Any Pics of a Tunze Battery Power backup setup?

An SLA is about as safe as a battery can get, this is what backups your home alarm, operates a childs Power Wheels toy, and it is what is running any commercial UPS you purchase so they are fairly safe for household use. However, when I was in High School one year my science project was to build an electric car, I used an SLA battery, I had a wiring mishap and the batteries caught fire(I tried 2 in series for more power but it was switched so I could set 12 or 24V and the switch was wired wrong). Nothing is impossible, I would take reasonable precautions to keep them dry and protect the terminals and be sure they are wired correctly, in general as long as you don't short the terminals or wiring, it should be completely safe, but salt creep is a potential cause of a short.
Typical lead acid batteries produce Hydrogen. SLA batteries are completely sealed and vent nothing in normal operating conditions, any water vapor or hydrogen is reabsorbed. Commercial battery cases though are not sealed tight, they only cover the terminals from splashes and exposure.
So a battery box and I should be okay? If I have the battery box on carpet does that matter?
Something I learned in Germany was to always place power supplies and batteries on a piece of tile or stone just in case, if it were to arc, carpet and lint is far more flammable than a piece of stone or tile and scrap pieces are readily available for free from counter top fabricators and tile installers. I would say the risk is low, but I think it is a sensible precaution especially since it generally costs nothing.

Hi there caliking. Did you ever post a pic or brand name of the solar panel you used w/ Tunze safety switch? Looked but can't find it.
