The configuration depends on the size of the battery bank. If you gonna run 50kW continously thats ALOT! That would potentially need more than 1000 cells in paralell. We are talking about 14 000 cells!
Imaging making 80p packs out of that. I would make 14s250p or something atleast. Just beware of the BMS so it can handle and can balance it withincertain time-frame.
Hi Daromer
Thats a lot of cells yes but actually my vision from the outset was to try and use a lot of recycled cellsBefore Looking to introduce new cells into my packs. Im a long way off! haha I have designed a fake wall 8m in length, 3m High, and 2m in width completely external to the house to house all the batteries, inverters, mppt units, etc so I have the space! haha
So Looking to deal with 50Kw in a way that makes sense. 50kw was a figure forecast by turning everything on this house I am building on to the max! Heating raging! Ovens, induction Hobs, Microwave, Toaster, Kettle, Coffee Machines, fridge and freezing running at max,Washing Machines, Tumble Dryers, Iron, Water Heating backup, towel radiators, Water Pumps,TVs, radio, interior and exterior lights, tool li-on batteries charging, laptops, nas, smart home bits, inverters, and 1 electric car charging in this scenariono wind or solar its christmas day and the demand for turkey on the table wins over common sense.
The likely chance of all these happening is unlikely. This would be a worse case scenario.
So Logically thinking using the inverter spec I foresee at the end 5 inverters, 5 Battery Banks, Banks will be min of 1s8p consisting of Packs of 14s80p taking your advice of increasing the capacity.
If for example I achieve this is over the next 2 years My Powerwall hopefully will be around 560Kwh on paper but usable around450kwh. I will be hoping to charge multiple electric vehicles and utilizing around 45000 used cells.
The crazy thing is this sounds a lot. I am looking to never pay an energy company again but instead invest in my own personal energy company. This is a house for life. Hence why my KW is so high. So Taking all of that in do you think Im now getting the right spec or does someone have a better plan? I am open to any suggestion if someone has it using this info?
Cheers
