The Outhouse Powerwall
#45
So more details on the XW+6848... I picked it up locally for $1500 and is a 48v unit. Quite a monster and heavy too. It's at 6800W unit and is able to run 6000W at 40C continous, which is what my max temp during summers would be. Most inverters would derate more than that. It's overkill for my use but will be nice to swap. So I will take my time and do some comparisons between my 24v system and then after the switch. I have to do some rewiring because I only wired for 120V and I'm going to go 240V. This unit doesn't have the autotransformer built in like the smaller SW sibling, so it's unable to take multiple inputs, so it can't have 120V in and have 240V out, so I have to redo my wiring to the mains. This will be a project for the summer!

In the meantime, I've had these Headways LiFe cells that I bought a while back, and finally had a chance to use them when I had a flat tire on my car and had to use my bike last month. Good idea, but one problem... damn battery on the bike was dead again! This is probably the 4th battery in this bike and I was just tired of replacing it. So I remembered the Headway cells and this time I rigged four of those batteries and it was able to crank away until I got the bike started! Didn't even flinch! Still need to make a more permanent case for it, but for now it's awesome!


Also a friend wanted a 6V battery for his engine and for that I am using a harbor freight case for more protection. I made a 3d printed holder that allowed me to use 1/2" copper pipe as the bus bar. I calculated the pipe to be around 4AWG, which should be just enough for the short burst up to 600A. Perfect fit in the case with just barely enough room for the terminals. Still need some measurements to finalize the hole locations but it looks like it is going to work out well.
