The reverse power relay is a directional protective relay that prevents power from flowing in the reverse direction. The relay is used in installations where a generator runs in parallel with the utility or another generator so as to prevent power from the bus bar or another generator from flowing back to the active generator when its output fails.
The reverse power relay is a fail-safe in case this power controller doesn''t work. You meter the net load of your site''s service, or another metering setup that would add up to the net load of your site''s service.
