8 untold benefits of the Mercury inverter

Mercury Inverter is an electronic device used for converting AC current into DC current. It is used in solar photovoltaic system, water pumping systems and other small scale applications where variable torque or variable speed operation is needed.


In this post, I will explores some of the top benefits of using a mercury inverter in your next project.

8 Benefits of Mercury Inverter


  • The cost of ownership is significantly low

The cost of ownership of a mercury inverter is significantly low when compared to other types of inverters. This is because mercury wetted transformers are very durable. They are extremely resistant to humidity and other environmental factors that may cause other types of inverters to fail. This makes them a worthwhile investment for overall longevity. In addition, mercury wetted transformers have a high power factor. This allows them to respond very quickly to changes in demand, which results in a reduced amount of energy being drawn from the grid. This ultimately help to save significant amounts of money on  electricity bill.

  • It has a fast response time

Another benefit of the mercury inverter is its fast response time. This is particularly important for solar inverters, where the inverter is responsible for converting the direct current from the solar panels into alternating current that can be used in a home or business. One of the main advantages of solar energy is that it produces DC power that is relatively consistent throughout the day. During certain times of the year, solar panels produce more power than others. This is because the sun’s light intensity varies throughout the year and the seasons. The mercury inverter is quick to adjust to these changes in solar panel output, and uses an efficient transformer to adjust the power produced.

  • Emergency shutdown capacity

The mercury inverter’s ability to respond quickly to changes in demand also makes it suitable for emergency shutdowns. For example, if a piece of equipment experiences an internal fault or a fire, an emergency shutdown function will close the circuit to prevent further damage. The inverter is designed to trigger this emergency shutdown function in the event of an emergency. This feature likely has its origins in the days of using mercury-arc rectifiers. In the event of a fault in the system or low input voltage, a switch will close and direct the current to the arc between the electrodes. This arc is extinguished by the current flowing through the mercury flow. The shutdown is complete when the arc flow stops completely.


  • Lightweight and compact design

The mercury inverter is also lightweight and compact, which makes installation noticeably easier. This makes the mercury inverter a great option for projects of any size, especially in remote locations. The mercury inverter is also highly efficient. It boasts an efficiency rate of 90%, which is much higher than the typical inverter efficiency rate of around 80%.

  • Continuous rotation operation

In certain applications, such as pumping water, it may be necessary to stop the pump in order to change the direction of the water flow. The mercury inverter, however, can operate the pump continuously. This is because the mercury inverter can switch direction without shutting the pump down. This means that the pump can be used to distribute water in a continuous rotation.

  • Auto restart function

Another feature of the mercury inverter is its automatic restart function. This function automatically restarts the equipment in the event of a power outage.The equipment also has the ability to self-recover after power surges, protecting the internal components from damage. The automatic restart function is a particularly useful feature for solar installations. This is because many areas experience periodic power outages due to changes in the weather and other factors. An automatic restart function is useful for ensuring that a solar installation stays online even in the event of a power outage.

  • Environmentally friendly

The mercury inverter is environmentally friendly because it does not require cooling like other types of inverters such as the shaded-pole or string inverter. It does not require cooling because it uses a mercury-wetted transformer. The mercury-wetted transformer is essentially a transformer with a tube of liquid mercury inside it. This type of transformer is particularly useful in areas that have very high temperatures, as it is able to operate efficiently at high temperatures. This is an important feature, as many areas that are not connected to the grid operate on solar energy. In these areas, the temperature can reach very high levels. The mercury-wetted transformer, however, is able to operate efficiently at high temperatures.

  • Supports fast Battery Charging

Finally, the Mercury Inverter supports fast battery charging. This is because a mercury wetted transformer produces a higher voltage than many other types of transformers. This higher voltage is particularly useful when charging batteries with solar energy. This is because batteries charge more quickly at a higher voltage. The higher voltage provided by the mercury wetted transformer, results in a quick charge. This quick charge, in turn, allows the battery to be used for a longer period of time. This is particularly useful in remote locations, where solar energy is often the only source of electricity.


Throughout this post, I have extensively explained the benefits of using a mercury inverter. It is an efficient, lightweight device that is particularly useful in solar installations, as it can respond quickly to changes in solar panel output. In addition, the mercury inverter can operate continuously, can be used to charge batteries quickly, and is environmentally friendly.
