Hello All ,
I am in the process of installing backup system at home, i want to backup a usage of 700wh (tv , fridge , wifi )for as long as possible.I have purchased two Pylontech 2.4kwh lithuim ion battery and Goodwe 5048D ES invertor. Grid will power invertor for now. DB about 20m away from where i want to install the invertor.Please advise on cable sizes for grid feed and circuit breaker sizes. Also if i should be vary of anything that i might install now only to have to remove later if i install solar panels. Any diagrams of the layout would be appreciated. I assume that my grid supply would be have a circuit breaker in the db , 20m away i would have another isolator which will feed into the invertor , out of the invertor (should i have a circuit breaker just after ???)into the earth leakage that feeds into the circuit breakers for the appliances
