my '06 conversion, also. I'll probably go with a cheapo Coleman for now to run the microwave and other intermittent AC uses when the genny isn’t fired up running the rooftop airs. Good luck!

Your chassis batteries and your house batteries don't have to have the same voltage; most folks choose to have a seperate set of batteries that serve as house power, reserving the chassis batteries for their traditional use in starting and powering the bus. | ||

Im not sure if the big virtue ," pass thru and augmentation," is done on the 12v series. The big Trace lets you park at a dump with only 120v,12A and start the air cond. It will also follow a small noisemaker getting the Second Air cond started from as little as 3000w. This allows the noisemaker to be far smaller and run at higher % of its rating for longer life and fewer mechanical hassles. FAST FRED | ||

The SWW2512 Is the nearest equivalent to the SW4024, it has the same software and features including 60 amp pass through and 7000 watt surge and battery augmentation of limited input source of 120 vac the only real difference is the continuous output rating is 2500 watts instead of 4000 and it requires heavier input wiring. There are several sub models of the Trace inverters, mine is an SW2512 MC which includes the remote panel. I sure like mine. Regards Jerry 4107 1120 | ||

The SW2512MC ia no longer being made, but there are still a few for sale on eBay, usually refurbished for around $1200. I bought one of these a couple of years ago and it has worked flawlessly. The new alternative is the PS2512, which is a stripped down SW2512, but it requires purchasing a remote control board while the SW has it built on to the unit. But if you are planning on installing the inverter in a bay you would need the remote anyway. --Geoff '82 RTS CA | ||

The lower power units are the PS series and the new MS series. They both lack grid capacity that the SW has. The PS is available in 12 or 24v (2512 and 2524 respectively) and DOES NOT need a remote but will work with the same remotes as the SW series. Without the digital remote the PS cannot be customized to particular end user setup but uses standard defaults. It will power share with the optional digital remote. Have not read a lot abt. the MS series. They are marketed under the Statpower brandname. Sinewave in 1500 and 2000 watt but I don't know if it comes in 24v or not. 5 min. surge is 3500 and 5000. respectively. But, hold off a while. I read somewhere that Trace is coming out with a 7.5kw model that surges for 10 minutes to 14kw. May want to consider an articulated to carry it and the battery bank to power it. | ||

RJ, I'll add my voice to the recommendations for the SW2512. Now discontinued, but there's plenty of new ones stocked all over the country -- just need to hunt them down. Try eBay or solar electric dealers. The nice thing about the 2512 is you can get two of them, and a special signal cable they sell to gang them together in a "stacked" configuration. You can stack them in parallel to get 240/120vac output, if you needed 240, but, more importantly, you can also stack them in series to get 5kw @ 120vac. That'll let you run air conditioners, etc. Also, while the MC model is nice to have, you may find the standard residential model more widely available. Read this to find out more about the issues: http://ourodyssey.us/bus-e-trace.html Everything I wrote there about the SW4024 is equally applicable to the SW2512. HTH, -Sean | ||

RJ, another option or suggestion might be to install just the 24v alt. (50dn) and battery bank just to run the 24v inverter. More amps smaller wire size on the 24v system. This is something I did as I removed the entire 24v system from the bus and went to 12v with the exception of the 24v alt for my 3624 DR inverter. | ||

Umm, Stan -- did you mean to post this in the other inverter thread? It seems out of context here... -Sean | ||

Yes: Sorry about that. |
