The Dyness BF100 is a 100 kWh outdoor DC battery cabinet designed specifically for commercial solar sites that want to add battery storage to an existing on-grid PV system without a full redesign. It connects on the DC side of existing inverters, so no changes to the AC side of the installation are required. The air-cooled enclosure is rated IP55+C3, suitable for rooftop and outdoor yard installations in industrial environments. Multi-layer safety systems including cell-level BMS protection and fire detection ensure safe long-term operation. LFP chemistry provides an ultra-long service life beyond 8,000 cycles. Available in 100 kWh and 141 kWh configurations.
