No output or will not start
Dead or tripping on start-up: we test the auxiliary supply, control board and power stage separately.

SMA solar inverter repair in India
Star Automations repairs SMA 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
SMA inverter faults we repair
SMA string and central inverters are found on older and newer plants across the country. Each area is tested on its own, so a fault in one part does not become a full board swap by default.
Isolation and earth-fault trips
Nuisance isolation or RCMU trips: the sensing circuit and its supply are tested with the insulation circuit intact.
Grid fault and relay faults
Grid relays, voltage and current sensing, and the connections to the control board.
Overheating and fan faults
Fan-drive circuits, thermal sensors and power-stage heat damage.
DC input and MPPT faults
DC input stage, MPPT sensing and the boost circuit.
Display and communication faults
Display and keypad boards, communication and monitoring boards.
02Models
SMA 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.
- Sunny Tripower string inverters
- Sunny Boy residential inverters
- Sunny Central inverters for utility plants
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 SMA 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 SMA 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 SMA units
Do you repair SMA solar inverters in India?
Yes. Star Automations repairs SMA 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 SMA?
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 SMA 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. no output or will not start, isolation and earth-fault trips, grid fault and relay faults are typical starting points. We send the findings before any part is replaced.
Do you train O&M teams on SMA 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 SMA units your team runs. See the solar O&M training page for the modules.
How do I send a SMA 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 SMA 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 SMA 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.
