GRID CONNECTION AND EPS CONNECTION
Hybrid 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.
Micro-breaker should be installed between inverter and grid, any load should not be
connected with inverter directly.
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 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 and EPS wires.
3.1 Choose the appropriate wire(Cable size: refer to Table 1).
3.2 Reserve about 60mm of conductor material sectional area and remove 10mm of
insulation from the end of wire.
terminal and tighten the screws with a hexagonal wrench.
3.3 Separate the docking screw cap of the AC terminal from the housing portion and insert
stripped wires into AC
3.4 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 .
Connect the LOAD connector to the EPS port of the inverter and tighten the screw cap .
