Here's where it is:

I have 14kw in panels and 40kwh in batteries. I'm running lead acid batteries, because sometimes you have to buy what's available and understood by local suppliers and maintenance people. My electronics are from Outback Power.
Batteries are just awful. They are the single most expensive part of an off grid setup. They have a half life and need to be replaced. We have found a program from the federal government to bring power into rural areas, like ours, and have a meeting setup in two months. Hopefully we qualify for that and will get utility power sometime this year. If so, Mexico currently does net metering, which would mean that my panels will be able to bank tons of credits pushing power into the grid and the grid will act as a perfectly lossless battery.
