Default portable generator

Looking into a 2-3k camp series portable generator. Wanted a Honda EU3000is for a long time but Yamaha makes a good one too. Heard lots of people use dual Honda 2000's in series as well. Whats the best way to handle this? Looking for quiet (camping) to run the roof A/C & possibly another RV's roof air, if needed.

Two ac units will require at least a 40 amps.

Always buy more than you need...

Specs on the units should have current/power requirements. Look at those. 2kW = 16.6 amps. Two 2kW units in parallel gives you about 33 amps. You're always going to lose some of that in line losses, and you don't want to run the gens at full-power for extended periods of time.

Another specification to look at is surge/startup wattage. While an AC compressor may only need 10 amps to run, it might require significantly more to start up. My 2kW gen can pump 2.2kW for very short periods of time (surge watts), but I wouldn't depend on it. Get a bigger gen.

All I really need powered is "my" camper with A/C. The toyhaulers I was looking at had 4000 & 5500 Onans on them, more than enough. I just need a quiet reliable portable unit to run my stuff only. Anybody else can get their own.

If you're running an A/C, I wouldn't go less than a 3kW unit.

Two 2kW's in parallel give you a little more power with the option to take just one when you don't need the power of both.

Thats why Im looking at Yamaha & Honda 2000 series right now, to run in parallel.

I have the Yami 2400 and it will run the AC when the batteries are full but if the bat charger is on boost mod (most do for the first hour) and then step down I will not carry them together.

one thing i was looking at is weight the 2400 is 70 lbs and 3000 is 130. at the time i bought it i was in a camper so weight was an issue. ALSO yammi and i think honda have some with batteries on board for surge starts (yammi is 3000isb). the I S stand for inverter series the B is for battery these can surge start more more than just the I S.

If you plan to run the AC a long time Get the 3000 or 2x2000. now and then the 2400 will work if needed.

We have used the Yamaha 2400 for the last five years to run the AC on our camper. No issues and I would buy the same one today if I had to do it again.
