Thanx For the info. and confidence Professor.
I have been looking at the IOTA 30amp automatic transfer switch and IF...if I see that by wiring a 3 way switch between the shore power cord and the generator...that I can indeed get the generator to carry the already running rooftop air conditioners load, than I think I'll break the bank and go for a pair of these transfer switches.
(wiring them in the order of priority I am desiring..shore power/inverter on one and on the second...the first units output/generator)
*I have also been staring down the AIMS 3 way automatic transfer switch...which to me is a bit nicer due to the specs they list and the verification lights for which source is being utilized.
-Its claims a switching time of 26ms. for seamless operations of items.
**I have to contact this company though, because I would want to wire my components in the order of 1.shore power 2.Inverter 3.Generator...and I have read that their units order of proirity cannot be changed..and that confuses me....(they claim the designed order of priority is 1.shore power 2. generator 3. inverter)
^^^Should my 3way switch test work properly...I am going to need to know a couple things to assist me with the next decisions I have to make:
-Will the use of a "Modified Sine Wave inverter" change the amount watts required to start the air conditioners compressor compared to shore power?(modified sine wave inverters are cheaper than pure sine wave)
-Based on the info. I provided..(air conditioner uses 1580 watts/13.20amps on high with compressor running, measured after unit was running on coldest setting for 1/2hr)...what size inverter should I purchase? (I am reading that the start up power may be 5x what its normal use is..thats 8000watts, does that sound right?...I mean, I have a 30amp service with a 30amp shore power cord running this now. That 30amp shore power cord is only rated for about 3500 watts, according to the math...please advise!! There is a signifigant price difference between a 3000 watt inverter and a 10000 watt unit.)
