Generac Industrial Evolution Series Standby Generators
Heavy-duty stationary units with 15-2000kW output for critical loads. Repair focus areas include fuel injection controller failures, alternator voltage regulation faults, crankshaft position sensor errors, and automatic transfer switch (ATS) logic board malfunctions.
Generac PowerPact Modular Systems
Scalable multi-module generator configurations for large industrial operations and data centres. Common electronic failures: module synchronization controllers, load-sharing PCBs, harmonic mitigation circuits, and communication interface card degradation.
Generac Mobile Products GenPower Engine Control Units
Engine-mounted controllers for variable speed and load-following applications in construction, mining, and temporary power supply operations. Typical faults: throttle servo motor failures, fuel solenoid drivers, exhaust temperature sensor errors, and ECU firmware corruption.
Generac Automatic Transfer Switches (ATS) & Control Panels
Static and electromechanical switching systems integrating microprocessor logic for seamless grid-to-generator transition. Faults include voltage sensing relay failures, microprocessor reset loops, contactor drive circuit burnout, and communication protocol corruption in networked installations.
Generac Engine Fuel Injection & Emissions Control Systems
Integrated fuel delivery and emissions management electronics for compliance with Indian CPCB regulations and Euro IV/V standards. Common failures: fuel injection controller signal loss, oxygen sensor interface circuits, diesel particulate filter regeneration logic faults, and emissions sensor failures.

Common GENERAC Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in GENERAC equipment arriving at our workshop.
- ✓Generac AVR voltage regulation module failure — Excitation winding open circuits, rectifier diode burnout, or capacitor dry-out in the automatic voltage regulator cause erratic output voltage ranging 180V-280V AC in 230V applications. Compounded by thermal stress in Indian ambient temperatures exceeding 45 degrees Celsius.
- ✓Engine cranking controller lockout and no-start condition — Generac PowerCommand microprocessor faults, low-voltage battery sensing circuit errors, or fuel solenoid driver IC shorts prevent engine start sequence initiation. Thermal cycling and moisture ingress into control modules accelerate failure in monsoon-prone Indian regions.
- ✓Load-sharing synchronization error across parallel Generac modules — Synchronization PCB communication loss, CAN bus termination resistor faults, or incompatible firmware versions across multi-unit installations cause unequal kW and kVAR distribution, overloading one module while underloading others.
- ✓Automatic Transfer Switch failure to transition during utility blackout — Generac ATS microprocessor logic faults, voltage sensing circuit dropout, contactor coil open-circuit, or timing relay degradation prevent proper grid-to-generator switching. Inadequate neutral bonding during switchover causes nuisance trips in Indian grid conditions with high harmonic distortion.
- ✓Fuel injection controller fault codes P0016, P0017, P0261-P0298 — Generac fuel injection ECU detects misaligned injector timing, shorted fuel solenoid drivers, or sensor signal faults (crank/cam position, fuel pressure, rail temperature). Diesel contamination and water ingress trigger multiple simultaneous codes in long-stored units.
- ✓Generac iC Series inverter module failure and no AC output — MOSFET or IGBT die shorts in the inverter bridge, gate drive transformer saturation, or snubber capacitor failure cause zero or severely distorted AC waveform output despite normal DC bus voltage. Paralleling two failed units creates cascading damage risk.

Frequently Asked Questions — GENERAC Repairs
Do you repair Generac equipment anywhere in India?+
Yes. Synchronics repairs the full Generac product range - portable generators, standby power systems, engine control modules, ATS panels, and fuel injection controllers. We offer PAN India door pickup from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Bangalore, and all tier-1 and tier-2 industrial cities. Your equipment is transported to our 10,000+ sqft facility in Vadodara, Gujarat, diagnosed, repaired, and returned within 5-10 business days.
What is the typical repair turnaround time for a Generac PowerCommand fuel controller?+
Most Generac fuel injection and engine control module repairs are completed within 48-72 hours. This includes diagnostic testing, component replacement (injectors, solenoids, sensors), ECU reprogramming with OEM calibration data, and validation testing under simulated load conditions. Customers can track repair progress and receive real-time notifications through our web portal.
Can Synchronics repair Generac automatic transfer switches (ATS) that fail to transfer between utility and generator?+
Absolutely. ATS failure is one of our most common Generac repairs. We diagnose voltage sensing circuit faults, test microprocessor logic, replace failed contactors, verify neutral bonding, reprogram transfer timing parameters specific to Indian 3-phase 50Hz grids with high harmonic distortion, and perform live switchover validation. We ensure your critical loads never lose power during grid failure.
Do you stock Generac spare parts - AVRs, solenoids, fuel injectors, and microprocessors?+
Yes. Synchronics maintains critical Generac spare parts inventory including Automatic Voltage Regulators (AVR modules), fuel solenoids, diesel injectors, crankshaft and camshaft sensors, and microprocessor components. For obsolete or slow-moving parts, we procure directly from authorized Generac distributors in India within 5-7 business days at competitive pricing, keeping your repair costs transparent.
What is Synchronics' warranty on repaired Generac power systems and control electronics?+
All Generac repairs carry a 12-month parts and labour warranty. If any component fails within 12 months due to manufacturing defects or workmanship errors, we repair or replace it at no charge. For critical infrastructure (hospitals, data centres, telecom), we offer extended 24-month warranty and on-call emergency repair support with 4-hour response commitment across major Indian metros.
How do I send my GENERAC 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 GENERAC 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 GENERAC 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 GENERAC 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.
