[RE-wrenches] How large is too large?

[Mark Dickson]

The scary thing is they have already pre-approved my
"ballpark-blow-em-out-of-the-water-estimate".  Like Allan mentioned, this is
another common household name. i.e. legitamit customer. . .

What components did you use for the systems in Mexico?

Most likely they will get sticker shock when they see the price, happens to
us a lot. Once that happens you can suggest a more reasonable system,
perhaps grid interactive with battery backup that is a lot smaller.

 

We have done a couple of similar size systems in Mexico, but they had to
grid power within 20 miles or so.

Mark:

I suggest you do not exceed three battery strings, if possible.

Hello Wrenches, 
I have a customer that has really likes the thought of being off-grid and
they have asked me to design a system for their "lodge".  I have kicked and
screamed to get them to consider a grid-tied system using their existing
grid service-to no avail.  
After doing a preliminary load analysis, I have determined that it would
take ~35kW of solar and a couple Bergey Excels for it to work along with a
19,000Ah battery bank.  
So, how big is too big?  If we were to move forward on this, what would be
the major obstacles/show stoppers besides the price (as price is not an
issue)?
What are some of the largest battery based systems that you have installed
or heard of?
Any input is welcome. . .besides being told just to run away from this one.
