SMA Product Lines We Repair
Our engineers are trained on the full SMA product range. Below are the major product families we service.
Sunny Boy (SB) — Residential and Commercial String Inverters
Single-phase and three-phase string inverters (3 kW to 12 kW) for rooftop solar. Common repairs: IGBT module failures, input contactor wear, DC surge suppression faults, and firmware corruption from grid transients.
Sunny Tripower (STP) — Three-Phase Commercial Inverters
Three-phase inverters (8 kW to 25 kW) for commercial rooftops and small industrial facilities. Typical faults: electrolytic capacitor drying, IGBT short-circuits, isolation transformer winding faults, and Ethernet communication module failures.
Sunny Central (SC) — Utility and Industrial Three-Phase Inverters
Mega-watt class central inverters (250 kW to 630 kW) for utility solar farms and large industrial complexes. Repairs include: AC contactor failures, DC bus voltage imbalance, cooling fan motor burnout, and capacitor bank rejuvenation.
Sunny Island (SI) — Battery-Coupled and Hybrid Inverters
Hybrid and battery-backup inverters (3 kW to 10 kW AC-coupled) for off-grid and UPS applications. Common issues: DC contactor arcing, battery charger section failures, load transfer relay sticking, and BMS communication faults.
SMA Control and Monitoring Systems (SMArg, Sunny Portal, Modbus RTU)
Integrated control modules, display cards, and remote monitoring interfaces used across all SMA inverters. Faults: SD card corruption, Modbus communication timeouts, LCD backlight failure, and gateway module RF signal loss.

Common SMA Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in SMA equipment arriving at our workshop.
- ✓IGBT module thermal runaway and short-circuit — SMA inverters experience IGBT gate-drive failures due to harsh Indian summer ambient temperatures (45-50°C) and poor heat dissipation in dust-heavy industrial environments. Repeated thermal cycling degrades solder joints on power modules.
- ✓DC-link electrolytic capacitor drying and voltage instability — SMA inverters operating 10+ years in tropical Indian climates experience electrolyte evaporation. High ripple currents from grid harmonics accelerate capacitor ESR rise, causing voltage sag and inverter de-rating below rated output.
- ✓AC contactor chatter and intermittent grid disconnect — SMA three-phase inverters use AC contactors for grid isolation. Burnt contacts, stuck armatures, or insufficient holding coil voltage (common during Indian grid brown-outs) cause nuisance de-rating or complete inverter lockout.
- ✓Firmware corruption and boot-loader timeout errors — Indian industrial sites experience frequent power cuts, grid spikes, and lightning strikes that corrupt SMA inverter firmware during updates or runtime. Failed firmware results in boot-loop, factory reset loops, or complete inverter unavailability.
- ✓Ethernet and Modbus RTU communication module failures — SMA Sunny Portal gateways and Modbus RTU interfaces suffer from corroded RJ45 connectors, ESD damage, and phantom voltage from improperly installed lightning arrestors on data lines in Indian industrial setups.
- ✓Cooling fan motor burnout and thermal shutdown — SMA inverters in Indian foundries, textile mills, and food processing plants accumulate conductive dust on heat sinks, reducing cooling efficiency. Fan motors overheat and fail, triggering thermal de-rating or complete shutdown in summer.

Frequently Asked Questions — SMA Repairs
Do you repair SMA inverters anywhere in India?+
Yes. Synchronics repairs the complete SMA inverter range — Sunny Boy, Sunny Tripower, Sunny Central, and Sunny Island series across all capacities. We offer pan-India door pickup from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Kolkata, and 50+ cities. All repairs are performed in our Vadodara, Gujarat facility by engineers trained on SMA diagnostic tools. Turnaround time is typically 5-8 business days.
My SMA Sunny Tripower shows E_BAT or E_DCI error codes. Can you fix this remotely?+
SMA error codes like E_BAT (battery low), E_DCI (DC injection fault), and E_GRI (grid failure) are often caused by firmware version mismatches, failed sensors, or capacitor-bank voltage sag. Synchronics can diagnose via remote Sunny Portal data export, but physical repair requires unit inspection. We recommend shipping to our facility for IGBT testing, capacitor ESR measurement, and firmware re-flash under controlled conditions.
What is your warranty on SMA inverter repairs?+
Synchronics provides 12 months' parts warranty and 6 months' labour warranty on all SMA repairs. We use genuine SMA and OEM-equivalent capacitors, contactors, and power modules. If a repaired unit fails within warranty due to our workmanship, we repair or replace at no cost. For critical industrial installations, we offer extended 24-month warranty on electrolytic capacitors due to India's harsh thermal environment.
Can Synchronics repair SMA inverters with blown-up power boards or melted IGBT modules?+
Yes. Synchronics specializes in catastrophic IGBT and power-module failures caused by lightning, grid surges, or thermal runaway in Indian solar plants. We perform full power-board reconditioning: damaged IGBT modules are desoldered, replaced, and re-flowed with lead-free solder. PCB cracks are repaired using precision rework equipment. We test repaired boards on SMA-compatible test loads for 8 hours before final assembly and return.
Do you stock SMA spare parts or only offer repair services?+
Synchronics stocks high-demand SMA spare parts including IGBT modules, DC-link capacitor banks, AC/DC contactors, cooling fans, and display modules for Sunny Boy, Sunny Tripower, and Sunny Island series. For emergency breakdowns, we can often expedite parts shipment within 24 hours to major Indian cities. For complete unit repair, we maintain a ready-stock of refurbished SMA inverter units available on exchange-basis to minimize customer downtime.
How do I send my SMA unit for repair?+
Pack the unit securely and courier it to our Vadodara workshop. Include a note with the fault description and your contact details. We will log it into our system and WhatsApp you a job number within 24 hours of receipt. Doorstep pickup is available in Vadodara, Ahmedabad, Surat, Mumbai, and Pune.
What is the cost of repairing a SMA drive or PLC?+
Repair cost depends on the model and the fault. We offer a free diagnosis — once we identify the fault, we provide a fixed quotation before proceeding. Typical repairs cost 20–40% of the new unit price. We will never repair without your approval.
What warranty do you provide on SMA repairs?+
All repaired units carry a 6-month comprehensive warranty covering the same fault and related issues. If the fault recurs within the warranty period, we repair it free of cost.
Do you provide a no-fix, no-fee guarantee?+
Yes. If we cannot repair your SMA unit after diagnosis, you pay only the diagnosis fee (₹500–₹1,500 depending on the product). The unit is returned to you at no additional charge.
