SUNPOWER Equipment We Repair — By Category
SUNPOWER Product Lines We Repair
Our engineers are trained on the full SUNPOWER product range. Below are the major product families we service.
SunPower Inverters (Grid-Tie & Hybrid)
High-efficiency grid-connected and hybrid inverters for commercial solar installations and industrial microgrids. Common faults include capacitor degradation, IGBT switching failures, firmware corruption, and AC/DC bus voltage regulation loss.
SunPower MPPT Charge Controllers
Maximum Power Point Tracking controllers for off-grid and hybrid renewable systems. Repair challenges include input voltage regulation failure, battery over-charge protection faults, thermal sensor malfunctions, and LCD/communication port failures.
SunPower Power Management Modules (PMM)
DC-DC converters and power distribution modules for industrial automation and renewable energy systems. Typical failures: step-down converter instability, isolated gate driver faults, bulk capacitor dry-out, and protection relay malfunction.
SunPower System Control Units (SCU)
Microprocessor-based controllers managing multi-source power systems (solar, grid, battery, backup gen). Common issues: firmware crashes, CAN/RS485 communication timeouts, analog input calibration drift, and relay output sticking.
SunPower Isolated DC-DC Converters
Galvanically isolated converters for industrial backup power and microgrid applications. Repair needs: transformer winding shorts, output voltage feedback loop instability, overvoltage crowbar failure, and thermal management issues.

Common SUNPOWER Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in SUNPOWER equipment arriving at our workshop.
- ✓Inverter refuses to sync with grid voltage — SunPower grid-tie inverters require precise phase-locking to utility voltage. Failure is usually caused by AC voltage sensing circuit degradation, phase-locked loop (PLL) firmware corruption, or transformer saturation on the AC output side.
- ✓MPPT charge controller shows 'INPUT VOLTAGE HIGH' error and shuts down — SunPower MPPT units ground-reference input voltage against battery nominal. This fault occurs when PV array open-circuit voltage (Voc) exceeds firmware limits (typically 150V), or input voltage sensing divider network has drifted due to resistor aging or moisture ingress.
- ✓Battery over-charge protection not activating despite rising cell voltage — SunPower charge controllers use thermistor-based temperature compensation and voltage comparators to prevent over-charge. Failure indicates thermistor open-circuit, comparator IC failure, or firmware logic error in the charge algorithm.
- ✓Inverter output shows DC offset on AC waveform causing breaker nuisance trips — SunPower inverters use PWM gate drive and LC output filters to generate clean AC sine wave. DC offset appears when output filter capacitor develops series resistance (ESR) rise, or the PWM dead-time compensation algorithm drifts due to MOSFET parameter aging.
- ✓CAN bus communication timeouts between SCU and distributed modules — SunPower System Control Units communicate with peripheral charge controllers and inverters over CAN (Controller Area Network). Timeouts arise from CAN transceiver IC shorts, bias resistor network degradation, or firmware not re-transmitting on collision detection.
- ✓Isolated DC-DC converter outputs zero volts despite primary power applied — SunPower isolated converters rely on high-frequency transformer and resonant switching. Complete output loss indicates transformer primary-to-secondary short, oscillator IC failure, or output diode forward-bias loss.

Frequently Asked Questions — SUNPOWER Repairs
Do you repair SunPower equipment anywhere in India?+
Yes. Synchronics repairs the full SunPower product range - inverters, MPPT charge controllers, power management modules, system control units, and isolated converters. We offer PAN-India door pickup from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Bangalore, and all metro cities. All repairs are handled at our main facility in Vadodara, Gujarat, with 48-72 hour turnaround for most modules.
Can you repair SunPower inverters that have firmware corruption or won't boot?+
Absolutely. SunPower inverters occasionally experience firmware crashes due to power surges or incomplete updates. Synchronics has in-house JTAG and bootloader programming equipment to recover corrupted firmware, validate bootloader checksums, and restore factory settings using original SunPower firmware archives. We test full inverter operation before shipping.
What happens if my SunPower MPPT controller no longer charges the battery?+
Battery charging loss is usually caused by input diode failure, PWM buck converter MOSFET degradation, or battery voltage sense circuit malfunction. Synchronics performs load-line testing to isolate the fault, replaces power semiconductors with rated equivalents, recalibrates battery chemistry (LiFePO4, Lead-Acid, etc.) via firmware, and validates charging current ramps correctly from 0-100A.
Do you stock spare parts for SunPower repairs or order from OEM?+
Synchronics maintains inventory of common SunPower replacement components: capacitors, MOSFETs, gate drivers, CAN transceivers, thermal fuses, and LCD modules. For rare or obsolete parts, we source from authorized SunPower distributors or use qualified industrial-grade cross-reference components with equivalent electrical ratings and thermal specifications.
Can Synchronics repair SunPower equipment still under manufacturer warranty?+
Yes. Synchronics is an authorized third-party service center and does not void SunPower warranty (in most cases). We document all repairs with detailed technical logs, photograph damage before work, and provide comprehensive repair certificates. Customers can contact SunPower service line with our repair report if warranty clarification is needed.
How do I send my SUNPOWER 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.
What is the cost of repairing a SUNPOWER 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 SUNPOWER 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 SUNPOWER 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.
