honda 2 kva not running van

[glyn hughes]

hey guys I have a 17.56.1 2012 with a herron 2.2 aircon
I tried to run the van with a Honda 2kva but no luck it just trips out the genny
dose anyone know if the yammah 2.4 will run this aircon thanks

My 1kv Honda runs the air con on low cool.

we have a heron 2.2 and our 2kva honda runs it no problem hi / lo

 

[glyn hughes]

I had the guy from the shop out and he put his gauge on and said it was drawing 18 amps on start up and the Honda 2 kva could not Handel that but I read the specs on the Heron 2.2 and it's locked rotor draw was 18 amps it's quite weird because a lot of ppl with the same air con can run there's fine with the honda 2 kva if anyone has any ideas plz let me know

 

[crackacoldie]

Are you running anything else at the same time, like the hot water service?

 

[Coastrunner]

Yeh, I'm thinking something else may be drawing power at the same time.

I was surprised what my little 1kv generator could do. It came with the van.

It can run the air con on cool with the fan at low speed.

It can run my wires hair dryer on medium warm.

It can't run the microwave.

Nice to know I can run air con out in the sticks if I have to.

my yamaha 2.4 runs our 2.2 ac no problems .
the honda should run it ok.
we went the 2.4 over the 2 honda if i remember right the honda peaked @2000 but the normal max was 1600 and that was running close the the max where the yamaha peaked @ 2.4 but the normal running max was 2000

The honda 2kv should run it. But it would be running flat out. Smaller Generators might run your air con on a cool day but if the outside temp gets to hot when you need it, the genny would over heat. Bigger the better but its the extra weight you have to deal with. I have the 2.4 which runs smooth/quite but slightly heavy. But when the genny is in position you dont have to move it till you leave. Better/longer time on fuel also.

amp = watts /volts

2200/240= 9.1666666

Had the same issue with my geny untill i turned off the electric hotwater unit

I just tried running my 2.2 Heron with my dad's Honda EU20i. Would not run at all, would only run the fan only function. Checked the hot water system, all good. Turned microwave off at GPO, still no good. Turned battery isolator off (so it is in trickle charge), still no good.

Interesting that some can run it and some can't!!!!

Jeez mate i bet you're glad you could try before you buy!

The problem is the inrush current on startup. If it is pulling 18A at start up of the compressor, your 2kVA generator would only be rated around 9A.

So whilst the capacity of generator might be OK to run it, it will have a lot of trouble when it starts.

I'm looking at the Air Command IBiS for my van which is 2.8kw cooling and 3kw cooling, but the startup current is 20A, as a result to run that aircon, I would be looking at 4800w, so I need a 5kVA generator to run it efficiently, and not overloading the generator.

Obviously this is a much larger and heavier unit, but that's the trade off if you want to run aircon.

We have the Yamaha 2.4 it runs the air con and heater no problems just if you want to use the micro as well we turn off the air con otherwise not powerful enough for both at same time . We stayed away from the Honda 2.0 as the salesman told us it would not run the air con

 

[gspy4u]

have a 17.56.2 and our Supercheap Blackridge 1700 runs our aircon fine. Will even do the hot water system by itself although it's getting close for that but the aircon runs fine. Actually the Heater part of the aircon draws more when it starts up than the aircon. Have not run it in 40 degree temps bit do not plan in being in the van in those temps anyway for now.

Did another check with a mates EU20i and it wouldn't run with that either. It did however run for a little longer before the generator gave up. I measure the voltage when running my dads and got 242Vac. It got down to 170Vac when trying to start the compressor in the A/C. At 2.2kW and 170Vac the current is 12.9A, obviously didn't like it!!!

Gonna try to find someone in town with a 2.4 Yamaha to try to see if it will beat the dreaded inrush current and get the A/C going!!!! Then I will buy one if it works!!!

The Honda EU20i is rated at 1.6kVA with a peak of 2.0kVA, whereas the Yamaha EF2400is is rated at 2.0kVA with a peak of 2.4kVA.

Whilst a few others have stated that their Yamaha 2.4's run it fine, even at its peak capacity, its only capable of 10A, with a locked rotor current of 18A, every time the compressor starts it putting significant stress on both the A/C and the generator.

If you are only looking at running the A/C from the generator every now and then, it might be worth the risk, but if you are looking at significant lenghts of time running from the gene, then you run the risk of damage to either or both units.

Sorry if somebody has covered this but if you run your geny to the van on a long 240v lead just maybe the voltage drop over the lead on maximum start up current may be excessive & drop out the geny. Try a short H/D lead
Just a thought.

Locked rotor current is only drawn when the rotor of the compressor motor is at a standstill, which is only for a split second then drops as speed increases. The EU20i which I tried today only ran at full noise for about 5 secs before stopping on overload. With an extra 400kva on offer I think the Yammie will have the capacity to start it, but I want to know for sure before handing over my money or else it will just sit in the shed!!!

 

[Hubble80]

I borrowed a mates 2.4kva Yammie the other day and got to try it out yesterday. Wouldn't start the A/C. Just for kicks I swapped leads as the one I was using was an extra heavy duty 10A builders lead. I tried the crappy 15A lead that came with the van and it worked!!!!

Gonna get my dads Honda eu20i again and try it with this lead and see if it will run!
