Are Lithium Solar Batteries Really the Best Choice for Solar Panels?

Lithium solar batteries are currently the most common battery of option for solar systems. The expensive costs of these batteries are frequently disregarded by solar fans, but are they really worth it? Are these batteries the ideal option for solar panels, or what? Let’s dive in and find out!


What exactly is a lithium-solar battery?

In solar power systems, lithium batteries are simply known as lithium batteries. More specifically, deep-cycle lithium iron phosphate (LiFePO4) batteries make up the majority of lithium ion solar batteries.Lithium salts are used to create exceptionally effective, long-lasting LiFePO4 batteries. Deep cycle batteries like this are ideal for solar applications because they have unexpected charging and discharging cycles.

Why should you fully charge your LiFePO4 battery before using it

Before assembling into a pack and before use, the LiFePO4 cells and batteries MUST be charged to full voltage level for activating. 

Before the battery pack is used for the first time, the cells will be fully charged and balanced in this manner.

Making the initial charging is crucial, even in straightforward installations. In addition to the initial installation, we advise periodically inspecting the battery pack’s cells and performing individual charging to fully balance each cell.

Are Lithium Solar Batteries Really the Best Choice for Solar Panels?

When it comes to storing energy for solar systems, lithium solar batteries perform better than its rivals. They last longer, are more effective, charge more quickly, and need no maintenance.

Extremely low internal resistance, which enables the battery to be charged with fewest losses, contributes to efficiency. Additionally, because they may be discharged with few losses, the energy input and output are equivalent. Any solar energy that is wasted while charging a battery with a lower efficiency is gone forever.

Despite their high initial cost, lithium solar cells are ultimately more cost-effective than other battery types when these advantages are taken into account.

Why is the solar system's battery pack the most crucial component?

Contrary to popular belief, solar panels are not the most important component of a solar system. Actually, the battery pack is to blame. Many people got their start in the solar industry by investing in a few sun panels to power their typical lead-acid batteries. But getting your battery pack first can yield better outcomes.

Solar panels power the battery pack using solar energy. Your system won’t produce electricity when it’s cloudy or the sun sets. Your battery pack is thus your only source of limited power. You have access to more power the bigger the battery pack is. You can charge your battery pack more quickly without using up more battery capacity if you have a sizable solar array.

Lithium solar battery advantages

You’ll immediately see that lithium ion solar batteries are one of the more expensive solutions when you compare them to other battery kinds. The benefits of lithium batteries, however, make up for their high initial costs.

Excellent for irregular solar charging cycles

Depending on the climate, the location, and the season, solar charging conditions can change. Charging can vary greatly from one second to the next, and a cloudy day might practically make a solar array useless. Lead acid batteries can be harmed by inconsistent charging; however lithium batteries are not affected by this.

Because lithium batteries can accept larger charging currents, charging periods are shortened. Lithium batteries are also more understanding of irregular charging cycles. When using lead-acid batteries, the battery must be fully charged after any discharge since doing so will reduce the battery’s lifespan. Lithium battery performance and life are not significantly impacted by partial charge cycles. They are therefore better suited to sunny conditions.

Perfect for irregular discharge cycles

You may use different amounts of electricity from the battery pack on different days. Uneven discharge cycles are easily handled by lithium batteries. Your lithium battery pack can withstand irregularities in discharge without causing the battery any harm, whether it serves as a backup or primary power source. High-quality lithium batteries are generally not significantly impacted by deep discharges, which can harm lead-acid batteries.

Duration of over 5,000 cycles

When people see the expense of lithium batteries, they frequently turn away. But the duration of them is one of the most important considerations. A normal lead-acid battery can hold a charge for 200 to 900 times. Daily solar charging can take up to many years under perfect circumstances and with adequate maintenance.

Lithium batteries, on the other hand, have a known lifespan of more than 5,000 charge cycles, or more than 10 years of operation.

Although initially more expensive, lithium batteries have a longer lifespan. One of the most economical options for creating a battery pack is choosing lithium batteries because they frequently don’t need to be replaced.

Independent of battery power is available power

The voltage of a lead acid battery keeps decreasing as it is being discharged. Typically, you can only utilize about half of a lead-acid battery’s capacity before the voltage is too low to power the electronics. Lead-acid batteries can also be damaged and lose life if they are charged less than 50% of their capacity.

On the other hand, lithium batteries deliver constant power and voltage throughout the discharge process until the battery is totally exhausted. This implies that there won’t be any apparent voltage drop while using the battery to its maximum capacity. Additionally, unlike lead acid batteries, fully depleted lithium batteries won’t harm them.

No battery maintenance vs. lead acid

Given the sheer number of objects that require routine maintenance, it is clear why lithium batteries are a maintenance-free solution. Once you have inserted lithium cells in your battery pack, you can essentially forget about them.

On the other hand, lead-acid batteries require a lot of regular maintenance. Sulfuric acid and water are used as an electrolyte in lead-acid batteries to aid in energy storage. Lead-acid batteries must be recharged frequently because the repeated charging and discharging might cause water to evaporate. Lead-acid batteries should be inspected and refilled regularly to avoid irreparable damage, decreased performance, and shortened battery life.

Even maintenance-free lead-acid batteries require periodic “equalized” charging to stay in good condition. Lithium batteries are the best substitute if you don’t want to increase the number of maintenance tasks on your to-do list.

What Should we Concern When Purchasing Lithium Solar Batteries?

There are numerous varieties of lithium batteries. Before making a purchase of lithium solar cells, there are a few things to think about.

Watt-Hours Rated

You can roughly determine how many amps the battery can deliver for one hour by looking at the amp hour rating (Ah). A 100 Ah battery, for instance, has an hourly capacity of 100 amps, a two-hour capacity of 50 amps, and so on.

The battery has a greater capacity to deliver electricity if the number is higher. The amp hours and useable capacity of a battery pack are increased by connecting numerous cells in parallel.

You must conduct an energy evaluation to determine your battery pack needs before you buy a battery. If your battery pack does not have enough amp hours, you risk running out of power when you need it. Please get in touch with the professionals at Maxword Power Batteries if you have any concerns or need assistance figuring out how much battery capacity you require.

Release threshold

A lead-acid battery’s performance might be negatively impacted and permanently damaged if it is discharged below 50% of its capacity. The battery was made to completely discharge with no damage.

Because the discharge cycle is controlled by our internal battery management system (BMS), the battery is rated for what you actually get. Other lithium solar cells, however, often have a maximum discharge threshold of 80% before the battery starts to suffer damage.

System for managing batteries

Lithium solar cells have an inbuilt battery management system (BMS) that aids in ensuring their safe functioning and long life. The BMS monitors the temperature and condition of the batteries while balancing the charge between them. The battery is turned off by the BMS if it notices a hazardous state in order to avoid harm. A BMS must be present inside the lithium battery you select.


Professional service

In order to correctly calibrate and maximize functionality, solar systems can be highly complex and require substantial understanding. It might be frustrating and regrettable to turn off a system setting. However, not all manufacturers of lithium solar cells have a stellar reputation for their customer support.

Choose a company that has a proven track record of providing excellent customer service. There are many companies ready to accept your money, but you need to make sure they will continue to support you after the sale. If you want to get the most out of your lithium batteries, you need knowledgeable customer service.

Lifetime and Warranty of Lithium Solar Batteries

One of the most recent batteries on the market is lithium solar batteries. As industrial research and technology develop, so do the lifespan and warranties that are offered. Before making a purchase, confirm the warranty’s terms and any prerequisites to prevent the warranty from being voided. In order to make an informed choice, its better for you to confirm what is covered and the replacement procedure too.
