6.2 Grid Connection
X3-Hybrid series inverter are designed for three phase grid. Voltage is 380/400V,
frequency is 50/60Hz. Other technical requests should comply with the
requirement of the local public grid.
Micro-breaker should be installed between inverter and grid, any load should
not be connected with inverter directly.
Table 4 Cable and Micro-breaker recommended
Connection Steps:
Step1. Check the grid voltage.
1.1 Check the grid voltage and compare with the permissive voltage range
(Please refer to technical data).
1.2 Disconnect the circuit-breaker from all the phases and secure against re-
connection.
Step2. Remove the down-top cover from the inverter.
Step3. Make AC wires.
3.1 Choose the appropriate wire(Cable size: refer to Table 4).
3.2 Reserve about 60mm of conductor material sectional area.
3.3 Remove 12mm of insulation from the end of wire.
3.4 Insert stripped wires into AC terminal and insure all conductor strands are
captured in the AC terminal.
3.5 Compress the AC terminal head by using a crimping pliers and screw down
screw cap tightly.
Step4. Insert AC cable into Grid port through screw cap and then tighten the
screw cap. Insert L1,L2,L3 wire and N wire into corresponding ports of AC
terminal.Compress the PE wire with earth terminal , then screw it on the
grounding stud.
