The delivery guys arrived at 10AM to exchange the old ones; they were kind enough to place the new ones back on the shelves, except for the four new ones since the shelving was not ready for them. I had to cut a carpet scrap first to make a pad to protect the bottoms from the wire shelves.
The next couple of hours was all about reconecting all the interconnects and torquing the bolts carefully lest I break a terminal seal. I had to fabricate a new set of main cables for the new battery bank set and solder on terminal lugs. Soldering a 3/4 inch diameter lug onto #0000 welding wire is quite interesting. It takes a propane torch, a lot of solder, and much patience.
The results are wonderful! Even though I got bank 5 up at 4:30PM, which meant it did not get fully charged, the voltage levels are excellent. Massive amounts of lighting, a fullly loaded dish washer running at 180F sanitizing setting, a hot water urn, and other heavy usage that would have kicked on the generator at 8PM is proving to be completely handled by the energy stored during the day!
I forgot how much energy a fresh set of batteries can store, and it was quite insidious how over the 6 years the loss of caapcity crept in. We were just getting used to the ever so slightly drop in power. Now we have 31KWH at 50% DOD. Well, I'm heading off to the hot tub to enjoy the success of this day and to soothe the sore muscles. Tomorrow is day two of Soul Collage.
