Off the Grid Listening-HELP!

In the next year, I am going to have to move my dedicated listening room to being off-the-grid. I would love to hear from anybody with experience in this area.I am just in the beginnings of doing research, but if anyone can accelerate this process I would appreciate it. I would need to power my turntable, a phono pre, tube pre amp, tube mono blocks and a couple of class D sub amps. I know that I need a pure sine wave inverter (how big, what brand?) and a couple of deep cycle batteries. Is there any easy way to calculate the size of the inverter and batteries needed? 12 or 24 volt system? Would something like a PS Audio regenerator be helpful too? This would only best used about 8 hours per week in four hour sessions. Thank you!

jbs, I am with you on AGM batteries. I don't want to deal with adding water or the off-gassing with old-school lead acid batteries. This system isn't going to be tasked with running anything other than an audio system.

From ten years of running big AGM , diesel genset and inverter on a 47’ loa boat, i was profoundly disappointed with AGM performance and longevity Lifeline cost me a bunch of $$$$, Eventually i went back to lead acid low tech reliable with some noted constraints. absolutely nail down the system design and warranty. If it were me, i would put the genset in a hush house with auto start / off.

Best to you !

Jim,

Thanks for the tip on AGM. Come to think of it, I haven't had good luck with them either. I can deal with the maintenance of an old-school and have a place to put them so maybe I will go that route.
