4.2 Equipment Installation
4.2.1 Select installation location
1. Check the grid voltage and frequency to see whether it complies with the required voltage and
frequency.
2. Add the breaker or fuse to AC side, the specification should be at least 1.25 times rated AC
output current.
3. The PE cable of the inverter should be connected to the ground. Make sure the impedance of
the neutral wire and the gound cable is less than 10 ohm.
4. Disconnect the breaker or fuse between the inverter and the utility.
5. Connect the inverter to the grid as follows:
There are 3 AC connector brands for inverter, VACONN, WIELAND and Exceedconn.
6. About construction of the AC cable, if the cord slip from its anchorage and place a strain on
conductors, the protective earthing conductor should be the last one to take the strain. So the PE
cable should be longer than L and N.
