How to choose lithium batteries for energy storage?
In the solar energy storage system, the role of lithium battery is to store electric energy. Due to the limited capacity of a single battery, the system usually combines multiple lithium batteries in parallel to meet the designed voltage level and capacity requirements, so it is also called lithium battery pack. In the photovoltaic energy storage system, the initial cost of the lithium battery pack and the photovoltaic module is equivalent. The technical parameters of lithium batteries are very important to the system design. During the selection design, pay attention to the key parameters of lithium batteries, such as battery capacity, rated voltage, charge and discharge current, discharge depth, cycle number, etc.
48V Energy Storage Lithium Battery
The 48V low-voltage energy storage lithium battery product independently developed has a complete set of property rights for R&D, design, and production, and has the following main advantages:
1. Long life and safety
The safe new lithium iron phosphate battery and reasonable and rigorous product design and manufacture make the battery life more than 6000 times (DOD 80%, 0.5C, 25℃).
2. Intelligent
Each battery has an independent and efficient BMS system, which can intelligently and effectively manage power output and comprehensively protect battery safety.
3. Modularization
Each battery can support a maximum of 16 in parallel, and end customers can choose according to their household power consumption.
4. Easy to install and use
Just plug and play to minimize the installation time and cost. The compact and fashionable design fits in your sweet home environment.
5. Compatibility
With RS485, CANBUS, RS232, and other communication protocols, it can be perfectly compatible with all off-grid or hybrid inverter brands.
