Product Introduction
The FLH48100UG2 is equipped with a lithium iron phosphate battery designed for residential use. Developed based on customer needs and market demands, this advanced energy storage system provides high-quality, reliable electricity for various devices. The product offers long service life, excellent performance in high temperature environments and a compact design that requires minimal installation space.
The FLH48100UG2 incorporates a battery management system (BMS) independently developed by our team. When connected to the grid or a photovoltaic system as a power source, the product can store energy by charging the battery. In the event of a power outage from the grid or the photovoltaic system, the system autonomously supplies electricity to household loads. In addition, multiple units can be connected in parallel to form a large-capacity modular system, meeting long-term storage requirements.
