It does not matter if you plan to buy new industrial power inverters or if you are looking to upgrade your old one. It is very important that you select the right inverter for your industrial needs.
There is no point in buying any random inverter. Nor is it wise to buy inverters just because some other industry is using.
You need to buy the right inverters based on your industrial power needs.
And to do this, you will first have to do your homework and understand the basics.
1. Know your power requirements
The most important factor that goes into buying an industrial power inverter is your power requirement. It is the amount of power you will require to power your electrical machines and appliances during a power failure.
You need to add the total power all these machines, equipment, and appliances will consume at a given time. Once you know this, you have to buy industrial power inverters with a slightly higher wattage than the total. This is to compensate for the few seconds’ starting surge of power the appliances will be consuming when they start.
2. Calculate the inverter’s VA rating
The VA rating stands for volt-ampere rating and is supplied by the inverter to the equipment. It means that if the inverter operates with 100% efficiency, then the power requirement of the electrical items equals the power supplied by the inverter.
However, this is not reality.
There is nothing like 100% or ideal efficiency range.
Most inverters have an efficiency range (the inverter’s power factor) from 60% to 80%. It is nothing but the ratio of power required by the appliance to the power supplied by an inverter.
On average, the power factor of most inverters lies between 0.6 to 0.8. you need to choose an inverter with a VA rating that equals or is a bit more than your requirements.
3. Find out which battery the inverter needs
When you buy inverters, remember that it is incomplete without the right battery. The battery is its backbone which has a major impact on the inverter’s performance and life.
It gives you the answer to a few other questions you may have while selecting your inverter. For example, it decides how much backup the inverter provides and how many hours it will run all your equipment. This denotes the battery capacity, which is expressed in Ah or Ampere hours.
You will find that there are batteries of varying capacities in the market. So making a choice isn’t so easy. You have to decide on the right ones for your inverters. And this is once again done through a little calculation, more specifically, a reverse calculation.
For example, think that you are looking for battery backup for three hours.
In this case, you can calculate the battery capacity by multiplying your total power requirements by the number of backup hours. Then divide this total by the battery voltage, which gives you the ideal battery capacity for your inverter battery.
Making this simple calculation can save lots of inconveniences while selecting the right inverters. The battery capacity is an important factor to consider because the inverter lasts for as long as the battery capacity. A higher capacity battery will last longer than a lower capacity one.
The above-mentioned three tips will go a long way in helping you select the right inverters to keep your machinery running even during a power outage. Don’t worry if you can’t make the calculations. Your Exeltech professionals will help you with the selection.
