1. Measure and access the voltage and frequency of the point to ensure that it meets the grid-tied
specifications of the inverter.
2. PE wire(GND) must be well grounded to ensure that impedance between Neutral wire and Earth wire
be less than 10Ω.
3. Disconnect the circuit breaker or fuse from the inverter and grid-connected access point.
4. Use the copper wire.

2
Wires threading and pressing.
(Only take PV 25KTL-D3/G2 model as an example)
3
Lock the AC cable to the corresponding AC terminals.
The RCD used on the main solar supply circuit should be Type A 100mA. This and all associated wiring
must be installed in accordance with AS /NZS 4777.1
