The Dyness BF100 141kWh is the higher-capacity variant of the BF100 outdoor DC battery cabinet. It stores 141 kWh in the same rugged IP55+C3 air-cooled enclosure rated for outdoor and rooftop installation. Like the 100 kWh model, it connects on the DC side of existing on-grid inverters, requiring no modification to the rest of the PV system — making it straightforward to retrofit battery storage into commercial sites. Multi-layer BMS and fire detection protection. LFP chemistry for long lifespan beyond 8,000 cycles.
