Champion 2500 generators in parallel?

**Ziptrekker** · 03-27-2021, 04:51 AM

Has anyone used two Champion 2500 generators in parallel? If so, how did you do it?

Would that be sufficient power for my 50 amp rig? I have a 50 to 30amp adapter. We plan to use AC and microwave (highest power users) but not at the same time.

Should an EMS be used? If so, which one?

I answered one of my own questions. For parallel connection, use model 100319 kit. It has a 50 and 30 amp connection. Still not sure about if it's enough wattage for our needs.

Honestly, we bought a Champion 3400 Watt Dual Fuel Inverter/generator. It has a 30 amp RV receptacle built in, it provides 3250 watts on propane, and will run 8 hours on 1 20 pound propane tank at 25% load. It has a 1.5 gallon fuel tank, and will power 1 AC unit and charge the batteries with either fuel delivery system. It weighs just a hair under 100 lbs. If absolutely necessary, we could buy a second one and the parallel kit to run everything in the coach at the same time, but, I don't think we will ever get to that point.

The one 3400 watt costs less that 2 2400 watt generators and a parallel kit (when you can find it in sale). We bought our 3400 on sale through Amazon for $300.00 off. It has a lower fuel consumption rate that two 2400s, and lighter than the combined weight (I think). No need for a propane Y connector... Just simpler, overall, for my simple brain to use. Just my 2 cents, adjusted for inflation.

I am also looking at this exact configuration. At 39# it is something DW can handle if the need arises. I like the larger unit (3400) but at 95# it a killer.

My research so far indicates that this pair will support one A/C without any difficulty, possibly both if I add the soft start modules on the A/C's. I'm looking at starting with one unit and seeing how it goes.
It would seem that the startup draw on the A/C units varies quite a bit from unit to unit. A single 2500W generator might run one A/C (and nothing else) depending on your exact unit. I am confident (not positive) that one of these generators would handle a single 15oooBTU A/C with a soft start installed. The Microwave won't be a problem on one gen unit, its only about 1000 to 1200 watts.

Two units, linked with the parallel kit, would handle a decent load (about 3300W continuous on propane). As with any generator set-up, you'll need to be conscious of the loads and your power consumption.

Keep in mind that my crudimentary thinking is based on propane, not gasoline. If you are going to be using gasoline, then the generators will produce a little more power than propane, so my confidence level goes up a bit more.

Anyone else currently using the Campion 2500? How does it perform?

Your question here is a little different than on your other thread about propane. Yes, you could use two of the smaller in parallel, but you're not going to be able to run everything simultaneously. You will need to be conscious of your power usage is all. One of the 3400 units might be a better choice as mentioned and you can work with a 50 to 30 amp dogbone adapter. Personally, we have two 3400s and a parallel kit. If needed, like height of summer, we can run both and have no concern for the power demands in our camper. However, we generally just use one unit. Our Champions are also backup power for our home so the cost was easily justified and payed for itself when the hard winter here this year had power lines down for days.

I always seem like I am defending the use of 2 small generators over one large one..... anyway......

I just posted on another thread that I have been using 2 Honda 2000i"s for over 12 years. I can run one AC constantly and use other appliances. We keep the water heater on gas when on generator. And we just make not sure to run the AC, microwave, and DP's hair drying all at the same time.

P.S. I only run one AC at a time (or at all).

The advantages for me are: lightweight so easily portable; can use just one when heavy amperage not necessary; can store in front bay.

Lol! I don't think it's a matter of defending. Either approach works. Fantastic argument is about handling with the tiny portables since they're so easy to carry! I consider ours mid-size in the portable world and because of my back just built a flip-fold ramp and platform to park them in the front storage.

As with engineering, every problem can be solved multiple ways and solutions are driven by the need-want. No one way is the "right" way. Same goes for selecting what portable generator to buy because ALL have shortcomings. Every single design and brand on the market, which are also far fewer than people believe because of the magnitude of private labeling in the market space.

Yeah, I know... I was just giving my 2 cents.

Bring an engineer, my way is ALWAYS the right way, unless the wife corrects me. All joking aside, yes there are many ways to skin a cat(fish). All have pros and cons. The biggest con to mine is the 100 lbs weight.

I'm liking the idea of a ramp to put it into the front compartment!
