Single or dual pole breaker between pv array and mppt on a grounded ...

On my case, as per regulation, the negative needs to be grounded. If you interrupt the negative of the PV, that wire won''t be grounded anymore, as the Victron solar panels are of isolated ground type (connection between negative and ground on a boat happens in one point, and that''s generally on the main negative busbar).

Why to disconnect the negative/ground terminal, not positive?

If one side of a supply is grounded, you switch the other one. If neither side is grounded, you double pole switch both. If it''s a three rail DC supply you''d either switch the two outers (grounded) or all three poles (isolated). Switching goes on the side that will render the circuit beyond the switch safest in the off position.

In this schema, does ground just mean that the negative poles should be connected?
