This case presents a practical mid-to-large scale residential energy storage solution using two LFP.1433.F LiFePO4 batteries, paired with a DEYE hybrid inverter. With a total energy capacity of 28.66kWh and usable capacity of 27.22kWh, this system is designed to meet the daily consumption needs of homes with higher energy demands, as well as provide backup power for critical loads.
Each LFP.1433.F unit delivers 14.33kWh of energy (13.61kWh usable), operates at a nominal voltage of 51.2V, and supports a wide operating voltage range (44.8V–57.6V). With a continuous charge and discharge current of up to 140A, the system is capable of running power-intensive appliances such as air conditioning, water heaters, and EV chargers without significant performance degradation.
Built with cobalt-free Lithium Iron Phosphate (LiFePO4) cells, the battery ensures high safety, thermal stability, and long service life—rated for over 6000 cycles at 0.5C and 25°C. The compact design (900×400×260mm) and modularity allow for flexible installation and future expandability, with support for up to 16 units in parallel, reaching a maximum capacity of 229.28kWh.
The system integrates smoothly with the DEYE inverter and is also compatible with most major inverter brands, making it ideal for both new installations and system upgrades. Weighing 115kg per unit, it is suitable for floor-mounted indoor setups.
For installers and distributors looking to offer dependable and scalable battery storage solutions for residential or light commercial clients, this field-tested configuration offers a strong balance of safety, capacity, and long-term reliability.
