Off the Grid Listening-HELP!

jbs, thanks for the link and the formulas. I think I will need 400Ah worth of battery in a 24 volt system to start. Charging may be rough. I will need to see what solar can accomplish with the light I have, but it may be that I need to use solar and a generator. Much appreciate your input. I feel like I have some direction. Now, after buying a new Lyra phono cartridge, new phono pre (PS Audio), Audioquest Niagra and a few other items in the last year I need to save up some pennies for this!

jbs, wouild you please clarify what you meant by, "I'd opt for the low power route and make that tradeoff but that's just me. Big loads are expensive and get complicated to build in that capacity unless money and space don't matter."

Thanks in advance. Also, any reason not to go with lead acid batteries here since weight and space aren't issues?

You have a great idea going. You have isolated the listening room entirely, and have been very good at planning this whole idea. Having had some experience with batteries and converters, I would say that as long as you have what you need in battery power to begin with, the only other concern would be a decent sine wave converter. Most of what I have heard is that these devices usually provide an inferior (spikey) sine wave compared to commercial power. It might be a thought (and yes, more power needed) to run a PS Audio regenerator to make right that which will be imperfect from your AC power source. 

4krowme, I have read that most don't provide as pure a sine wave as commercial power does. I wish there were more data on the distortion of the sine waves! 

As I mentioned in my original post and you said a PS audio Power Plant may be needed. Not cheap though!

sorry for not explaining. I was just noting my personal preference to utilize low power gear as the system design is simpler. Fewer batteries, smaller inverters, less wiring, much easier to power and charge batteries. But that is me. 
 

lead acid are what I have but they are specialized for off grid (ie. not the regular RV or deep cycle auto batteries which are the most cost effective) use. AGM Matt so they do not require water and have minimal gassing off. If you get old school lead acid batteries be sure you are good with adding water and inquire about gassing off. You don’t want the batteries in same airspace you would stay in for long periods of time. Ventilation can address this. 
 

I have never measured the cleanliness of what my inverter puts out. Audio System is dead quiet so that works for me and no fired electronics to date. Brand is Schneider but many good brands depending on exact sizing and needs. I can run a 220v generator into the system to charge the batteries if needed. If you want that type of flexibility gotta inquire on the exact gear early. Solar can run everything for me but have an easy line of sight to the sun and do not need tons of power either. 3000w or 9 panels runs a small house including well water. 
 

if you do get power working there LED lighting is super easy and very low power to add.
