📝 Description

Used product. Three-phase inductor assembly intended, according to the available identification, for the AC output filtering section of ABB / Power-One Aurora photovoltaic inverters.
The component consists of three coils wound around magnetic cores, mounted on a metal support and complete with wiring, pin terminals and a screw terminal block. The connections are marked R, S and T, corresponding to the three phases of the circuit.
The assembly is associated with the AC filtering section of Aurora PVI-10.0 and PVI-12.5-TL-OUTD inverter families. In this section, the inductive components help filter the output current before the energy is fed into the electrical grid. ABB documentation illustrates the line filter and grid-parallel relay within the inverter architecture.
The exact function and compatibility with individual revisions must be confirmed using the replacement part number and by comparing the component with the original. The associated board code, 3G83 Pb-Free, and references to errors E030, E031, E032 and W003 must be verified for the specific model and do not constitute a definitive fault diagnosis.

⚡ Role Within the Inverter

In three-phase Aurora photovoltaic inverters, the energy generated by the panels is converted from direct current (DC) to alternating current (AC). The AC filtering section helps condition the current before connection to the electrical grid.
The pictured assembly is identified as an inductive component of this section. Its exact position in the circuit and its association with the filter and relay board must be verified against the relevant inverter revision.

🧩 Compatibility

Compatibility to be verified for:

• ABB / Power-One Aurora PVI-10.0-TL-OUTD.
• ABB / Power-One Aurora PVI-12.5-TL-OUTD.
• Other family variants, only after comparing the part number and original configuration.
  Compatibility must not automatically be extended to all -S and -FS versions or to other Aurora inverters.

🛠️ Applications

• Repair of three-phase photovoltaic inverters.
• Maintenance of the AC output section.
• Replacement of damaged inductor assemblies.
• Recovery of spare parts for compatible ABB / Power-One Aurora equipment.
