What you wanna consider the most part when you’re dealing with a battery back replication or UPS is first off, everybody goes with the kilowatts that they wanna run with. Well, what you wanna do is you wanna know where the battery is gonna be, the temperature its gonna be at, what is the design criteria of the battery.
Do you want a one year free replacement? Do you want a 10 year design life battery? Do you want a five-year design life pattern, or do you want a 20 year or in cases they may want a 25 year design life, which would be a nickel type of battery. So all those criterias you wanna kind of look at, you wanna look at, so your backup time, and then what is taken into consideration with the backup time is temperatures.
You wanna know what the battery is going to run at? Cause if the battery is running at an RTU on the side of a well shack, it’s gonna be running in minus 30, minus 40. Well, you need a battery that’s actually gonna perform.
A lot of these inexpensive batteries, these one-year free replacements don’t perform past minus 25. So you wanna know your battery size. You wanna figure out your battery size and then you figure out your actual charging source and your ups size.
To be sure you wanna know, do you have AC loads? Do you have DC loads? What kind of AC loads are they gonna be? Do you need a pure sine wave inverter? Do you need a modified sine wave inverter? What will work the best and then go from there and size the battery accordingly.
So that’s typically what we would try to do when we wanna size a battery or a UPS application or a backup application.
