LiFePO4, the Best Batteries for Solar Systems

Solar power is on trend as a free and sustainable energy source. You may have already installed a solar system on your roof and are benefiting from it. But merely a solar system isn’t a sure card. What if there’s a long power outage occurring just on rainy days? 

Invest in a battery, all is settled.

Why You Need a Battery for Your Solar System

Without an efficient battery, excess solar power is wasted. And you don’t have enough power when the sun isn’t shining.

Storing extra solar energy in batteries, however, allows you to use it later at any time, reducing your dependence on the grid and saving on utility bills. Some batteries support grid connection and allow you to sell the excess energy back to the grid, so you can even earn money from your solar system.

Common Types of Batteries for Solar Systems

Lead-Acid Batteries

Lead-acid batteries have been in use for a long time and are relatively affordable. They offer high surge currents and have a relatively high energy density. Yet, they have a shorter lifespan and require regular maintenance.

Nickel-Cadmium Batteries

Nickel-cadmium batteries are known for their durability and ability to withstand extreme temperatures. They have a long lifespan and high efficiency of charge/discharge. However, they are expensive and contain toxic materials.

Lithium-Ion Batteries

Lithium-ion batteries are lightweight, require minimal maintenance, and offer high energy density. Two main lithium-ion types, the NMC and the LFP, are most popular for solar energy storage.

The NMC batteries are relatively lighter and have a higher energy density. The LFP batteries deliver nearly five times as many charge cycles as NMC batteries and are less prone to catch fire.

Why Choose a LiFePO4 Battery?

LiFePO4 batteries stand out as a favorable option for solar system owners with added safety, stability, and a long life span of up to 3,500 cycles.

Some of the Top LiFePO4 Battery Solutions

There are many batteries on the market and BLUETTI emerges as a leading provider of portable, home and commercial battery solutions. In addition to the inherent benefits of LiFePO4 batteries, BLUETTI battery systems offer some outstanding features.

Self-Heating Function 

Certain BLUETTI products, such as the B300S additional battery for the AC500, are equipped with temperature sensors that enable self-heating in extremely cold weather. This function ensures the entire system operates smoothly, even in harsh winter conditions with temperatures as low as -20° C (-4° F).

Integrated Power System

BLUETTI battery solutions can be complete power systems that integrate MPPT controllers, efficient inverters, multiple outlets, and more. Coupled with many other useful features, such as the UPS function, peak load shifting, off/on grid connection, BLUETTI battery systems can provide uninterrupted power for all needs.

Wide Compatibility

BLUETTI battery systems are widely compatible with existing or new solar systems. They vary in size, capacity, power and solar charging capability, offering different options.

How to Choose the Right Battery System?

For Residential Solar Systems

Large solar systems on rooftops of homes or farms typically generate more power for large energy consumption and require more capacity for storage.  In such cases, BLUETTI recommends its AC500 battery system. Featuring a high power output of up to 5,000W (10,000W surge), it can power any home appliance from refrigerators to dryers. Its modular design allows you to customize your own battery system by adding batteries as needed. The AC500 works with 1 to 6 B300S batteries for a flexible capacity ranging from 3,072Wh to 18,432Wh. This is enough to power a home with an average daily energy use of 3,000Wh for almost a week. Its maximum 3,000W solar input capability enables you to maximize solar power for energy savings. Compared to those wall-mounted battery systems, the AC500 is more movable and easier to set up.

For Balcony/RV Solar Systems

Balcony and RV solar systems typically have smaller solar arrays for partial utility independence. BLUETTI’s all-in-one AC200P or modular AC300 battery systems are designed for these setups. These batteries are compact, moveable, and provide 3,000W or 2,000W power to various devices via their multiple outlets.

In conclusion, selecting the right battery for your solar system is crucial for optimal performance and efficiency. LiFePO4 batteries, such as those offered by BLUETTI, provide outstanding safety, stability, and long-term cost performance. Whether you have a household, or small-scale solar system, BLUETTI offers top-notch battery solutions tailored to your needs.
