Is your solar inverter showing red error lights, grid trip warnings, or zero generation units? Our electrical engineers diagnose loose DC connections, bypassed diode failures, thermal hotspots, and earthing pit degradation.
Restoring safe electrical flow, preventing arc flash hazards, and returning your plant to peak generation.
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).
Using FLIR thermal imaging cameras to locate burnt junction box diodes, micro-cracked PV cells, and localized overheating spots that cut string voltage output.
Replacing corroded MC4 connectors, repairing weather-damaged DC solar cable insulation, and measuring chemical earthing pit resistance (<5 Ohms).
If your inverter output suddenly drops even on bright sunny days, a string fuse may have blown or a bypass diode failed.
Error codes like "PV Isolation Low" or "Grid Voltage High" prevent your solar plant from feeding power to your home grid.
Brown burn spots on panel glass or backsheets indicate severe thermal hotspots that require panel replacement or bypass isolation.
If your AC distribution box MCB trips repeatedly during peak hours, your AC breaker rating or DC cable thickness is undersized.
