If your house batteries are dropping to 11.5v, this is some 80% of the capacity ... with deep cycle you shouldn't go below 50% or 12.1v. Dropping to 11.5v on a regular basis will drastically shorten battery life and is likely why it couldn't start the generator! I also have solar and replaced my house batteries with Rolls AGM (x3) this year - I don't drop below 12.4v overnight (about 20% drop).
This is good info...for some reason I did not correlate the percentage discharge to the voltage. It is not close to being linear. Normally, I do not drop below 12.2 or so. The stereo kills the batteries. So it is not going to be used while on the hook. The JBL battery powered speakers got here today and they are pretty nice.
