I dunno rick hard to say. I just pulled this info for an 18,000 BTU inverter aircon unit:

Electrical Info:
Power Supply (VAC): 230 / 208 - 60Hz
Consupmt: (rated / max) - Cooling 1532 / 2390 Watts
Consupmt: (rated / max) - Heating 1342 / 2300 Watts
Current: (rated / max) - Cooling 6.7 / 10.5 Amps
Current: (rated / max) - Heating 5.9 / 10.1 Amps
MCA: 15 Amps
HVAC breaker size: 20 Amps

Energy Star 18,000 BTU Ductless Mini Split Air Conditioner

Is yours an Inverter unit?

Yes, it is an inverter unit with no heating component, only cooling.

These specs might be closer to what I have.

In my opinion its close. If the Aircon kicks on and the fridge motor is running and all... I dunno.

Your aircon likely has a 20a breaker all by itself. If that generator has only 1 circuit @ 20a I don't know. Just seems really close for all your stuff to try and run off of 1 20a circuit.

Mine is yellow.

As far as what I plan to run during an outage:

2 fridges
A few lights.
1 AC
I will probably not be watching TV
I won't be using the microwave.

I am trying to come up with any large electrical draws and I can't.

No well pumps. Wonder if my showers draw very much.

I think it would be close if I turned on either of the two other ACs, TVs or all my lights. Again it is a bit of a guessing game.

ALOT I think mine is like 4500 watt and thats not even a big one. Microwave is a biggie too. TV Not much.

Its mostly the AC and Fridges.

My generator, of course. Seems to be a happy color for generators.

As far as I can see, it does boil down to AC, 2 fridges and a few lights. I have pared things down because I don't want a bigger generator. I think a 6.5KW unit should be able to handle it. We shall soon see.

I believe the trick is to switch on the power to the air conditioning unit first so as to provide its required power to start up. Then, when it is running and drawing less current, it will be safe to switch on the other equipment individually.

Agree

The one you've been looking at is not a 6.5KW generator.
Specs says:
Maximum power 5500W (= 5.5KW)

5.5KW equals 6.5KVA at a power factor of 0.85 (which is reasonable for this genset)

What is most worrying is the rated current 20A which with a voltage of 220V is only 5.2KVA at the same power factor.

I think you'd better look at a 10KVA genset..

Yes, you are right. The decal on the side does say 6.5KVA.

They do have an 8.5KVA model and of, course it is quite a bit more money.

This is what they had at ToolPro.

We are getting away from diesel but Sakari Generator - Page 2 - Koh Samui, Koh Phangan, Koh Tao - Thailand Visa Forum by Thai Visa | The Nation

some quotes

Whatever you buy don't take it past about 70% of rated load and you'll be fine.

Your next door neighbor, who has been without power but has had to put up with the noise from your genny, comes around and says "the bluddy power is back on - please switch that noisy thing off."

I thought generators were to be run around 80% capacity and never 100%.

Im in the 6500kw camp

How much was this one in the shop?

from the specs I posted before is it 1200-1330 w

Wasn't this an average though?

I could always do what Davis did and go in and just buy a yellow no-name 9KW generator and hang all the research.

I am just curious to know what I can get away with without going too big. My understanding is that there is a downside to running far under capacity as well.

Seems to me it was around 52K with the ATS.
