The efficiency and reliability of your solar panel system ultimately depend on the batteries you use to store energy. Although lead-acid batteries are cheaper, they may not be the best for the job in the long run due to their short lifespan and the need for regular upkeep. That could make them more costly down the line. Consider investing in a lithium battery for solar storage to avoid the hassle. Here are reasons why lithium batteries are better than tubular lead-acid batteries.
Efficient
A lithium battery is more efficient than lead-acid. That means you can store and use more solar power. Tubular batteries are only around 80 to 85 percent efficient. So, if they’re receiving 1,000 watts of solar power, they can only provide 800 to 850 watts after charging and discharging. Lithium batteries are at least 95 percent efficient and can offer more than 950 watts of power based on the previous example.
High efficiency also means the battery can charge faster. Lithium batteries may even reduce the need to buy more panels and a big generator.
More depth of discharge (DoD)
Lead-acid batteries must run only to 50 percent DoD, or their lifespan will suffer. A lithium battery for solar storage can accommodate deeper discharges of at least 80 percent, meaning more usable capacity.
Better charge rate
Lithium batteries are more efficient, which means a faster rate of charge and the ability to handle more amperage from a charger. That means they can recharge faster. There’s a limit to how much charge current lead-acid tubular batteries can manage. This is because they tend to overheat when recharged rapidly. Charge rates also slow down toward full capacity.
Energy density
Lithium batteries have more energy density, allowing them to accommodate more solar energy despite their reduced size. That can be beneficial when you need to mount a battery bank in a tighter space or a suspended enclosure.
What lithium battery should I use?
Now that you know why you should use a lithium battery for solar storage, you’ll want to identify the best type of lithium technology. Lithium-iron phosphate (LiFePO4) is the lithium battery technology for that purpose. It’s proven to last longer and can endure deeper cycles without requiring venting or maintenance.
