Any experience with a Solar-Battery-Inverter System to power an Audio System?

I have a lot of problems with my home A/C system and have been searching for solutions. After reading another thread on power conditioners I was introduced to APC products.
After reading one review on them, the reviewer pulled the plug and was able to run his system on the battery back up for an hour.
This started me to thinking about using batteries with a solar panel and inverter. After all, that is what the APC is doing while in battery backup.
My 2 channel (300b) system is calculated to only draw approx 750 watts and therefore is not a heavy load.
The inverters that I have looked at have pure sine inversion along with voltage regulation.
Has anyone tried this or have any knowledge on doing this?
 
Years ago I looked at solar unless the cost has dropped a lot you will find this is very high cost. It could be done but I think you will find the cost is too high to do it right. Before you do any thing what will your insurance company say if you do this.
 
Have a gander at Tesla, they have a few ideas that may or may not help. A few years back I had a 5kw system that fed the grid & day or night my system sounded sublime, then again i did have a Silver Circle Audio[h=2]Pure Power One 5.0SE[/h]
 
After thinking more about this I don't necessarily need the solar panels. After all, my primary residence is in western Michigan and it is not known for its sunny side.
My thoughts were to get very clean AC power. The battery/inverter will do that side of it and the solar panels were to keep the batteries up. However I could use a battery or float charger to keep the batteries up.
I normally listen in the evening for 2-3 hours. I could charge the batteries during the day and take the charging side off line during the listening sessions.
It would be nice to have the free power from the solar panels. However the additional cost and circuitry could be bypassed with a battery charger.
I know a lot of homes it the U.S. are either all solar or have a solar back up. So it is clear that the technology is available. Insurance must not be a big issue seeing as there are so many homes using solar.
From what I can gather, several batteries, an inverter and a battery charger will come in far under what a great many of the current power conditioners are going for. And the power will be clean, regulated and off grid, therefore unaffected by the power company or any other appliances, dimmers, lights ETC from the home.
Is there a flaw in my thinking?
 
Limited impulse current can have a profound impact in transients. I am not sure exactly what this setup would do to instantaneous current delivery but you may want to understand this as I would guess it may not be a good thing. I fear the inverter/battery may be a restriction depending on how you engineer the specs.

In a similar way, I am not a fan of localized power conditioners that restrict instant current availability. I never cease to be amazed by people who will spend high 5 figures to get the last 1% of the speed of light in current transmission from their cables and then put a instantaneous current limiting power conditioner in front of the cables. It is NOT about sizing your rated power requirement to the device as instant current can be many multiples of rated current. Caelin Gabriel is really smart on this subject.
 
Yes Paul, you're absolutely right on the instantaneous draw that a system can demand.
Several things are in my favor in this application. They are the low power draw from my 8 watt amps and my 97 db speakers.
However it is something to consider when sizing the batteries and inverter.
I have been chasing a noise problem in my ac distribution system for quite a while. In desperation I have come up with this idea. Not sure if it will work or not, thus this thread.
