What is the difference between a solar battery and a normal inverter battery?

By Matt •  Updated: 05/03/21 •  6 min read

Solar batteries are used for multiple recharges. The solar battery receives power from the solar panel connected to it. In contrast, the normal inverter battery runs on the chemical reaction between the fluid and the metal plate. It can last for 5 to 15 years, depending on the maintenance.

What makes solar batteries more efficient compared to the normal inverter battery?

Solar batteries are inverter batteries designed to serve a different purpose. The solar battery gets the energy from the connected solar panel. The standard inverter battery is charged using the chemicals and metal installed in the battery. The chemical reacts to the metal and generates electricity to power the equipment.

Once the battery is installed, it can last about 10 to 15 years in the proper maintenance. Comparatively, the solar panel batteries require regular charging.

Charge the solar batteries (how about using electricity) during the day when the sun is shining above and use the stored energy at night. 

Another difference between solar batteries and inverter batteries is the discharge rate. The majority of the inverter batteries come with the C20 discharge rating. The rating indicates the battery will last for 20 hours when fully charge. 

On the other hand, solar batteries generally come in C10 ratings. The battery may discharge within 10 hours of full charging. After the battery is fully depleted, you have to charge the battery again.

Household inverter batteries are used once in a while when there is a power cut. Therefore, the battery may last for longer.

Inverter batteries are known for the higher capacity of storage. When the battery is fully charged, it can produce a sufficient amount of energy to power electronics. 

The energy output is depending on the type of battery you are using it. There is a wide range of options available for inverter batteries. Also, different ratings are given to choose the battery according to your need. 

What is the difference between a solar battery and a car battery?

The primary objectives of these two batteries are to store the energy and facilitate the user when needed. In many cases, the two batteries are similar. These batteries are designed for a special purpose in mind. 

Car batteries are mainly used to start the car and power the lights. On the other hand, solar power batteries are designed to store the energy generated from the solar panel. 

Solar batteries cannot be used in the car as they cannot generate sufficient energy to start the engine.

The car needs a burst of energy for a short period to power the engine. Solar batteries cannot produce high watts. 

Solar batteries are deep cycle batteries. The batteries will discharge over time and can sustain for a long period. Once the fully charged, the stored energy is used to power the connected electronics and equipment. 

The slow depletion rate makes the battery usage for the long hour use. It will keep powering the device until nothing is left to give.

Once the solar battery is fully drained, it requires recharge again. There are two types of batteries available in the market, and one is lithium-ion and lead-acid batteries.

What are the characteristics of Lithium-ion and Lead-acid batteries?

Lithium-ion batteries are favorable when it comes to storing solar energy. They are highly efficient and safe for home use. The deep discharge rate of the battery gives you a long hour of use once the battery is fully charged. 

Comparative the lighter weight of the battery enables the user to move the battery quickly in the home.

Therefore, most of the traveler prefers to use the Lithium-ion batteries to power their equipment. The build quality and improved energy-storing technology make the Lithium-ion battery last longer.

The major component of the Lithium-ion battery is the lithium that is used as the electrolyte. It produces electricity using a chemical reaction. 

It is a lightweight metal that reacts to the chemical and frees up the electronics, which are then transformed from the positive to the negative side of the battery that produces the flow of electricity.

The easy-to-use functionality makes the Lithium-ion batteries an ideal option for home use.

Comparatively, the Lead Acid batteries are designed for the long hour serving. It can store solar power efficient way and offer power over long periods. 

The only problem with Lead-acid batteries is when the battery goes through a charge and discharge cycle, a small portion of the battery performance is lost in the process. 

Over time the gap between the performances would be widened, and the battery will no longer generate a sufficient amount of energy. It also affects the lifespan of lead-acid batteries. 

 Are solar batteries the same as regular batteries?

Solar batteries and regular batteries are two different types in terms of build quality and performance. A significant difference is seen in the discharge rate of these two batteries. 

The solar batteries come with the deep cycle recharge, which allows the battery to store the energy for long hours. Whereas regular batteries can deplete the power quickly when used. 

Solar power batteries are rechargeable batteries that accumulate energy from the solar panel. It stores the energy during the day using the photovoltaic current to use the energy at night. 

Solar batteries are power by the sun, and regular batteries get the power from the local power grid. In most batteries, lead-acid batteries are used, which is maintenance-free. 

Also, they are less harmful. These batteries do not produce harmful gases during the charging process. 

Solar batteries are used in outdoor lighting and solar street lights systems due to their high efficiency. 

Also, once the solar panels are installed, they keep producing electricity which is free of cost. However, regular maintenance is required to keep the battery performance intact. 


The solar battery and standard inverter batteries are great for storing energy using different sources. If you plan to move to renewable energy, then solar batteries are a great choice.

Install the solar panel system to your rooftop or in the backyard and enjoy the free energy throughout the year. 

The regular inverter batteries are generally used as backup energy when there is a power cut.

Also, they are helpful during travel. It can power your essential equipment during travel and keep you connected to the world. Both are useful in different situations of life.
