Hitachi Hi-Rel solar inverter repair in India
Star Automations repairs Hitachi Hi-Rel 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.
01Repair
Hitachi Hi-Rel inverter faults we repair
Hitachi Hi-Rel solar inverters run on commercial and utility plants. Each area is tested on its own, so a fault in one part does not become a full board swap by default.
DC contactor and protection
Contactors, fuses, surge protection and DC-side sensing.
Cabinet cooling and fans
Cooling-fan drives, thermal sensing and heat-damaged parts.
Control and auxiliary supply
Control board, DSP supply, auxiliary SMPS and sensing inputs.
Grid interface and protection
Grid-side sensing, relays and protection circuits.
Communication and SCADA interface
Communication boards, interface cards and operator panels.
02Models
Hitachi Hi-Rel models and series
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.
- Hitachi Hi-Rel solar inverters and power conditioners
- Control boards, driver boards and power stacks
03Process
From diagnosis to report, in five steps
Findings come before repair, so you decide with the facts in front of you.
Inward and nameplate log
Serial number, nameplate and fault history logged, with photos of the unit before any work.
Diagnosis
Fault codes, power and insulation checks, auxiliary supply tests and inspection of the power stage and control board.
Quote with findings
The faulty part, the likely cause and the repair options, before any part is replaced.
Repair and functional check
Failed components replaced with parts from established distributors, then a power-up and functional check on the functions the fault affected.
Report and dispatch
Printed report with findings, parts replaced, test readings and sign-off, sent back with the unit.
Safety first
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.
How Hitachi Hi-Rel inverter boards are tested on our bench
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.
04Training
Training for your Hitachi Hi-Rel O&M team
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.
- Safety and isolation, field diagnostics, power stage, control and auxiliary circuits
- Bench lab on faulty units, with findings written in our report format
- On site, at our Puducherry factory, or hybrid
- Models agreed in a scope call, so the syllabus matches your Hitachi Hi-Rel units
05Questions
Hitachi Hi-Rel inverter repair questions
More on the solar inverter repair page and the FAQ page.
Do you repair Hitachi Hi-Rel solar inverters in India?
Yes. Star Automations repairs Hitachi Hi-Rel 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.
Is Star Automations an OEM service centre for Hitachi Hi-Rel?
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.
What Hitachi Hi-Rel inverter faults can you repair?
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.
Do you train O&M teams on Hitachi Hi-Rel inverters?
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 Hitachi Hi-Rel units your team runs. See the solar O&M training page for the modules.
How do I send a Hitachi Hi-Rel inverter for repair?
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.
How long does Hitachi Hi-Rel inverter repair take?
The time depends on the fault and on part availability. We give the timeline with the quote, after the diagnosis findings.
Do you offer a free evaluation for Hitachi Hi-Rel inverters?
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.
