How to Extend the Lifespan of Your Solar Battery System?

Solar battery saving tips will help you to extend the lifespan of the battery system. In order to maximize output from your battery system, follow these tips:


Controlled overcharging of the battery is known as equalization. It might sound bad, but it can actually be beneficial for your batteries. During normal cycling, some cells in your batteries can become unevenly charged over time. This means that certain cells cannot charge properly, leading to sulfation of the battery plates. Equalization allows all the cells to charge equally, which helps to remove some of the sulfation through a process called gassing. Additionally, gassing helps to mix the electrolyte in your batteries and prevent it from separating into layers. To perform equalization properly, please refer to the instructions provided in your inverter or charge controller manual or reach out to your battery manufacturer for specific equalization guidelines.

Permit Gassing or Boiling:

The battery system needs to gas on a regular basis. Gassing is considered a crucial part of the charging process. Batteries will begin gassing at approximately 14.1 Vdc (12V nominal system), 28.2 Vdc (24V), and 56.4 Vdc (48V). Gassing will result in the formation of hydrogen and water. Therefore, it is important to have a proper ventilation system in your battery bank to avoid hydrogen buildup.

Use Distilled Water in Battery System:

Try to use distilled water in your battery system. It is not advisable to add battery additives or electrolytes, as they start to coagulate on the battery plates and cause more harm than good.

Properly Charge your Battery:

It is essential to charge your battery properly. Battery desulfators can extend your battery life but there is no way to prove that they are actually worth the hype. The decision to use battery desulfators solely depends on you.

Use Large Interconnect Cables:

Large interconnecting cables have a large diameter. This reduces resistance to the flow of electric current and results in even charging. Solar SME suggests a 4/0 size cable for 12V and 24V systems and 2/0 for 48V systems.

Rotate your Battery from Time to Time:

In case you have a large battery bank, it is advisable to rotate batteries within the bank periodically. Batteries in the middle of the bank may not receive a charge equal to the batteries on the outside. Battery rotation will help ensure the balance in the entire battery bank.

Limit Your Number of Batteries:

It is advisable not to use more than 16 batteries in the battery bank. More batteries mean more cable connections. With each connection, there will be an increase in the resistance which results in unequal charging of the battery bank system.

Not Charging Your Battery System:

Never leave your battery system uncharged for a long period of time. Not charging your battery system properly can cause the electrolytes to coagulate on the battery plate. This can impact the battery’s ability to store electric current which eventually reduces its efficiency. Solar SME advises leaving your charging source on, allowing the batteries to charge continuously.
