- Larger Solar Energy Storage: In homes with larger solar energy systems, medium-capacity LiFePO4 batteries are used to store energy for later use, ensuring that homeowners can rely on stored power during the night or periods of low sunlight.
This range strikes a balance between size, weight, and energy storage, making it ideal for applications that demand moderate amounts of energy while still requiring portability and efficiency.
High-Capacity 36V LiFePO4 Batteries (300Ah – 400Ah)
At the higher end of the spectrum, 36V 300Ah to 400Ah batteries provide substantial energy storage and are typically used in more demanding commercial or industrial applications:
- Commercial Renewable Energy Systems: 300Ah and 400Ah LiFePO4 batteries are widely used in commercial-scale solar or wind energy systems. These batteries store large amounts of renewable energy, ensuring continuous power supply even when generation is low.
- Electric Vehicles and Industrial Equipment: High-capacity 36V LiFePO4 batteries are also found in electric vehicles (EVs) and heavy-duty industrial equipment. Their ability to provide extended operational hours without frequent recharging makes them ideal for electric forklifts, commercial EVs, and other machinery requiring significant power output.
- Backup Power Systems: For mission-critical applications, such as telecommunications and data centers, these high-capacity batteries are used in backup power systems to provide uninterrupted power in the event of a grid failure.
High-capacity LiFePO4 batteries deliver large amounts of energy while maintaining the safety and durability that these batteries are known for. They are ideal for long-term, high-demand applications where reliability is paramount.
