Solar/battery system

[jeffj]

This past weekend I was up i the mountains at a friends cabin that is off the grid.  He has a solar/battery electric system to power the joint.  After several hours of listening to the simple ipod/yamaha/polk system I was amazed how good it sounded. Could this be partly attributed to the clean noise free power that solar/battery system produces?  Or was it just the whiskey and altitude?

Doc how about a battery powered amp?

All thoughts on this subject appreciated.

How good was the whiskey?

I'd imagine the quality of the power is highly dependent on the inverter used.  There's bound to be less grunge on the line regardless!

Yes it is very effective system.. I have been using it for sometime and my power problem is nearly solved.

How about a battery powered amp based on the LM386 chip?  It can run on 9 volts, not sure how much wattage that would be able to give you, but I've seen a few headphone circuits lately based on that idea.

You get between 1/3 and 7/10 of a Watt, depending on battery voltage and load impedance.

I think Class D makes the best sense - very efficient, no crossover distortion.

Otherwise you're looking at big-ass batteries.
