Industrial power inverters are practically a boon during power outages. You can depend on them for all your emergency power needs. It doesn’t matter who the inverter manufacturers are or how well you maintain it.
These four factors are a part of wear and tear, which lead to the unit’s eventual failure.
Ultrasonic vibrations lead to mechanical stress on the inverter, which thus ends up in inverter failure. It’s because these vibrations cause friction between the core inductive parts. It adds unnecessary heat to the inverter and further damages its components.
Sometimes you may unknowingly end up using inverters beyond their operating limit. Like most things, using inverters more than its working limit ends up contributing to inverter bridge failure. Ensuring your industrial power inverters are run correctly helps avoid possible failure.
The most common reason for inverter failure is the electro-mechanical wear of capacitors. It’s the capacitors in the inverter that provides a smooth power output even at different current levels.
They, however, have a weak feature.
They have a relatively shorter lifespan, and tend to age faster than dry components. It’s this drying out that leads to inverter failure.
In addition to this, capacitors are very temperature sensitive. It means that high temperatures triggered by the high current will end up reducing its life. It’s because the electrolytes in it tend to evaporate quicker at high temperatures.
Maintaining a lower-than-operating temperature can help prolong its life while replacing capacitors when required can avoid inverter failures.
Overvoltage and current
Extensive current and voltage increase generate heat in the inverter, which can end up damaging the parts. While it’s possible to use fuses or circuit breakers to avoid over-current, it’s not easy avoiding over-voltage. It’s because voltage spikes are not always manmade. Even lighting or solar flares can trigger these dangerous voltage spikes.
Periodical inspection and maintenance of your inverter can help avoid these problems. That’s why most inverter manufacturers like Exeltech offer annual maintenance plans where their professionals periodically maintain your industrial power inverters.
