Ring Final Circuit Diagram

A ring final circuit diagram can be made up of several different sections, including a main earth point, the live and neutral supply, along with the load circuits and the control switch. It is essential to ensure that these components are connected correctly, and that all safety precautions have been met before attempting to install the system yourself.

Solar Panel Wiring Diagram and Installation Tutorials

I am not sure why you said 2pcs of 120ah12V battries in series. He needs batteres to supply the 1500w loads for 12hours at night. Basically that is 1500w * 12 = 18000wh. dividing by 50% depth of discharge as you choose flooded, that is 18000/0.5=36000wh or divde by 0.8 if for AGM batteries, that is 18000/0.8 = 22500wh.
