Sorry to bug you again...
But I am now looking at the Conext SW 4048 (not looking at the Radian because the price is a big high for me right now). But the Conext SW is rated for 4000watts and the by pass is only 30amps (grid transfer). I am worry that it's now enough to start my 3tons HVAC unit which pull about 13amps when running, but not sure how much is the surge.
But then I look at your set up, you said you ran water heater, dish washer, ect and a 2tons AC unit... But I look at the Radian 4048A specs and it said it only have a 15AMP AC Ultility Interact current? Is this the same as bypass AC? or something different?
Do you have any idea how much your 2tons draw on start up and running?
Tried Conext support, but they are somewhat rude and unhelpful.
