48v 300ah Liion High Quality Energy Storage Battery for Solar System

Lifepo4 48v 300ah lithium ion solar battery


When we talk about solar energy battery storage, green energy, comprehensive use cost, and safety are our primary considerations. Safety is particularly important. Usually, the environmental temperature of solar energy storage is relatively high. The excellent safety of lithium iron phosphate battery (LFP) in a high-temperature environment is that it stands out in solar energy storage.

Polinovel solar battery company has been engaged in solar power system energy storage for many years and has rich experience in design and production. Our li-ion solar batteries are widely used in a home house, communication base, vehicle and boat energy storage, and many other fields. Due to our scientific internal safety structure design, combined with our high-quality lithium iron cells, and modern production technology, we can ensure that every battery pack we produce can safely and reliably meet the energy storage needs of our customers.
