At Plexus Energy Limited, years of field experience have taught us a simple truth: most inverter failures are caused by installation gaps and poor maintenance—not faulty equipment.
The good news?
If you remember (and practice) just five basics, your inverter will run more stably and last significantly longer.
1) Heat kills electronics
Inverters need space to breathe. Tight cabinets and poorly ventilated rooms trap heat and shorten component life.
Best practice
- Mount the inverter in a cool, shaded, well-ventilated area
- If it’s too hot to touch, reduce the load immediately and improve airflow
2) Dust blocks airflow
Dust buildup clogs cooling vents, causing internal temperatures to rise quietly over time.
Best practice
- Clean air vents monthly using a soft brush or dry cloth
- Never spray water into inverter vents
3) Loose wiring is a silent danger
Loose terminals create resistance, heat, and eventually burnouts.
Best practice
- Periodically inspect terminals and cables
- Watch for discoloration, melting, or burning smells
- If anything looks off: shut down and re-tighten or re-crimp
4) Startup surge matters more than people think
Motors and compressors don’t start gently. Pumps, fridges, and ACs can draw 2–5× their rated power at startup.
Best practice
- Start heavy loads one at a time
- Avoid switching on multiple high-surge appliances simultaneously
5) Don’t “force run” during alarms
Error codes are protection mechanisms, not inconveniences.
Best practice
- When an alarm appears, take a photo of the error code and wiring
- Share it immediately with your installer or O&M team
- This can make troubleshooting 10× faster
The simple rule that saves inverters
Keep it cool. Keep it clean. Don’t overload it. Share error codes early.

Conclusion
Inverter reliability is rarely about brand failure—it’s about discipline in installation, operation, and maintenance. By applying these five fundamentals consistently, system owners can avoid most breakdowns, extend equipment lifespan, and protect their investment. With the right practices and professional support, inverters are not just power devices—they become long-term, dependable assets.
