Sizing Your Battery Bank
2021-03-10

We discuss batteries as an energy storage device; however, batteries likewise need to offer sufficient power for your applications. When you are sizing your battery bank, taking an inventory of whatever, you require your batteries to power, and identifying your overall energy requirements are the very first things to do.

Current Requirement 

Every electronic gadget will show the electrical load it draws, on its packaging or on its label. This load will be mentioned either in watts or amps.

If it offers amps in hours, then estimate how long this gadget will be utilized each day and then multiply it by the current in amps. So, now you have the amp-hour requirements. If it shows watts, just divide by the voltage to obtain the current in amps. Once again, estimate in hours for how long it will be on each day and then multiply it by the current in amps. Now you have amp-hours for every device. Sum them all up and you will have your daily energy load. This will identify how much battery capacity you require.

The 2nd step is to find the maximum power requirement. This can be done either in watts or amps. Since you have already found the amps in the 1st step, you already have all the data that you need. Find the maximum current required by summing up all the potential current draws that might take place at the same time. Now you understand the current requirements of your battery. Despite what battery you purchase, you need to be able to charge them. If your charging source of power (for instance, battery charger, solar panels, and so on) cannot fulfill your everyday needs, you need to decrease your loads or enhance your charging power. Otherwise, your battery bank will not get fully-charged and you will decrease the available capacity for the subsequent discharge.

Capacity Requirement 

Let‘s state you created an everyday usage of 500Ah.

Taking a look at Melasta‘s 12V batteries, you have choices from 5 to 300Ah. If you select the 12V, 100Ah battery, you will need 5 batteries. If you choose the 12V, 300Ah battery, you will need 2. After comparing the 2 batteries and finding out the cost difference between these alternatives, you may choose to purchase 2 batteries despite the fact that their overall capacity will be higher than your requirements. Your battery does not have excess capacity unless your charging power supply does its job. You are paying for capacity you will never ever utilize if your recharge power supply is adequate to completely charge your battery bank in the designated time.

This is less of an interest in lithium batteries than with lead-acid batteries, given that lithium batteries are not negatively impacted by remaining in a partial state of charge. An insufficient charging cycle does not offer you the most precise details about how much capacity you have actually left in your battery. Understanding you have 500Ah in a 500Ah battery bank is a different thing than approximating you have about 500Ah in a 600Ah bank. Lithium batteries‘ high effectiveness, usable capacity, and capability to not be impacted by a partial state of charge make it simple to size your battery bank. When you understand what you require, Melasta‘s batteries in 12, 24, and 48 volts and a wide variety of amp-hours make it simple to discover the best solution for you.
