PAV,E

In Germany, P_{AV, E} refers to a set of rules to ensure that feed-in power does not exceed the agreed limit with the grid operator. This requires a certified external protective device that switches off within x seconds if the limit is exceeded. The switch-off time varies depending on the extent of the excess power.
