Types of Batteries Used with Inverter, Life & Warranty

Solar energy systems generally consist of solar batteries as well as panels, mounting instruments, and a quality surveillance system. The sun’s energy is captured by solar panels, which then convert it into energy that can be used in your household, office, or industrial area. 

Since most homes are connected to the grid, these structures are more commonly used as a backup by homeowners. Yet many people are on the lookout for a new source of energy. People switch to solar for a variety of reasons, including the desire to avoid high energy costs.

Numerous solar batteries are being used as a backup plan for serious loads in instances of grid collapse. You can choose from a variety of solar batteries to power your system, whether you need an immediate backup like such a UPS or a high-powered option. As a result of their design, the solar batteries charged by these panels are designed to be used as a backup power source.

Types of Batteries Used with Inverter

The energy produced by solar panels is stored in solar batteries. Incorporated energy conversion and efficiency monitor might indeed come with their inverter.

A solar battery’s storage capacity is related to its type. As opposed to re-feeding solar power directly into the grid, the solar battery stores it for later consumption. It will send energy to the grid once your batteries are fully charged. As soon as the battery is being used up and its charge is drained, the battery will start charging again and draw power from the panels once again.

Residential solar energy systems are generally used to power batteries, but batteries can be used without solar panels. In the scenario of small thermal energy storage, electricity from the grid could also be used to charge batteries. The solar battery is indeed the energy storage component of your solar panel system. These batteries can be used when the solar panel isn’t producing any electricity.

Depending on how well the batteries are charged mostly by solar cells, these batteries could provide 100 per cent of such self-sufficiency needed by house owners who live entirely off-grid.

Power failures in businesses or homes can be disastrous, but a solar battery bank can provide a solution. When it comes to adverse weather conditions, you’ll need a backup generator more than ever. 

Solar battery banks are becoming increasingly popular as a means of supplying power during occasions when utility prices are at their highest. In order to achieve your goals, you can use this emerging technology in your homes and businesses.

Do You Charge Lithium Batteries?

Yes. The charge response of lithium batteries, among many other factors, can cause them to be compromised by regular charging. Bulk, acknowledgement, and float are the three stages of charging for most types of solar batteries. For their part, lithium batteries require two stages of charging.

Initial charging takes place at a constant voltage when it’s almost full. During the second and final phase of being able to charge, the charging amperage will be allowed to drain. It is also possible to damage lithium batteries when charging them in a store, as this can result in an increase in withdrawal and shorten the battery life.

Different Types:

  • Lead Acid – 

In off-grid regions, lead-acid batteries are being used for several years as a sustainable source of energy. They are usually low-cost and have a long life cycle. They are known for their high power and discharge current, but they have a limited amount of stored energy. They take a long time to fully charge – up to fourteen hours.

Owing to their highly toxic nature, these batteries must always be discarded properly or they could indeed pose a risk to the environment’s health. Floating and valve-regulated lead-acid (VRLA) battery packs are the most prevalent forms of lead-acid batteries used during solar panels.

Leaded batteries that have been filled with water and vented properly are a reliable option. 2 categories of VRLA, gel and absorbed glass mat, are available with valves for off-gassing regulation (AGM). In both cases, they can be used in cold and warm temperatures. If you’re considering a permanent alternative to your grid power supply and are considering VRLA batteries, you should be aware of their sensitivity to temperature.

  • Lithium-Ion – 

Globally, solar systems are increasingly relying on lithium-ion batteries. Because of its implementation in the electric car industry, the development and introduction of batteries are critical. When used in solar systems, its prismatic shape facilitates ventilation.

When it comes to voltage scale and trying to charge response, lithium-ion batteries are unmatched (two stages as opposed to the conventional three). Using a voltage regulator charge controller, they can be recharged. Long-term charging is not beneficial to lithium-ion batteries, regardless of their actual self-discharge.

Generally speaking, this type of solar battery is low maintenance, seems to have high specific energy, and has a long lifetime. Most lithium batteries cost more than lead-acid ones. Additional circuitry for current and voltage regulation may be required.

It’s generally accepted that lithium-ion batteries offer more cycles per charge than lead-acid batteries, which makes them ideal for providing grid ancillaries. A lithium-ion battery’s high charge and discharge efficiency are indeed one of the energy-saving features, making it a good choice for a solar system. Additionally, these batteries have a lower capacity loss when unused, which is advantageous in solar installations within which energy can only be used on a limited basis.

Life & Warranty:

A solar battery’s life is the best indicator of how well it will perform in your system. It’s the process of charging a battery after it has been discharged, and it’s the main way to determine how long the battery will last. How many cycles your solar battery will go through is also determined by how much you use it. 

Even the same application of solar battery will have different characteristics, and the battery’s depth of discharge will have an impact on this attribute. When it comes to brands and products in general, warranties indicate dependability, and solar batteries are no exception. 


The frequency of power outages on your grid availability must be taken into consideration when choosing a battery solely for backup purposes. If it won’t be used more than a few times, a minimal maintenance battery like the sealed lead-acid solar battery will be more beneficial. When it comes to industrial sites, lithium-ion batteries are the best choice.
