Blackout / Overload Protection

From software version 3.07.10

The settings in the inverter for overload protection are designed to prevent the main fuse at the grid connection point from tripping.

The rated current of the main fuse is configured within the inverter. This prevents the grid connection point from becoming overloaded, for example, when an EV is being charged via an ENECTOR G2 wallbox. The EV charging current is reduced at an early stage by the MDC control system or set to zero.

In the case of a 3-phase grid connection, the grid connection has 3 main fuses. In the case of a 1-phase grid connection, there is, accordingly, only one main fuse. The rated current of each fuse can be read off the fuse itself.

Under the menu item Service > General > Grid Connection > Overload Protection, the value for the rated current of the main fuse must be set correctly. If the set value is greater than the actual value of the fuse, protection against overload of the main fuse cannot be guaranteed.
