The Dyness BF200-DC is a 215 kWh outdoor DC battery cabinet from the BF Series, designed for large commercial and industrial facilities looking to optimise their energy costs. Smart tariff scheduling allows the system to automatically charge during low-cost periods (solar peak or off-peak grid) and discharge during high-tariff hours, reducing electricity bills significantly. The IP55+C3 enclosure handles outdoor installation without any weather protection structure. Like other BF series cabinets, it connects on the DC bus of existing PV systems with no modification to the AC side. Air-cooling keeps internal temperatures in check. LFP cells with long cycle life and multi-layer safety protection.
