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....

The spec says maximum charging current.
What in the spec implies that this means only a 10 amp charge controller is used?
Bear in mind that only a very slight improvement in the efficiency of any given solar charging system can give a dramatic improvement in performance (amperage output) - since most run of the mill solar systems are so inefficient as delivered. Not counting the variations in solar panel controllers, the solar panels themselves range in efficiencies from the low 20% range to the high 40% range.
What I assume is that maybe paying high bucks for a solar system will occasionally get one a higher efficiency system - which will translate into higher charging currents and hence a higher wattage rating for their system as a whole. Roc-Solid may be doing this for their "120 watt" portable system.
