I've run less-efficent A/Cs from a 15 amp outlet (many others have too) w/o a problem. The unit on the 'pod seems to be very efficient @ only 1000 watts while running, which is well below the rating for a 15 amp outlet (1800 watts). You could even turn on every light and run the pump. Just don't use the microwave or electric element on the water heater at the same time as the A/C.

I was told not to never try to start up the AC without at least 30 amp service so I have not but asking around I get various advice conflicts. What is the scoop on 20 amp service running the AC? It just seems strange to me that Forest River would put an AC in these units that you cannot use connected to typical home circuits.

My 6kw (12kw surge) inverter dropped out a few times when I plugged in the 'pod, so the converter has a big surge. It didn't always happen when I tried several times in a row so I'm guessing it has some big capacitors that get discharged fairly quickly but not immediately.
I did look for the surge on the A/C, I had my kid turn it on while I stared at the readout but it didn't respond quickly enough to give me a measurement. Typically you can expect 2 to 4 times the running wattage.

Anyone have any idea what the initial surge is when the Air Conditioning compressor kicks on?
My Yamaha EF2000iSHC generator drops off line when this happens.

I took wattage measurements of various appliances in the 'pod. What I was using to measure is only accurate to the nearest 100 watts (a heavy-duty inverter I have installed at home with a digital readout), but it can handle the startup surge of the A/C and converter which a Kill-A-Watt couldn't. I don't have a clamp-on ammeter or shunt which would be much more accurate, but this is "good enough". First number is Wh, the second is VA. Converter only, battery fully charged: no measurement (so something less than 100 watts) A/C, fan and compressor running: 1000/1100 Water heater, electric element: 1300/1300 Fridge, in AC mode: 200/200 Microwave: 1700/1800 Every light on: 200/400 Exhaust fan, low: no measurement Exhaust fan, medium: 100/100 Exhaust fan, high: 100/100 Water pump: 100/200 I forgot to measure the microwave's convection mode, and while I measured the A/C with the fan only I forgot to write it down. I didn't try to measure the television since it is probably less than 30 watts. Obviously the lack of accuracy prevented good numbers on the exhaust fan - someone found the factory-claimed amps for the 3 settings a while ago. Some things are running through the converter (lights, fan, pump) so there are conversion losses as part of the numbers. |
