SHENZHEN INVT POWER SUPPLY CO. LTD Equipment We Repair — By Category
SHENZHEN INVT POWER SUPPLY CO. LTD Product Lines We Repair
Our engineers are trained on the full SHENZHEN INVT POWER SUPPLY CO. LTD product range. Below are the major product families we service.
INVT Industrial UPS Systems
High-capacity online and line-interactive UPS units for critical industrial loads. Common issues include battery management system failures, inverter component degradation, and control PCB faults affecting seamless power switching and output stability during grid fluctuations.
INVT Power Factor Correction (PFC) Modules
Thyristor-based and IGBT-based PFC systems for capacitor bank management and harmonic mitigation. Repairs focus on thyristor short circuits, control board failures, and capacitor degradation causing poor power quality and reactive power inefficiency.
INVT Industrial Rectifier Units
Industrial-grade three-phase and single-phase rectifier modules for DC power generation in foundries and metal processing. Common faults include diode bridge failures, transformer winding insulation breakdown, and thermal management system malfunctions.
INVT DC Stabilized Power Supplies
Regulated DC power units for laboratory, medical device manufacturing, and precision assembly lines. Issues range from voltage regulation IC failures, output filter capacitor drying, to reference voltage circuit instability causing load protection triggering.
INVT Modular Power Management Systems
Scalable distributed power architecture with master-slave module synchronization. Repair challenges include inter-module communication bus failures, load sharing imbalance detection, and firmware synchronization issues affecting parallel redundancy.

Common SHENZHEN INVT POWER SUPPLY CO. LTD Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in SHENZHEN INVT POWER SUPPLY CO. LTD equipment arriving at our workshop.
- ✓INVT UPS Battery Management System Failure — Aging lithium or VRLA battery packs combined with failed charger circuits cause under-voltage alarms during utility power loss. INVT systems with 5+ year-old battery strings frequently exhibit degraded cell capacity and charger regulation board component drift.
- ✓INVT Inverter IGBT Module Short Circuit — Thermal cycling stress on solder joints in IGBT bridge modules, combined with inadequate heatsink contact, causes premature gate-drive failure and transistor junction shorts. High ambient Indian summer temperatures (40-45°C) accelerate degradation in poorly ventilated industrial cabinets.
- ✓PFC Thyristor Firing Circuit Malfunction — Contamination-induced gate-cathode leakage in INVT thyristors, or failed optocoupler isolation circuits, prevents proper thyristor conduction angle control. This results in excessive harmonic distortion and reactive power compensation failure in Indian plants with unstable grid voltage.
- ✓INVT Rectifier Diode Bridge Open Circuit — Transformer secondary winding short circuits or utility-side three-phase faults cause diode junction breakdown in INVT rectifiers. Operating in Indian plants with frequent voltage surges and poor earthing exacerbates semiconductor stress.
- ✓INVT DC Output Voltage Regulation Loss — Control loop feedback capacitor aging, reference voltage IC drift, or error amplifier PCB corrosion cause wandering output voltage (overvoltage protection trips or insufficient load voltage). Humidity-prone Indian manufacturing environments accelerate PCB degradation.
- ✓INVT Module Synchronization Bus Timeout Error — Failed RS-485 transceivers, corroded connector pins, or corrupted inter-module firmware communication protocol cause load-sharing imbalance in parallel-redundant INVT systems. Vibration and thermal expansion in Indian automotive assembly lines stress interconnect reliability.

Frequently Asked Questions — SHENZHEN INVT POWER SUPPLY CO. LTD Repairs
Do you repair SHENZHEN INVT power supply equipment anywhere in India?+
Yes, Synchronics repairs the full INVT power supply product range - UPS systems, PFC modules, industrial rectifiers, and DC power supplies. We offer PAN India door pickup from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, and all other major cities. All repairs are completed at our Vadodara, Gujarat facility using INVT-approved components and test procedures.
What is the typical turnaround time for INVT UPS repair at Synchronics?+
Standard INVT UPS repairs (battery replacement, inverter module replacement, control board repair) take 5-7 working days. Complex faults involving firmware issues or multi-module synchronization problems may require 10-14 days. We offer express service (48-hour turnaround) for critical production downtime situations across Indian plants - contact our emergency support line for availability.
Do you stock genuine INVT replacement parts, or can you use equivalent components?+
Synchronics stocks original INVT battery modules, IGBT power modules, capacitors, and control boards in our Vadodara facility. For critical modules, we only use OEM INVT components to preserve warranty and system integrity. For passive components (capacitors, resistors, thermistors), we use industrial-grade equivalents from approved suppliers when OEM stock is unavailable, with written approval from your facility manager.
My INVT UPS shows 'Battery Low' alarm after grid failure - how do you diagnose this?+
Synchronics performs charge-discharge cycle testing on your INVT battery string using dedicated battery analyzers, measures terminal voltage under load, and tests the charger output voltage and current. If battery capacity is below 80% of rated specification, we replace the complete battery module. We also verify charger circuit regulation and BMS firmware to ensure proper charging algorithm execution.
Can Synchronics provide preventive maintenance contracts for our INVT power systems?+
Yes. We offer annual and biannual preventive maintenance packages for INVT UPS and PFC systems. Includes battery capacity testing, filter capacitor ESR measurement, control board function verification, and cooling system inspection. Preventive maintenance extends INVT equipment life by 3-5 years and reduces unplanned downtime risk - particularly valuable for critical pharmaceutical and automotive supply chains in India.
How do I send my SHENZHEN INVT POWER SUPPLY CO. LTD unit for repair?+
