Battery Back-Up

February 3, 2010

Battery Bank before the Upgrade

When I ordered my batteries for the solar system the company recommended that I use a 48 volt setup. I then purchased eight 105 amp AGM 6 volt batteries and connected them in series. A few weeks later we decided to get a second identical setup and connect them in parallel. This configuration still gave me 48 volts but with twice the amperage.

I had originally put a “Battery Room” next to the “Electrical Room” (as pictured) and vented it for safety.  As it turned out, the AGM glass mat gel batteries do not “off-gas” which means that I could have put them anywhere I wanted. We still put them in the Battery room and now also store the backup 3500 watt Champion generator in there as well.

More on the primary Guardian Whole House Generator later.
