With industrial power inverters around, you no longer have to worry much about power outages. They provide a continual power supply to minimize downtime and help you maximize productivity. 

However, this is true only if your modular inverters are well maintained and working fine. There are otherwise quite a few problems that may arise and lead to inverter failure. 

Capacitor wear

It is the most common reason for inverter failure because electro-mechanical stress wears out the capacitors. Electrolytic capacitors, unfortunately, have a limited lifespan and tend to wear out quickly. They are also very temperature sensitive. The electrolytes tend to evaporate quicker at high temperatures induced by high current. 


Like any other electrical equipment, the overuse of the inverter either by choice, lack of knowledge, or oversight can lead to inverter failure. Ensuring your industrial power inverters run smoothly at all times helps prevent it. 

Over-current and over-voltage

Over-current and over-voltage can also lead to inverter failure. It happens if the modular inverter’s current or voltage increases more than it’s permitted levels.

It only causes damage to the inverter parts, especially the bridge. While fuses or circuit breakers can help avoid over-current, avoiding over-voltage is not so easy.

It’s because while some voltage spikes are man-made, natural phenomena like lightning, or solar flares, leads to unavoidable voltage spikes.

Ultrasonic vibrations

Ultrasonic vibrations induced by the friction in inductive parts can add to the inverter’s heat production. Extra heat is always not suitable for inverters because it eventually leads to inverter failure.

With so many possible inverter failure options, prevention is always better than cure. Your Exeltech professionals will conduct regular maintenance checks to ensure your industrial power inverters work at optional efficiency for uninterrupted power backup at all times.
