Good day, We got a 8KW Deye invertor, 16 x 535w JA Pannels and 6 x Shoto Lithium Batteries. We are installing a second 8KW inverter with 16 x pannels, Inverters will be connected parralell and adding another 4 Shoto batteries. Batteries connected to a bus bar. What size Battery cable must I run from the bus bar to the invertors? And what AC cable size from inverters to DB? DB is 45m from invertors.
