Hi All
My First post here, so hello to all.
Bit of background to start, i have been fortunate enough to get hold of a complete Tesla P85 battery - 16 modules.
I have a small holding, which has a small campsite with 3 16a hookups, my wife has a cattery which during the winter has electric heaters going 24/7, outbuildings that have various loads eg. welding, air compressors, and then our house with general stuff,eg fridge freezer, tv and lastly the big one, a 10kw shower. With all these loads the peak seems to be at or around 13/14kw for around 10/15mins (Its the shower !!!).
Im connected to the grid (3 phase), and would like to use that as and when the solar/battery is not capable of the supply.
I had thoughts on what i want, but want to asksome advice, thoughts on the best approach.
One approach is to connect the shower to one phase,and just take that out of the equation,and then run the solar/battery and use the connection to the inverter to one of the phases as the backup reducing the peak load on the inverter to more like 4 kw.
So one concernis with the inverter, and the other is with the BMS.
Option one.
Using a sigineer 15kwh inverter that has been made to cope with Tesla batteries, and a costly BMS by evtv. But the inverter has a 50 day wait at the moment, and then its got to be shipped from chine, so more time. Not thought what MPPT charge controller i would use, but expect it would bevictron.
Option 2
Using a complete victron setup - 15kwh invertor, cerbo GX, bluesolar 120/100 smart charge, victron shunt 500A 50mV, lynx dist board.
BMS is the concern with this setup, can go with the simp BMS, which uses existing tesla slaves, (But lots of build time) or using a Batrium wm5 and swapping out the slaves.
Option 3
using all option 2 but swapping the 15kwh inverter to a 5kwh
So this is where you lot come in, what setup route would you go orwould you suggest anything different/better?
Many thanks in advance.
