How to Maintain Your Solar Battery

How to Maintain Your Solar Battery

  09 May 2019

Solar energy batteries are generally a very important part of the entire solar energy system. The power that is trapped and stored from the solar panels is ultimately transferred and stored in the solar battery. The battery is responsible for discharging over time when power is not being generated by the solar energy system. Maintaining your solar battery is not as easy as it looks. There are many things that you need to keep in mind when it comes to maintaining a battery. The most important factor that determines your maintenance strategy is the kind of battery you have. Some people have a lead acid battery, while others prefer one with a lithium chemistry.  Here are a few tips for maintaining your solar battery.

Check the Voltage Periodically

One of the most important things that you need to do is check the voltage of the battery periodically. If you have multiple batteries installed in a series, you should make use of a data logger to periodically check and measure the voltage. You need to store a minimum daily battery voltage to maintain the battery health and make it last as long as possible. You can even purchase a programmable data logger and program it so that it records whenever the voltage drops below a certain amount.


If your battery needs water, you need to check them regularly. Water levels in the battery should be checked on a consistent basis to ensure that the battery doesn’t start drying up. If you have just installed a new system, it’s recommended that you check the battery levels at least once a week. Also, when pouring water into your battery, make sure that you only use distilled water. Normal tap water is not suitable because it contains various minerals that will ultimately end up reducing battery life. If you have a home battery in Sydney, you should call a professional to check it for you. The electrolyte levels must not fall below a certain level, such as when the lead plates are exposed. This could cause the battery to die very quickly. Also, make sure that you do not overfill your batteries.

Fully Charge the Batteries

To prolong the life of the batteries, you need to make sure that they return to a full charge from time to time. At least once a week, you should charge them all the way to full. This helps in maintaining a healthy cycle of the battery and reduces the damage that’s usually caused when the battery discharges too fast. These are just a few things that you should know about proper battery maintenance.
