i know its wrong, also its weird when we connect the solar power (without connecting to circuit around 14 voltage) however when we connect it to circuit it it doesn't show any voltage.
i need your help for this home project to do show us how to connect it

step by step.

and make new circuit to switch between two input
the idea is we have grid power (120V AC) and battery power after converting to (120 V AC)
when the battery power goes low, it automatic switch to grid power without disturbing
