BD series inverter are designed for single phase grid. Voltage is
220/230/240V, frequency is 50/60Hz. Other technical requests should
comply with the requirement of the local public grid.
Table 4 Cable and Micro-breaker recommended
Micro-breaker should be installed between inverter and grid, any
load should not be connected with inverter directly.
Step4.
Connection Steps:
Step1. Check the grid voltage.
1. Check the grid voltage and compare with the permissive voltage range (Please
refer to technical data).
2. Disconnect the circuit board from all the phases and secure against re-
connection.
Step2. Remove the waterproof lid from the grid port on the
inverter. Step3. Make AC wires.
1. Choose the appropriate wire(Cable size: refer to Table 4).
2. Reserve about 60mm of conductor material sectional area.
3. Remove 10mm of insulation from the end of wire.
4. Separate the docking screw cap of the AC terminal from the housing portion.
5. Insert stripped wires into AC terminal and tighten the screws with a hexagonal
wrench.
6. Tighten the docking screw cap and housing portion of the AC terminal.
Step4. Connect the AC connector to the GRID port of the inverter and
tighten the screw cap .
