Star Automations repairs Power Electronics solar inverters at component level at its factory in Puducherry, for owners, EPC contractors and O&M teams across India. We find the failed part, repair it, test the unit and return it with a report. We also train O&M technicians on inverter fault-finding. Star Automations is an independent multi-brand repair company and is not an OEM service centre.
Power Electronics central inverters run on utility-scale solar plants. Each area is tested on its own, so a fault in one part does not become a full board swap by default.
Failed IGBT modules, gate drivers, bus-bar and snubber circuits.
Contactors, fuses, surge protection and DC-side sensing.
Cooling-fan drives, thermal sensing and heat-damaged parts.
Control board, DSP supply, auxiliary SMPS and sensing inputs.
Grid-side sensing, relays and protection circuits.
Communication boards, interface cards and operator panels.
Send the model and a nameplate photo and we confirm the part route before you ship. Scope depends on the model and on the parts we can source.
Findings come before repair, so you decide with the facts in front of you.
Serial number, nameplate and fault history logged, with photos of the unit before any work.
Fault codes, power and insulation checks, auxiliary supply tests and inspection of the power stage and control board.
The faulty part, the likely cause and the repair options, before any part is replaced.
Failed components replaced with parts from established distributors, then a power-up and functional check on the functions the fault affected.
Printed report with findings, parts replaced, test readings and sign-off, sent back with the unit.
Inverter DC-link and mains circuits can hold dangerous energy after power is removed. Please send units de-energised and disconnected from the site. We verify isolation and discharge before handling.
Each fault is traced section by section on our functional test system, then the repaired unit gets a power-up and functional check before it is returned with a report.

Hands-on solar O&M training at the bench, on real faulty units, so technicians learn to find the failed component instead of swapping a board.

Yes. Star Automations repairs Power Electronics inverter electronics at component level at its refurbishment factory in Puducherry, and accepts units shipped from anywhere in India. Scope depends on the model and on the parts we can source, so send the model and a nameplate photo and we confirm the part route before you ship.
No. Star Automations is an independent multi-brand repair company and is not an OEM service centre. Warranty decisions stay with the OEM or your EPC, and our report gives you the findings to take to them.
We trace faults to the failed part in the power stage, the control board, the auxiliary supply, the protection and sensing circuits, and the display or communication boards. power module and igbt stack, dc contactor and protection, cabinet cooling and fans are typical starting points. We send the findings before any part is replaced.
Yes. We run hands-on solar O&M training on inverter fault-finding, isolation and bench work. We confirm the models during the scope call so the syllabus matches the Power Electronics units your team runs. See the solar O&M training page for the modules.
Send the model, serial number, a nameplate photo, the fault codes and a short fault history on WhatsApp at +91 97866 22233 or through the RFQ form. Units should be sent de-energised and disconnected from the site. We reply with what we can do and the packing guidance.
The time depends on the fault and on part availability. We give the timeline with the quote, after the diagnosis findings.
Yes. Send a nameplate photo, the fault codes and a short history for a free board evaluation. We reply with the section we think is faulty and whether component-level repair is practical for that unit.
