Hello Battery Wrenches,
Over the years I have had several battery banks in Baja and Sonora Mexico fail
in just 36 to 48 months. These have been L16 or 8D AGM or flooded banks, 24 and
48 volt systems. The charging systems are working properly and programmed to
manufacturer recommended set

If my memory serves me correctly
(and that is a big if) I recall tropical locations sometimes install
batteries with slightly a weaker electrolyte solution. Maybe Jamie can
chime in on this.

Hi Todd,
You are correct. Sometimes as low as 1.220 to offset heat but generally
1.240.

Are you using temperature compensation? It lowers the voltage when its hot.
Also, have you considered setting the batteries in a below ground vault? I've
had good luck with in floor battery boxes.
Finally, AGMs and L16s just don't last very long anyway. AGMs maybe 3 years,
and L16s I've seen die

I'm proposing a PV array on a metal building with L feet attached directly
thru the roof into the purlins. The plan is to use thread cutting SS bolts,
a minimum of ΒΌ-28 pitch. The metal is 14 ga and will engage over 2 full
threads and because the array is only 2 landscape modules on NS
Generally, in order to develope the full tensil strength of the bolt, it
should be engaged by a minimum of 5 threads.

Hi Larry,
Are you installing them ground coupled or insulated off the ground?
I've found that by keeping them on the dirt so to speak, will keep them lots
cooler.
Another trick for the desert is to build a well insulated box, and have a fan
run at night using a differential thermostat ,
