Collection: Floor-Mounted LiFePO4 Batteries

Floor-mounted lithium batteries suit sites that need standalone energy storage without wall-load concerns. The range covers 24 models across the SunWell floor family, spanning roughly 5.12 kWh to 16.1 kWh at 51.2 V, all built around LiFePO4 cells. Start by calculating your daily evening or backup load in kWh and add a 20 % depth-of-discharge margin. For small residential backup, 5–10 kWh is usually enough; for off-grid workshops or small commercial sites, look at 15 kWh and above. Check the footprint and weight before you commit floor space: larger units can exceed 200 kg and 760 mm deep, while the portable M-series products weigh about 55–68 kg and include wheels for temporary sites. Cycle life across the range is rated at 6,000 to 8,000 cycles at 70 % SOH, so match the cycle rating to how often you plan to discharge each day. Communication is generally CAN/RS485/RS232, and many models add Bluetooth or WLAN as an option, which matters if you want remote monitoring. Finally, confirm the case type matches your environment: floor-standing/wall-mounted dual-use units are flexible, but pure mobile units trade rack-ability for portability.

Installation planning should also include service access and thermal management. Leave at least 150 mm of clearance on all sides so the BMS and any active cooling can work efficiently. Floor-mounted units work well in garages, utility rooms, telecom shelters, and small commercial storerooms where wall loads are uncertain. If the site is prone to dust or high humidity, choose a metal-cased cabinet and keep the unit off the floor on a pallet or stand. For mobile units used at events or construction sites, secure the wheels and route cables away from traffic. Always fuse the DC side close to the battery terminals and follow the supplier’s torque specifications for the power lugs.
