Hello
So thought I would concentrate on one thing this evening. Figuring out how I should connect my cells together.
Without getting in to deep I've watch a lot of video's and left undecided on how I should do my series and parallel configuration.
So keeping this simple my powerwall will be an ever increasing design in capacity. Picture 4 server cabs if you will and Im starting on the first 3u tray.
I am to achieve 48-60v for my inverter. Now for simplicity should I say go 15s16p per pack to utilise the easily available 4x5 cell holders out on the market and should see around 63v-45v as the pack is used. For me I can see a plus side that I could remove a pack from wall to periodically check and all I would do is alter the capacity.
Or is this a bad idea. is there a con with this and something like asmaller series a better idea say 7s74p and except that everything is done in pairs because of some pro's that I haven't considered?
Would you recommend lower voltages for safety? Also thinking about the potential of a completely off grid house would it be in my interest to increase safety measure when handling and increase the voltage for potential kw output.
I have realised that Batrium is looking a must so not really understanding how all their products work would I be ruling say longmons out with a 15s16p as if I read right the range is up to 5.4v? Which means maybe I go 1s80p like I've seen done and except I work in groups of 15 to achieve my desired voltage?
As always any input is honestly well recieved as just trying to get my design right with minimum mess up's.
thanks
