So now the top of the battery was clear, however I had added items onto the battery in a hodge podge manner and had wires entering the battery on 3 sides.
So I took to opportunity to improve this by both increasing wire sizes and moving all entry into the box to the rear of the battery on a separate panel.
I also changed out the couloumeter to a Junctek KM110F which has wireless, so I can view the battery condition anywhere.
This is what it looks like now.
Everything seemed to be working well, and I was getting ready to install 6 more battery packs on the top of my battery, when the inverter popped.
I was in the basement at the time, and there was no change in noise level or anything, just the breakers on the batteries and inverter tripped. It was in the middle of the day, so there would not have been much of a load on the inverter.
In testing I can only find that Q5-Q8 and Q13-Q16 have failed. The little power supplies and driver transistors are ok. I am thinking of using my back up board as replacement rather than fixing this one.. I can't see any other issues at this point. Thoughts on what else to check?
thanks
