I am harvesting more cells when I get time, and now starting to test with an Opus BT-C3100.I want to move onto the planning/design phase, but need some thoughts/help with the plans and ideas I'm having for it.
My plan is to build a pack for camping and emergencies in a wheeled, waterproof plastic case. Would like the designto be modular, and expandable, so as I harvest more cells, I can expand the overall pack. Want it 7S for 24V. Was planning 10P per individual pack, as would be about 500Wh per individual pack, but it would depend on the size of the case. Would like to try get at least 2kWh overall.
How hard would it be to build modular 7S packs, so that as I get enough cells for another individualpack, I can add as another parallel to the existing setup? I do want these to be safe as well, so they are not moving about in the case, preferably held securely in place, and not at risk of shorting out with something else in the case.
Would I be best to run 1 BMS per individualpack as built, or get something so that I can have 1 BMS overall, and plug it into each individual pack as I build them? I am aware of batrium, but it is too expensive IMO for what I am building.
For power, I plan on having 100-150W solar panel, running through an MPT-7210A. And be able to add more panels if needs be. But also chargeable from an adapter from the wall.
I would like to mount the inverterinside the case too, and waterproof outlets on the side of the case, or would this be pushing it too far for heat or safety?
I am happy to fabricate stuff, and buy a small 3D printer if need to make some plastic parts.
