SOLA Equipment We Repair — By Category
SOLA Product Lines We Repair
Our engineers are trained on the full SOLA product range. Below are the major product families we service.
SOLA/SOLARC UPS Systems
Single-phase and three-phase uninterruptible power supplies designed for industrial and commercial loads. Common failures include battery charger faults, inverter module degradation, and transfer switch latching issues that disrupt critical power continuity.
CVT Constant Voltage Transformers
Ferroresonant voltage regulation devices that maintain stable output under variable input conditions. Frequent issues include saturation core burnout, secondary winding insulation breakdown, and mechanical vibration causing internal resonance failures.
Static Voltage Regulators
Thyristor-based AC voltage regulation modules for precision industrial loads sensitive to voltage fluctuation. Typical faults include thyristor short-circuit failures, gate drive circuit breakdown, and sensing transformer malfunctions.
Battery Backup Modules
Dedicated battery charger and DC-AC inverter modules used in SOLA UPS architectures. Common repair items include failed IGBT modules, capacitor bank degradation, and sensing circuit faults that prevent proper charging or backup operation.
Transfer Switches and Bypass Units
Static and mechanical transfer switches that seamlessly switch between mains and backup power. Failure modes include relay contact erosion, logic board malfunction, and synchronization circuit drift causing unsafe power transitions.

Common SOLA Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in SOLA equipment arriving at our workshop.
- ✓UPS Inverter Output Voltage Collapse — SOLA UPS inverter stage failures typically stem from IGBT module short-circuits, gate driver IC burnout, or output filter capacitor bank degradation. Repeated mains voltage surges and poor input protection accelerate inverter module wear in Indian industrial environments with unstable power supply.
- ✓CVT Ferroresonant Core Saturation — SOLA CVT transformers can experience core saturation and burnout when exposed to prolonged input overvoltage (above rated 130% nominal), insufficient cooling, or internal winding insulation failure. Indian plants operating from unstable three-phase supplies often encounter this fault when incoming voltage exceeds CVT design limits.
- ✓Battery Charger Voltage Regulation Drift — SOLA BCM (Battery Charger Module) regulation failures occur due to zener diode leakage in the sense circuit, transformer tap selector relay contact wear, or op-amp IC drift in the feedback control loop. Tropical humidity and thermal stress in Indian data centres accelerate this degradation.
- ✓Transfer Switch Synchronization Failure — Static Transfer Switches (STS) in SOLA UPS systems can fail to synchronize with mains voltage due to phase-locked loop (PLL) IC malfunction, comparator circuit drift, or zero-crossing detection sensor failure. This causes unsafe or delayed power transfers during mains loss events, leaving loads unprotected.
- ✓UPS Audible Alarm Malfunction and False Warnings — SOLA UPS alarm circuits fail when piezoelectric buzzer elements crack, alarm enable relay contacts oxidize, or microcontroller firmware misinterprets sensor signals under noisy electrical environments. Indian manufacturing plants with high RF interference often report spurious alarms masking real fault conditions.
- ✓Rectifier Bridge Diode Failure in Power Supply — SOLA power supply rectifier bridges (typically three-phase bridge configurations) fail when exposed to input phase imbalance, transient overvoltage spikes, or extended operation at rated current in poorly ventilated cabinet enclosures. Indian grid conditions with phase imbalance aggravate diode reverse recovery stress.

Frequently Asked Questions — SOLA Repairs
Do you repair SOLA equipment anywhere in India?+
Yes. Synchronics repairs the full SOLA product range — UPS systems, constant voltage transformers, static voltage regulators, battery modules, and transfer switches across all generations. We offer PAN India door pickup service from Mumbai, Delhi, Bangalore, Pune, Chennai, Hyderabad, Ahmedabad, Kolkata, and all other major cities. All repairs are performed in our ISO-certified facility in Vadodara, Gujarat, with same-day diagnostics and 7-10 day average turnaround.
What is the typical repair cost and warranty for SOLA UPS systems at Synchronics?+
Repair costs vary based on fault severity — minor capacitor or relay replacement typically costs Rs. 8,000-15,000, while major inverter module replacement ranges Rs. 35,000-60,000 depending on UPS capacity. All repairs include 12 months warranty covering the repaired component plus 30 days extended testing. We provide transparent quotations before work begins and source OEM-equivalent parts to restore equipment to factory specifications.
Can you repair SOLA CVT transformers with burnt secondary windings?+
Yes. Synchronics specializes in SOLA CVT rewind work using original winding gauge and high-temperature insulation materials. We test rebuilt transformers using variac ramp and thermal imaging to verify saturation recovery and safe operating margin. Full CVT rewind typically takes 10-14 days and costs Rs. 20,000-40,000 depending on kVA rating. We guarantee rewind quality and provide performance certificates matching original SOLA test standards.
How do I know if my SOLA UPS has a failed inverter module?+
Common warning signs include: (1) UPS fails to supply backup power during mains loss despite battery charge indicator showing full, (2) inverter output voltage is unstable or completely absent, (3) UPS emits high-pitched oscillation sound during battery mode, (4) transfer switch indicator shows incomplete power transfer. Contact Synchronics for immediate diagnostic testing. We can confirm inverter module failure using oscilloscope analysis and component test benches, then provide repair costs before proceeding.
Does SOLA equipment require preventive maintenance service in India's climate?+
Absolutely. Indian tropical climate and industrial dust accelerate SOLA equipment degradation — we recommend annual preventive maintenance for data centre UPS systems and bi-annual service for manufacturing plant CVTs. Maintenance includes: capacitor ESR testing, diode forward voltage verification, cooling fan inspection, battery terminal corrosion removal, and dust filter cleaning. Preventive maintenance typically costs Rs. 5,000-12,000 annually and prevents costly emergency repairs that disrupt critical operations.
How do I send my SOLA 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 SOLA 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 SOLA 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 SOLA 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.
