Solar energy is a free and sustainable source of energy that is on the rise. You may have already installed a solar system on your roof and are taking full advantage of it. But the solar system alone is no guarantee of security. What happens if a long power outage occurs on a rainy day?
Invest in a battery and it’s all set!
Why do you need a battery for your solar system?
Without an efficient battery, excess solar energy is then wasted. And you don’t have enough energy in storage when the sun isn’t shining.
Storing extra solar power in batteries allows you to use it later, anytime, reducing your reliance on the grid and saving you money on your electricity bills. Some batteries also connect to the grid and allow you to resell excess energy, so you can even earn money from your solar system.
Common types of batteries for solar systems
Let’s take a look at some of the main battery types and their characteristics:
Lead-acid batteries
Lead-acid batteries have been used for a long time and are relatively affordable. They provide high current peaks and a relatively high energy density. However, they have a shorter lifespan and require regular maintenance.
Batteries au nickel-cadmium
Nickel-cadmium batteries are known for their durability and ability to withstand extreme temperatures. They have a long service life and high charge/discharge efficiency. However, they are expensive and contain toxic materials.
Batteries au lithium-ion
Lithium-ion batteries are widely used in rechargeable electronics technology and electric vehicles. They are lightweight, low maintenance and offer high energy density. The two main types of lithium-ion batteries, nickel manganese cobalt oxide (NMC) and lithium iron phosphate (LFP), which are the most popular for solar energy storage.
NMC batteries are relatively lighter and have a higher energy density. LFP batteries allow nearly five times more charge cycles than NMC batteries and are less likely to ignite in the event of extreme overheating.
Why choose a LiFePO4 battery?
Indeed, LiFePO4 batteries are the best option for solar systems. They are safer, more stable and have an impressive lifespan of up to 3,500 cycles, making them a long-term investment for solar system owners.
Some of the best LiFePO4 battery solutions
There are many batteries on the market and BLUETS has established itself as a leading provider of portable, home and commercial battery solutions. In addition to the inherent advantages of LiFePO4 batteries, BLUETTI battery systems offer exceptional characteristics.
Self-heating function
Some BLUETTI products, such as the B300S Supplemental Battery for the AC500, are equipped with temperature sensors that allow self-heating in extremely cold weather. This feature ensures that the entire system operates smoothly, even in extreme winter conditions, with temperatures ranging as low as -20°C (-4°F).
Integrated power system
BLUETTI battery solutions can become complete power systems that integrate MPPT controllers, high-performance inverters, numerous outlets and ports and much more. Combined with many other useful functions, such as UPS function, load peak shifting, grid connection “off/on”, BLUETTI battery systems can provide uninterrupted power for all needs.
Wide compatibility
BLUETTI battery systems are widely compatible with both existing and new solar systems. They vary in size, capacity, power and solar charging capability, providing an answer to all types of needs.
How to choose the right battery system?
For residential solar systems
Large solar systems, installed on the roofs of houses or farms, generally generate more energy for a large energy consumption and require greater storage capacity. In this case, BLUETTI recommends its EP600 and AC500 battery systems. These batteries offer high power output, up to 9000W and 5000W respectively. Both batteries are modular in design, and you can customize your own battery system by adding additional batteries as needed.
The EP600 runs on 2-4 B500 batteries for a flexible capacity ranging from 9,920 Wh to 39,680 Wh, which can power a home with an average daily power consumption of 3,000 Wh for almost a week. Its grid connection capability also allows you to resell the extra solar power to earn money. Backed by a 10-year worry-free warranty, this battery will benefit both you and the environment.
The AC500 stores a maximum energy of 18,432 Wh when paired with the B300S. Compared with EP600, it is more portable and easier to install. It requires no electrical expertise, just plug it in and use it.
For balcony or motorhome solar systems
Solar systems for balconies and RVs are very popular today. They are usually equipped with smaller solar panels for partial independence from power companies. The BLUETTI AC200P or AC300 battery systems are designed for these types of installations. These batteries are compact, mobile and provide enough power for various occasions.
The AC300 modular battery has a maximum storage capacity of 12288Wh when connected with the B300 battery and provides 3000W of power. The AC200P can draw 2000W from its built-in 2000Wh battery. What they have in common is a wide choice of output options that allow everything to be plugged in and charged.
In short, choosing the right battery for your solar system is crucial for optimal performance and efficiency. LiFePO4 batteries, such as those offered by BLUETTI, offer exceptional long-term safety, stability and cost-effectiveness. Whether you have a home or small-scale solar system, BLUETTI offers best-in-class battery solutions to suit your needs.
