4 Things To Consider Before Buying The Best Battery For Inverter


You decided to upgrade to a new inverter and were excited when it came home. However, after several power cuts, you noticed that the inverter wasn’t performing in an optimum manner. On contacting the technician, you understood the problem. You upgraded your inverter without doing the same with your inverter battery and assumed that the existing battery would work just fine. Unfortunately, this is not the case. For an inverter to work efficiently, it requires a compatible battery. Having realised your mistake, there are a few key aspects you should consider and understand before buying the best battery for inverter. It is important to note that buying an inverter battery is a methodical process and not something that you can purchase correctly in an impromptu manner.

1. Inverter and Battery Compatibility

This is the first thing that you should do when deciding to buy the best battery for inverter. If your battery is not compatible with the inverter, several consequences can take place. Your inverter may not work at all, making it an impractical box that takes up space. Secondly, your inverter may not perform efficiently, thus affecting the running of the appliances. Thirdly, it may damage the inverter, your appliances, or even both. Thus, you must check the compatibility before purchasing a battery. For example, if your inverter has a voltage of 24V, purchase a battery with the same voltage. A tip that you can use to ensure compatibility is to purchase the inverter and the battery in the form of a combo.

2. Your Home/Office Power Requirement

Gauging the power or load requirement is an important part in the process of purchasing the best battery for inverter. Load requirement is the total amount of power that your appliances will use up while running on an inverter. The process is the same whether you are purchasing the battery for home or office use. The power requirement depends on the number of appliances you want to run. It could be as simple as running fans and lights or complicated as running fans, lights, TVs, and other high-powered appliances. The total load is measured in Watts and this requirement plays an important role in selecting the battery capacity.

3. Determining Backup Duration and Battery Capacity

Once your load requirement is confirmed, the next step is to calculate your backup duration in hours. You need to do this correctly or you may end up purchasing an inverter battery with less capacity. The backup hours depends upon the average duration of power cuts in your area.

Once the duration is confirmed, you can decide what battery capacity to opt for. This can be done with the help of a simple formula, wherein you multiply the load requirement with the backup duration, and divide the result with the voltage of the battery.

Battery capacity = (load requirement * backup-time * aging factor) / (battery voltage*battery efficiency*inverter efficiency)

The following values are constant

  • Inverter aging factor = 1.25
  • Battery efficiency = 0.8
  • Inverter efficiency = 0.8
  • Battery voltage  = 12V (in most cases)

4. Which Type of Battery to Choose?

Another critical aspect that you must consider is the type of battery. You can choose from three types of batteries – flat plate, gel, and tubular batteries.

Each of these types of batteries have different features, costing, efficiency levels, advantages, disadvantages, and environmental friendliness. Hence, understand your requirements and set a budget, and then select the type of battery suitable for your needs.
