Technical Capabilities

Common Rooftop Solar Failures We Troubleshoot & Fix

Restoring safe electrical flow, preventing arc flash hazards, and returning your plant to peak generation.

Inverter Fault Code Scan

Troubleshooting grid voltage out-of-range trips, DC isolation low resistance faults, MPPT tracking glitches, and internal over-temperature alarms (Sungrow, Growatt, Havells, Luminous, Microtek).

Thermal Hotspots & Cell Cracks

Using FLIR thermal imaging cameras to locate burnt junction box diodes, micro-cracked PV cells, and localized overheating spots that cut string voltage output.

MC4 Crimping & Earthing Pits

Replacing corroded MC4 connectors, repairing weather-damaged DC solar cable insulation, and measuring chemical earthing pit resistance (<5 Ohms).

Warning Signs

5 Signs Your Solar Plant Needs Immediate Repair

1. Sudden 30%+ Drop in Daily Generation

If your inverter output suddenly drops even on bright sunny days, a string fuse may have blown or a bypass diode failed.

2. Red LED Light or Error Code on Inverter

Error codes like "PV Isolation Low" or "Grid Voltage High" prevent your solar plant from feeding power to your home grid.

3. Visible Discoloration or Burnt Marks

Brown burn spots on panel glass or backsheets indicate severe thermal hotspots that require panel replacement or bypass isolation.

4. MCB Tripping During Afternoon Peak

If your AC distribution box MCB trips repeatedly during peak hours, your AC breaker rating or DC cable thickness is undersized.
