DABAJA SERVICE
Inverter Repair & Diagnostics
Engineering-first inverter diagnosis for error codes, charging faults, no-output faults, cooling problems, power-stage failures, MPPT issues, and control-power problems.
How DABAJA approaches it
The goal is to identify the failed function before replacing parts. DABAJA approaches inverter repair by blocks: input, auxiliary power, drivers, power stage, sensing, control, charging/MPPT, DC bus, cooling, and output.
WHAT WE CHECK
- Visual inspection and evidence of overheating or damage
- Short-circuit and power-device checks
- Auxiliary power-rail measurements
- Gate-driver and switching-stage checks where appropriate
- DC-bus and battery-side measurements
- Cooling and fan operation
- Charging, MPPT, sensing and communication behavior
- Controlled final testing after repair
IMPORTANT
Safety & Scope
Recommendations depend on the actual equipment, measurements, installation condition, and operating limits. High-voltage inverter, PV, battery, and distribution-board work can be hazardous; this website is not a substitute for safe isolation, proper instruments, or qualified on-site work.
