5.4 Connecting Inverter to AC Grid

The inverter is connected to the grid via 3 wires (L, N, and PE). Feeding power is
always single-phase via AC terminal at the bottom of the unit.
An appropriately sized AC circuit breaker is suggested as the protection equipment
in AC connection, as shown in Fig. 5-2.

5.4.1 AC Side Requirements

Only after being approved by the local grid company can you connect
the inverter to the grid.
Prior to connecting the inverter to the utility grid, verify whether the grid voltage
and frequency are within the range of inverter output parameters (refer to
Appendix). Consult the local grid company for solution if otherwise.
