Dyness DL5.0C Pro 5.12kWh LFP Battery Storage Module
The Dyness DL5.0C Pro (part number DY-DL5.0C-PRO) is a 5.12 kWh lithium iron phosphate (LiFePO₄) battery module designed for residential and small commercial energy storage. With a 95% depth of discharge, 1C maximum discharge rate, and cycle life of 6,000 cycles or more, the DL5.0C Pro supports both off-grid and hybrid system configurations. Up to 50 units can be connected in parallel for a maximum system capacity of 256 kWh. The battery features built-in WiFi with APP OTA functionality, CAN/RS485 communication, and an automatic self-heating function for operation in ambient temperatures as low as -20°C. Available from DECO Group, a UK-based solar wholesaler supplying trade installers and electrical contractors.
