Grid-connected systems vs. microgrids — what''s the difference?
1. Dependence on the main grid: Grid-connected systems still rely on the main grid as their primary source of power. They need to draw electricity from the grid to operate, so they can''t operate autonomously during grid outages. 2. One-way power flow: Grid-connected systems typically have a one-way power flow, where electricity flows

Depending on which connection point we are going to use, there are different German standards for grid connection: VDE 4105 for low voltage, VDE 4110 for medium voltage, VDE 4120 for high voltage and VDE 4130 for very high voltage. There are also specific procedures for testing, simulating and certifying, which are TR3, TR4 and TR8.
