11.2. AC Line Reactors
An AC line reactor can be used for any of the following:
- Capacity of power system is much larger than the inverter rating.
- Inverter mounted close to the power system (in 33ft / 10 meters).
- Reduce harmonic contribution (improve power factor) back to the power line.
- Protect inverter input diode front-end by reducing short-circuit current.
- Minimize overvoltage trips due to voltage transients.
Please select the AC line reactor based on the inverter
overload according to the following table.

Note: AC reactors listed in this table can only be used for the inverter input side. Do not connect AC reactor to the inverter
output side.
(*) 400V class 75kW ~ 160kW have a built-in DC reactors. If required by the application an AC reactor may be added.
