Grid Connection

The Solar Inverter must be connected to the grid with five-cores (L1, L2, L3, N, PE). We recommend a cable cross-section of 5 x 4 mm2.

The Solar Inverter is connected to the supply grid via its internal printed-circuit board terminals.

As an input-to-grid line protection ele- ment, we recommend using a 3 x 25 A automatic circuit breaker for the NT 10000. No consumers may be connected to the supply line from the Solar Inverter to the automatic circuit breaker. The Solar Inverter injects in three phases via termi- nals L1, L2, and L3. Please mind the pin assignment. A wrong assignment may destroy the device.
