Two tiers -- back tier higher and made of wood; lower tier sitting on a
concrete floor -- in a specially built room in the garage; enclosed in a
plywood box lined with neoprene to contain any spills.
Handling -- it was during house construction and we had three very husky
carpenters. I don't know what I'll do when the time comes to change them
:-((.
Regrets -- I should have made the room a bit larger, and provided better
ventilation. The batteries themselves get a little warm; but I have the
inverters in the same room (not in a position where they will be affected
by battery fumes). The inverters also include battery chargers, and when
that is running quite a bit of heat is generated.

Nailed to the wall in the adjacent garage.

E-Meter for the battery bank; and the stuff that's included in my Trace
SW5548's and Outback MX60. The controlling is essentially automatic;
including automatic generator control. I've even got a relay that turns on
the generator engine block heater at the appropriate time. I do have to
remember to plug that in in November or so; and unplug it in the Spring.

No. But some say separate DC is good for back up in case your inverters go
TU.

Attached garage.

I'm new to the game, and I've already found that I don't need the capacity I
originally planned. The lighting is all low-voltage, the
heating/cooking/refrigeration is all gas, and the only things I need AC for
are the electronics, such as cellphones, TV, satellite, DVD and microwave.
These are easily powered by several small inverters and one 2000W, which is
only switched on as needed. Two 100W PV panels provide ample charging of
the 4x 225 AH batteries. Frills like air conditioning, power tools if
needed could be easily powered by a generator.

Refering to air conditioning as a "frill".
