Item Description Remark
A AC circuit breaker
Used as a protective device during electrical
connection. User equips this device according to
the maximum output voltage and current.
B Utility grid
Nominal line-to-neutral voltage of the utility grid is
230V.
C SolarInfo WiFi It is used for wireless communication.
D PV arrays
-S series: one input area with one pair of terminals.
-D series: two input areas with two pairs of
terminals.
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.
