“LVYUAN” Why is 51.2V the best? Advantages of using high voltage batteries in solar power generation systems
From September 2023, LVYUAN will begin selling 5.12kWh and 10.24kWh LiFePO4 batteries (51.2V).
Solar energy systems are shaping the future of sustainable energy supply, but at their core they require efficient energy storage. When choosing a battery for this purpose, we focus on 51.2V high voltage batteries.
At our company ““, we are working hard to introduce independent solar power storage systems to all our members. The power generation systems installed for home use range from 3,000W to 11,000W, and are provided to members in various sets. “For hybrid power generation systems, we divide them into 24V systems and 48V systems based on the battery. There is only one 24V system, and the rest are all 48V systems (44V to 54V range). In this report, Learn why 51.2V batteries are the ideal choice for solar power generation systems.

1, high energy transmission efficiency
One of the most notable features of the 51.2V battery is its high energy transfer efficiency. This high voltage significantly reduces energy losses in cables and connections. This is a key factor in increasing overall system efficiency and reducing long-term operating costs.
2, Battery Management System (BMS)
LVYUAN’s 51.2V battery consists of 16 3.2V cells connected in series. This design is highly compatible with battery management systems (BMS) that easily monitor and adjust the status of each cell. This optimizes battery performance and extends its lifespan.

LVYUAN’s 51.2V battery can store a large amount of energy in a relatively small size. Such characteristics are extremely valuable, especially in homes and small-to-medium commercial establishments, where space is at a premium.
4. Consideration for the environment
Additionally, LVYUAN’s 51.2V battery is made of environmentally friendly materials such as lithium iron phosphate. These batteries have high thermal stability and are highly resistant to overcharging and overdischarging.

compatibility, space efficiency, versatility, and environmental friendliness. These properties make them extremely valuable in achieving a sustainable energy future. Therefore, 51.2V batteries are an ideal choice when designing and implementing solar power systems. Second, why it is not recommended to build a 12V battery into a 48V system For 12V batteries, a maximum of 4 in 4 parallel (4S4P) connection method is generally recommended, but this method has some drawbacks. 1. Energy loss and efficiency issues
First, connecting a large number of batteries in parallel or series tends to cause energy loss. In particular, it increases resistance in cables and connections, which can reduce energy efficiency.
2. Complexity of battery management
Additionally, the 4×4 connection scheme makes it difficult for the battery management system (BMS) to accurately monitor and adjust the status of each battery. This increases the risk of some batteries becoming overcharged or overdischarged, which can impact overall system reliability and lifespan.

The 4-skewer system requires a large number of batteries and connecting cables, which results in more space and more complicated installation. This type of design can be particularly disadvantageous for homes and small-to-medium-sized commercial facilities, where efficient use of limited space is required.
[Image 5:×1000.jpg] For the above reasons, the 12V battery 4-in-4 connection method may not always be the best choice in terms of energy loss, battery management complexity, and space efficiency.
