Unexplained Voltage drop in my system under no load, need some advice.

Do not under any circumstances go below 12.3 volts or 50% DOD. With the stated load you mentioned of 60 watts x 8 hours = 480 Watt hours will require a 12 volt 200 AH battery.

You wouldn't have to worry about going below 12.3 if you had a NiFe battery. You can go as low as 1.0Volt without longterm damage.

And if you don't have a battery then no worry at all.

Ni-Fe Batteries as per wikipedia "It is a very robust battery which is tolerant of abuse, (overcharge, overdischarge, and short-circuiting) and can have very long life even if so treated."

Using the Wiki as a reference is about as bad as can be. One might use it as a starting point - only.

A great deal of the information in the Wiki is tailored to the last editor's view point.

At the bottom of the page they do provide references - those are useful.

It was more intended as a reference for you to read up on Nickel Iron batteries.

What for? After Mike's experience I have zero interest in them.

If you want to provide a reference - do not use the Wiki - that is only so much BS.

Keep an open mind, just because you know someone that is divorced doesn't mean marriage is bad.

Nickel Iron outlast lead acid batteries by decades.
