FIMER Product Lines We Repair
Our engineers are trained on the full FIMER product range. Below are the major product families we service.
FIMER AURORA String Inverters
Single-phase and three-phase string inverters for residential and commercial rooftop solar installations. Common issues include MPPT tracking failures, grid synchronization errors, and DC-side capacitor degradation affecting power output stability.
FIMER CENTRAL INVERTERS (Utility Scale)
High-capacity central inverters for utility-scale solar farms and grid-connected PV plants. Repair focus includes phase imbalance correction, cooling system failures, IGBT module degradation, and communication board malfunctions.
FIMER HYBRID & STORAGE INVERTERS
Integrated solutions combining solar inverter and battery management for energy storage applications. Common failures involve BMS (Battery Management System) communication loss, bidirectional converter faults, and DC-link capacitor aging in charge-discharge cycles.
FIMER PVI-LIGHT SERIES
Compact three-phase inverters for commercial and light-industrial solar applications in India. Typical repair issues include transformer overheating, filtering stage failures, and relay contact oxidation causing grid relay trips.
FIMER COMM CONTROL BOARDS
Communication and control modules managing DSP firmware, grid monitoring, and remote shutdown functions. Repairs address corrosion in industrial humid environments, software crashes, and RF interference sensitivity in crowded substations.

Couriered repairs accepted from any city in India. Doorstep pickup available in Vadodara, Mumbai, Pune, Ahmedabad, Surat, Chennai, and more.
Common FIMER Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in FIMER equipment arriving at our workshop.
- ✓MPPT Tracking Loss - Inverter not harvesting maximum power — FIMER string inverters experiencing MPPT algorithm corruption or ADC sampling failure due to thermal drift in ambient temperatures above 45C common in Indian summers. Typically caused by firmware instability or DSP memory bit-flip under high heat stress.
- ✓AC Output Frequency Out of Range (47.5-52 Hz errors) — Grid synchronization phase-lock-loop (PLL) instability in FIMER inverters, especially during weak grid conditions common in rural Indian installations. Caused by incorrect Radian/second conversion coefficients or Phase-Frequency Detector (PFD) charge pump leakage.
- ✓DC-Link Capacitor Failure - Visible bulging, ESR increase — Electrolytic ripple capacitors in FIMER inverter DC bus aging prematurely due to high ambient temperature cycling, industrial dust ingestion into cooling vents, and voltage stress during grid frequency transients. Typical lifespan reduction in Indian climate is 30-40% versus Europe.
- ✓Grid Relay Not Closing - Inverter cannot synchronize to AC grid — FIMER AC isolation relay coil burnout or contact oxidation from humidity and salt-spray environments near coastal Indian industrial zones. Microcontroller GPIO pin failure preventing relay drive signal generation also common in EMI-rich environments.
- ✓Firmware Crash or Bootloader Failure - Inverter goes to black screen — FIMER DSP memory corruption from power surge, lightning strike via DC cables, or corrupted firmware upload due to USB connection dropouts. Flash memory bit-flip induced by cosmic radiation or repeated power cycles under low voltage conditions (brown-out).
- ✓Hybrid Inverter Battery BMS Communication Loss (Charge stops) — RS485 communication cable shielding failure between FIMER hybrid inverter and battery module BMS in vibration-prone manufacturing environments. Ground loop issues causing common-mode voltage violations, or BMS firmware timeout due to slow CAN message response time.

Frequently Asked Questions — FIMER Repairs
Do you repair FIMER equipment anywhere in India?+
Yes. Synchronics repairs the complete FIMER portfolio - string inverters, central inverters, hybrid inverters, battery management systems, and control boards. We offer PAN India pickup and delivery via our courier network from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Bangalore, Kolkata, and all tier-2 cities. All repairs are completed at our main facility in Vadodara, Gujarat.
What is the typical turnaround time for FIMER inverter repair?+
For standard FIMER string inverter repairs (capacitor replacement, firmware reload, relay repair), turnaround is 5-7 working days from receipt at Vadodara facility. Central inverter and hybrid system repairs requiring component sourcing or DSP programming typically take 10-14 days. We prioritize solar season emergency repairs with 48-hour expedited service available for industrial clients in Gujarat and nearby states.
Which FIMER inverter models does Synchronics repair most frequently?+
Aurora string inverter series (Aurora 5.0-6.0 kW) are our highest-volume repairs due to widespread adoption in Indian rooftop solar projects. We also see high repair volumes for FIMER PVI-Light 10kW and Prima Central inverters from large solar farms and manufacturing plants. Hybrid inverter repairs are growing rapidly as Indian industrial clients adopt energy storage. We maintain parts inventory for all major FIMER models.
Do you provide warranty on FIMER repairs and can you issue certificates of compliance?+
All FIMER repairs carry 12-month parts and labour warranty. Synchronics issues detailed test reports and performance certificates (no certification) documenting power curve compliance, efficiency, and grid code validation per IS/IEC 61727 standards. We provide signed repair documentation suitable for insurance claims and customer billing. Hybrid inverter repairs include BMS calibration certificates.
What documentation do I need to send with my FIMER inverter for diagnosis?+
Please provide: original fault description, installation date, warranty card, last service record (if any), and site ambient temperature range. For hybrid inverters, include battery specification sheet and BMS configuration file if available. Photos of error codes or LED blink patterns are helpful. Synchronics will perform free diagnostic testing and email a repair quotation with detailed findings within 24 hours of receipt.
How do I send my FIMER 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 FIMER 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 FIMER 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 FIMER 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.
