Pardon me.  I missed the comment about battery load calcs.  In the 24 years I
installed professionally, I did hundreds of my own installations and countless
more takeovers.  With the exception of a few extremely large systems that I did,
every professional installation in a residence that I ever saw had either a
single 12 Volt x 4 Amp Hour or 12 Volt x 7 Amp Hour battery.  Not one
professional installer does battery load calcs on residential systems.  What I
did notice was that *most* systems installed by the larger companies and *all*
systems installed by the so-called "authorized dealers" were underpowered, using
the smallest, cheapest battery they could find.  I've actually found panels with
1.2 Amp Hour batteries in them.

So tell me how hiring a professional installer is going to improve on telling
the customer to use a 7 Amp Hour battery?

Just to clarify things, if the DIY client happens to have an exceptionally large
home or the system will have more than a few keypads, I often instruct them to
get either an extra battery, wired in parallel  or an auxiliary power supply.
