The stackable battery systems sound like an easy way to expand the system if needed. Does the inverter get hotter as it is mounted on top of the batteries, or do the batteries run cool all the time? Hi Pete, I'll never move away from tinkering with electronics its a part of my DNA. I have a number of quality old school VCR/DVD players, speaker-boxes, direct drive turntables, Amplifiers to refurbish/repair that I may never actually finish them all, plus a heap of inverters commercial and home-made, whose future has not yet been determined, along with an ever-growing number of inverter toroids, ring chokes enclosures heatsinks. In an earlier life when money was tighter I found it easy to accumulate but hard to throw stuff out, breaking old habits doesn't always come easy. My wife keeps on pointing out that my workshop is beginning to look like Steptoes junk yard lol. I am now going to begin a cull of things, keeping only the really good stuff. I also have a plan to complete a benchtop switch-mode power supply design I started to design at the beginning of the inverter project. Its requirement was at least 60V @ 25A I have all the boards etc ready for assembly gathering dust for 4+ years. The batteries all seem to from run mildly warm on a pleasant day to very warm on a hot day.  The inverter/MPPT charger module (on top) runs at least 20 degrees above ambient most of the time, I'm sure the already warmer battery modules don't help.
