1.Although inverters are highly reliable, on-site maintenance and inspections remain critical for long-term stability. Key daily checks include:
Ensure auxiliary equipment (e.g., motors) operates normally;
Monitor inverter temperature and ventilation to maintain optimal cooling;
Check for abnormal noises, odors, cabinet overheating, or vibrations;
Verify input/output voltage and current remain within normal ranges;
Avoid steam or gas sources near cabinets to prevent damage;
Tighten main circuit cable connections after one month of installation, then every six months, and clean dust with a vacuum;
For unused inverters, power them for ≥1 hour every six months to prevent component moisture damage and capacitor degradation.
2.Maintenance precautions:
Operate in anti-static, low-interference environments with controlled humidity, temperature, and dust; seal cable entries and avoid prolonged door openings;
Discharge capacitor residual voltage before inspections;
Never measure output insulation with a megohmmeter to avoid component damage.
