Deye BOS-B Pro-A3 257.23kWh LiFePO4 Battery System, 819.2V 314Ah High Voltage
This is the size you use to store energy for a factory, not a house: sixteen 16.08kWh modules in series inside a single rack, 257.23kWh nominal and 231.51kWh you can actually use at 90% depth of discharge. System voltage reaches 819.2V, which keeps current low for the same power and stops the cabling from becoming the bottleneck of the installation.
The system is designed to pair with a 100 or 125kW PCS and to be replicated: putting several racks in parallel takes you up to 2.5MW without changing the architecture. The modules are LiFePO4, maximum charge and discharge current is 180A, and a rack can hold anywhere from five to sixteen modules — so you can start smaller today and add modules later without throwing anything away.
Size and weight need planning before you order: 2150 × 1305 × 800 mm for about 2,240 kg as a complete system. You need a floor that can take the load, decent access and pallet transport with a specialised carrier, which we quote on the delivery address. CE, IEC 62619, IEC 62040 and UN 38.3 certified; 10-year warranty.
