Step 1: Grid String Connection
AX series inverters are designed for three-phase grid. Per voltage range is
220/230/240V; frequency is 50/60Hz. Other technical requests should comply
with the requirement of the local public grid.
Model (kW)
Cable (ON-GRID) (mm²)
Cable (EPS) (mm²)
Micro-Breaker (A)

A micro-breaker for max output overcurrent protection device
shall be installed between inverter and grid, and the current of the
protection device is referred to the table above, any load SHOULD NOT
be connected with the inverter directly.
Step 2: Grid Wiring
• Check the grid voltage and compare with the permitted voltage range
(refer to technical data).
• Disconnect the circuit-breaker from all the phases and secure against
re-connection.
• Trim the wires:
