5 amps at that voltage is 2000Watts of energy, available for 5 hours at maximum draw, longer for lesser draws, of course.

If you are running a DC house (using appliances from Recreational Vehicle designs), you'll need to step it down. Less voltage, more amperage. P=VI

If you are running AC (typical consumer products) you have to step it down AND invert it. Very lossy.

Thanks for posting this. I want to look into it further...

Yeah, Volts is analagous to Pressure as it is call electromotive FORCE, Current is the Volume bobalew May 2015 #7

That's not a "Limitation", but is the nominal continuous maximum output. bobalew May 2015 #5
