Should neutrals be tied together or left separate?
When ON, there appears to be about a 30VAC difference between the "battery output" Line pins and the input cable''s Line pin. Same with the Neutral pins. FYI the panel is hard-wired into the mains, so there''s no chance the user would plug the cable in backward, thus placing 120VAC on the neutral wire.
Ground or earth provides a common return path for electric current in an electric circuit. It is created by connecting the neutral point of an installation to the general mass of the earth or a chassis. Grounding is needed for electric safety and it also creates a reference
