Air conditioning on solar
So today I put together the three solar systems on the 8-D, hooked up the PowerJack inverter and then the 5000 BTU air conditioner. The Air conditioner is a Frigidaire unit that uses 446w/ 3.9a @120v....

"It seems to me anything under 29v or so and the controller nods off."
Hmmmm ... regardless of whether we're talking mono or poly panels ... who makes a solar panel controller that allows the panel(s) to still be connected to, and feeding, batteries all the way down to - and including - float voltages (i.e. 13.2 volts for wet batteries and 13.5 volts for AGM batteries)?
It seems to me that one (myself, for instance) would want every milliampere that their solar panel(s) could put out to be available for battery charging or maintenance ... depending upon what the batteries would accept at any particular voltage that was lower than their panel's intrinsic output voltage?
In other words, why don't I want a controller that acts just like a multi-stage charger to the batteries so long as the solar panel(s) feeding the controller can output slightly more voltage than what the batteries require at that point?
