Isn't a 50% discharge rate the standard? I thought that was as low as your were supposed to take them.
I don't know, I'm asking here, but I have seen the 50% battery level mentioned here often enough to wonder if it's really "silly".
My error, didn't explain enough. I added the following information to my original post:
The A/C would need to be set at a low setting to run 15 hours from a battery bank even with help from the solar panels.
It's a "silly test" because, during hot weather when an A/C is required for cooling, it's usually set at full power. At best the A/C could run for a few hours at full power from battery bank/solar panels.
We run a high tech split-unit semi-truck sleeper cab 13,000 BTU A/C in our rig, the manufacturer also makes fantastic claims about running it on batteries and solar.
Real world experience from myself and Truckers; can't carry enough batteries and solar panels to run it on high settings for very long in hot weather.
When the full spec's are listed for A/C btu, amps, battery bank size solar panels, I'll run the math to calculate hours A/C can run on high setting.
