I have a customer which want to install first three Quattro 48/15000.
The Batteries are 4 sets of SOPzS Cells with 4350Ah hence 17400Ah @48V in total.
Each Battery Set should get its own BMV 702, appropriated Shunt and 3 Balancers.
Also there will be a 20kW (400V 3P) Windmill on ACout and
DC Coupled at least 6 SmartSolar MPPT 250/100 VE.Can hence 32kWp.
According to "Wiring Unlimited" the Quattos should be connected between the Batteries to equaize the load on the Batteries.
The question is:
Which Power Rail should I use, IF the customer has the intention to add in the comming 2 years 3 or 6 additiional Quattros?
With 3 Quattros under full load I have already 900A, hence I can get with 9 Quattros just 2700A. I have nothing found of this dimension, hence I assume, hat I have to make such PowerRail myself?
My own Batteries are connected to an Aluminium Power Rail of 60x10mm, hence 600sqmm and support without any problems 1000A but 2700A would mean an Aluminium Power Rail of at least 120x20mm because I have from EACH battery set not 1 cable but 4! Hence I need space on the Power Rails for 12 Battery cables (H01N2-E 70sqmm) and for each Inverter 2 Cables of also 70sqmm hence 18 cables. If I use Bolts M10, then I would need a spacing of 30mm and the Power Rail would be around 1m long.
