Question: IS your start up sequence as follows:
ONE: Start generator
Two: Start A/C?
If so I have an answer for you... Here it is:
When you first start the generator in the morning the converter kicks in and starts sucking major power to re-charge the batteries.. Like 10 amps in my case (yours may be different) that's over 1,000 watts..
The A/C also draws like 13-15 amps running.. And the Yahama simply runs out of power.
The solution:
Wait at least 30 minutes to an hour between Varoom and Cool OR.
Turn off breaker for converter, THEN start A/C (This assumes it's hot in there) if the A/C has an "Emergency" mode, use it. .THEN turn on the converter.. This may work depending on just how close you are to overload on the genny.....
Option 2 would be a smaller converter.. I have two converters here. one is BIG (80 amp and as I said it draws 10 or more amps when batteries are low) the other is variable I can throttle it down to like 20 or 30 amps if I wish, or open it up to 99/100 (Which it hit the other night when.. well that's a long story)
Here is my story:
COnverter 1 (Factory installed) Is a Progressive Dynamics 9180 with wizard, it is a plug in model mounted as far from the batteries as possible.
Converter #2 is the charger module in a Xantrex Prosine 2.0 connected to the batteries with a short run of 0000 welding cable,, that's a whole lot of copper and a very short run, LESS THAN 3 FEET.
I prefer the 9200 for charging and maintaining the batteries for several reasons but that dang plug.. Well sometimes I snag it and pull it and so I did a few days ago.
In one bathroom (Bath and a half model) I have a battery monitor, on all the time, it was showing very low batteries.
Since it was like middle of the night (in fact I think it WAS midnight) I came out to the Xantrex Remote panel and CLICK, took a look and saw it hit 99 amps.
Divide DC amps by 10 and add 10-20% for AC amps.
(WE do not charge at 12 volt we charge at 13 or more 13.2 is 12 + 10%, and the converter is not 100% efficient so the 2nd 10%)
