Hello,
Can anyone help?? I have a Honda 20EU generator and was considering putting in a split system air cond in my van, mainly used as permanant site. Would this
generator power this air cond? Here are the stats on it.... I know about the warranty issues.....Its an old van and just looking for a cheap option.
3.2kW cooling capacity
3.3kW heating capacity
Heats or cools an area of
30m² to 40m² simultaneously
(about 3 to 4 squares)
Or I could get a smaller one..
2.50kW cooling capacity
2.75kW heating capacity
Heats or cools an area of
20m² to 30m² simultaneously
(2 to 3 squares – about the size of a bedroom)
any opinions are appreciated. Many thanks

If you could give the full load amperage and whether it is an inverter model or a conventional compressor type air conditioner, then it will be easier to evaluate whether or not your genset will handle it. Be aware that your 2 kva Honda won’t produce 2kva continuously as this is its peak rating.

I think they are 1600w continuous.

Are you saying you have or will have an onsite van and want to power the AC with the generator?
For me, the first thing that comes to mind is....are you allowed to? That is, use the generator within the caravan park? During the hours you will need to run it?
Secondly, it's a rather inefficient method of producing power, particularly long term, so would therefore be expensive.
I assume there is no option for onsite power?

Thanks for your replys.
I believe the air cond is the inverter type. No intention to use generator in caravan park as I will would have mains power there. Just when I am away from mains power i would want to use it. If anyone could confirm if the generator will power it would appreciate it.
Cheers

I have a Honda20eu and we run a 9,000btu panasonic inverter type split system without any problems.
You do need the soft start or inverter type.
We start it on dark and it runs all night on one tank of petrol

The use of Btu’s or kW to quote the cooling capacity can’t be used to accurately determine the amperage or the input kW needed to run an airconditioner because different makes have different efficiencies. You need to find out its input requirments or else buy the 9,000 Btu Panasonic quoted here because beaul has tested it on thier 2kva Honda

Hi Dennis
I assume you are referring to the power factor?
What about if he runs it on 240 and uses a tong tester? Still might not help with start up current though?

Hi Lyndon
The difference is not in the power factor of the motor.
A 1 kVA motor driving an inefficient air conditioner may have a 1 kVA cooling capacity.
A 1 kVA motor, with the same power factor, driving an efficient air conditioner may have a 1.5 kVA cooling capacity.
It’s not a simple E x I calculation and the subject is better followed up on those websites that specialize in air-conditioning calculations.
Yes if he measured the full load amperage with a tong tester that’s a big help.
Yes starting currents have to be considered – these can vary depending on the type of motor.

Somewhere on the air con there will be a figure stating the watts that the unit actually uses and this is what you need to know. If the starting wattage is below 2000 then your Honda can run it.
However you must turn off all other 240v appliances until after start up.
EG. battery charger, hot water service, radio or TV etc.

With a normal electric motor compressor you need nearly double the power to get it started.
With an inverter type compressor the motor starts slowly and gradually speeds up to meet the required load. As I said my Panasonic split air conditioner (reverse cycle as
well)was not cheap ($1,000) but it worked extremely
well with the Honda.
9,000 btu is not a lot and I think you could go to 12,000btu with the same Honda. We used it on a boat, originally we had a 2,000watt Kiporgenerator and after 2 months threw the Kipor overboard and bought a Honda. No more problems.

Hi - thanks again for the replies -below is a chart of what the air cond is. I am looking at it from a company called Ayre air cond. I dont believe it is the inverter type. The person that sells also states they come with a warrenty even if you plac it in a caravan. So with these specs is the Honda 20 going to power it?

Now don’t hold me to this.
If your air conditioner was an inverter type – your Honda will run it
If it’s a standard motor then it’s getting near the border line on starting current but my guess it will start it.
I would tell the supplier that I’d buy it if the genset will start it. Take it to his
shop and plug it in.

Rated cooling power input W 680 950
Rated heating power input W 680 940
Looking at those power numbers, it looks like the 2Kw Honda would do it easy to me.
I'm assuming the 950/940W are the peak or startup figures.

Thanks for that info that really helps me.
So my next question is if the air cond is not a inverter type which I dont think it is - is that a big deal?
