Productinformation in detail
Compact Energy for Home
The B4850 battery module from Dyness offers a flexible and reliable energy storage solution, specifically designed for residential applications. Thanks to the lithium iron phosphate technology (LiFePO4), this module ensures maximum safety and a long lifespan. The modular design allows for easy expansion and customization to meet individual needs by connecting multiple modules in parallel. With a capacity of 2.4 kWh per module, the B4850 provides effective storage of excess energy from photovoltaic systems.
Robust and Versatile
The B4850 battery is characterized by its resilience, as it is designed for extreme temperature ranges from -20°C to +55°C. The modular design allows for use in various environments, both for off-grid and hybrid systems. Additionally, installation is particularly straightforward, as the battery is stackable and can be mounted with flexible brackets. The system also supports leading inverter brands and offers comprehensive compatibility with devices like SMA, Victron, and Goodwe.
Intelligent Technology and Durability
Equipped with a battery management system (BMS), the B4850 module monitors the condition of individual cells and ensures safe operation by providing protection against overcharging, overheating, and short circuits. With a lifespan of over 6000 charge cycles and a depth of discharge (DOD) of 90%, this battery is optimized for long-term operation. Through modern communication via CAN and RS485, it is also easily integrated into existing energy systems and ensures efficient energy flow.
