Contact Us11.5: Batteries
Because galvanic cells can be self-contained and portable, they can be used as batteries and fuel cells. A battery (storage cell) is a galvanic cell (or a series of galvanic cells) that contains all the reactants needed to produce electricity. In contrast, a fuel cell is a galvanic cell that requires a constant external supply of one or more reactants to generate electricity.

Contact UsShould 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.
