Note!
Please refer to the table in 5.4.2 Additionally required materials
to view the recommended wire sizes for GRID, EPS, and GEN.
It is recommended to use copper wire. Non-triple or non-dual
core cables shall be sealed with glue or reproof mud.
When using wire sizes of 6 mm² and above, only 2-core wires
can be used because the 3-core wire cannot pass through the
waterproof terminal. In the case of using 2-core wire, the PE
wire should only be connected to the inverter shell and does not
need to be connected to the internal terminals.
All connection diagrams provided here are based on the use of
a 3-core wire, with X1-HYB-3.0-LV serving as an example.
■ Grid, GEN and EPS connection steps
• Connection requirements
• Connection steps
Check the grid voltage and compare with the voltage range (see 4.Technical
Data for details).
Remember to disconnect all power sources to prevent electric shock.
Step 1. Prepare a Grid cable (Triple core cable), an EPS cable (Triple core
cable) and a GEN cable (Triple core cable), and then nd the Y Terminals in
the accessory bag. (Taking X1-HYB-3.0-LV as an example)
